How to prepare your Mac for a backup

Hard drives have finite space and that space can run out quickly if you’re continually backing up items that you don’t need.

To ensure that your hard drive has enough room for all of the important stuff, you should use CleanMyMac X routinely to detect and instantly remove system files and folders hogging up space.

CleanMyMac X’s Smart Scan feature scans everything on your Mac, including Mac System, Large & Old Files, Photos and iPhoto Libraries, Mail Application, iTunes Library, and Trash Bins to find the things that are safe to get rid off. And using it couldn’t be easier.

1. Download CleanMyMac X (for free).
2. Launch the app and select Smart Cleanup.
3. Hit Scan and wait while CleanMyMac readies items for cleaning.
4. Hit Clean and watch in awe as your hard drive suddenly gains free space that you never thought was possible.

How to back up your Mac locally

A local backup is the fastest way to backup your data. It involves moving your files over to an external hard drive. HDDs and SSDs have dropped greatly in price in recent years so you should be able to pick one up relatively cheaply with a decent capacity. Local backup is a safe and reliable way to safeguard all of your important files and it’s really easy to do.

How to back up your Mac computer to an external hard drive

Most external hard drives don’t come pre-formatted for Mac, so this is a job you’ll need to do before transferring your files. If you’re using an older hard drive that already has data stored on it, formatting will erase it, so you might want to transfer any files over to a different device before hooking the hard drive up to your Mac.

You can format a hard drive using Mac’s Disk Utility feature.

1. Connect the hard drive to your Mac.

2. Go to Applications > Utilities and launch Disk Utility.

3. Select the hard drive that you want to reformat from the Disk Utility.

4. Click Erase and confirm.

5. Rename the hard drive (e.g. “Mac backup”).

6. Choose a new volume format from the following options:

  • macOS Extended (Journaled)
  • macOS Extended (Journaled, Encrypted)
  • macOS Extended (Case-sensitive, Journaled)
  • macOS Extended (Case-sensitive, Journaled, Encrypted)
  • MS-DOS (FAT): For Windows volumes that are 32 GB or less
  • ExFAT: For Windows volumes that are over 32 GB

If you’re unsure of which option to choose, go for Extended (Case-sensitive, Journaled, Encrypted). This keeps your data organized and encrypted, and differentiates folders with upper and lower case letters.

7. Go to Security Options and check that the drive is set to overwrite past data at least three times.

8. Click Erase and confirm.

How to back up your Mac using the Time Machine

Mac’s built-in Time Machine feature is the easiest way to perform local backups. If you’re using an iMac, you can keep your hard drive connected to your computer and set Time Machine to perform scheduled automated backups. Of course, this isn’t always practical for MacBook users who often work on the go.

  1. Go to System Preferences > Time Machine and make sure it’s turned on.
  2. Under Select Backup Disk choose your hard drive.
  3. Click on Options to check that the settings are configured to backup everything you want to save.

Time Machine will begin performing automatic backups, allowing you to retrieve any data from the moment the process started.

How to back up your Mac files manually

If you only want to backup certain files, you can do this manually using drag-and-drop.

  1. Open the Finder and select your hard drive.
  2. Open the window that includes the folders that you want to move.
  3. Drag-and-drop the folders into the hard drive window.

Cloning your Mac backup hard drive

Cloning lets you create a bootable copy of your hard drive for an extra layer of protection that you can fall back on if ever your Mac is out of action.

With the tool like Get Backup Pro, you can clone your hard drive and be sure you’ll be able to boot the backup anytime — be it APFS or HFS+.

How to back up your Mac with iCloud

Local backups are quick and easy but, like your Mac, physical hard drives are susceptible to failure and catastrophes like flood, fire, or burglary. Storing data in the cloud removes these risks and it too is very straightforward, particularly in the case of iCloud.

Once iCloud is up and running you no longer have to worry about losing any of your photos, music, mail, contacts, calendars, reminders, notes, or Safari data. iCloud gives you 5GB of free storage to get you started, with options to upgrade to as much as 2TB of storage space.

Before setting up iCloud to automatically backup your data, make sure you’re running the latest version of Mac. You can find this out by choosing Software Update from the Apple menu and checking if an update is available.

  1. Go to System Preferences and click iCloud.
  2. Enter your Apple ID and select the service you’d like to store in the cloud.
  3. Click on the Option button next to Photos and select the iCloud Photo Library, My Photo Stream, and iCloud Photo Sharing.
  4. Open iTunes and select Preferences. Choose Downloads and select Music, TV Programmes, Films, and Apps.

Save Mac data with live cloud backups

Daily backups are great, but what happens if you’re in the middle of an important assignment and your Mac suddenly crashes? You lose everything you’ve been working on for the past hour.

To prevent this, it’s worth knowing how to backup your MacBook Pro or iMac using live backups. Live backups save everything you’re working on as you go in the same way that iCloud instantly saves your photos to the cloud.


There are dozens of tools out there to help you backup and sync data in real-time, but the big players are the best: Dropbox, Microsoft OneDrive, Google Drive, and Amazon AWS. For encryption and expanded storage space, use CloudMounter to connect your cloud storage accounts to Mac’s Finder.

Don’t risk losing your important files

Backup your Mac now! Don’t put it off. System failure can happen at any time and for any number of reasons. We really don’t want it to happen to you. Use a combination of local and cloud backups so that you’re protected against every eventuality, and make the most of a tool like CleanMyMac X to ensure your hard drives never run out of space.

CleanMyMac X is the easiest way to rid your Mac of system junk, ensuring your hard drives always have space for the things that are important. Download it for free today.

Fortunately, Mac Leopard users have a program called Time Machine that makes things a lot easier. But is Time Machine the perfect backup solution? I don’t think so. There are a couple of things that make Time Machine very unsuitable for me:

  • You need to get a seperate external hard drive that can only be used for Time Machine (and has to be formatted first)
  • That drive has to be formatted in HFS+, hence, without any (commercial) third-party plugins it’s not readable on Windows or Linux systems
  • You have to leave your drive on all the time to make sure Time Machine makes backups
  • You can’t make a list of things you want to have backed up, you can only exclude folders from your complete hard disk
  • Time Machine makes an exact copy of your hard drive

How To Backup Macbook Pro

Especially that last ‘feature’ is very irritating to me. I have an external drive with about 300G of files, including lots of music and video files. My MacBook drive is only 80GB big, so i can never have the complete contents of my external drive on my MacBook. Let’s say i have 10GB of MP3 files, which i backup with Time Machine, then i remove about 5GB of files from my MacBook to free some space. What happens when the next backup round is happening? Exactly, the 5GB of files get deleted from the external disk as well. When i want to play a certain MP3 file from my external drive i now have to ‘restore’ and ‘look back in history’ to find it. Not very user-friendly.

Luckily, there is a very good (free) alternative to Time Machine that does exactly what i want with backups: it lets you specify which folders you want to backup, it doesn’t delete things on the backup drive when you delete files from your original drive, and it’s compatible with any external drive and can even backup files over a network. This piece of software is called rsync. Here’s how to use it.

rsync is a command-line utility shipped with every copy of Mac OS X. It originated from the UNIX/Linux world, where it has been part of most Linux distributions for many years. rsync is reliable, fast, and easily configurable. Try running it by opening up the (located in your Applications/Utilities folder) and running the command:


You’ll get an overview of all possible options. In essence the syntax is very simple:


What you’ll probably want is a one-way transfer of all files in SOURCE to DESTINATION, where only files are copied that are not available on the DESTINATION disk or different. Aside from that you’ll want to include all subdirectories, links, permissions, date/time, groups, owner and devices. To do that simply use this easy-to-remember option list:


rsync -rlptgoD

Ha, just kidding! Fortunately there is another switch that does all of that with one switch, namely the archive switch:

rsync -a

So, let’s say you want to backup the files in your Documents directory to your external harddrive, which you appropriately named ‘backup’, then this would be the command:

rsync -a ~/Documents/ /Volumes/backup/Documents

For those of you who don’t use the Terminal very often: the tilde (~) is a shortcut for your home directory. If, for example, your name would be ‘Alice’ your home directory would probably be


Online backup for mac

In essence you could write the statement above also as

rsync -a /Users/alice/Documents/ /Volumes/backup/Documents

The /Volumes/ path always leads to your drives under Mac OS X. This is also true for DMG files and CDs and DVDs you load.

An important thing to remember is that you should always include a trailing slash (/) after the SOURCE directory and no slash after the DESTINATION. If you wouldn’t do that, and you forgot the slash after ~/Documents rsync would create a directory named ‘Documents’ in the /Volumes/backup/Documents directory, so your files would eventually be backed up under


If you want to get a little more feedback on what rsync is actually doing you can add a few more options to let it output a little more to the screen:

rsync -a --progress ~/Documents/ /Volumes/backup/Documents

You might also want to exclude a few sub-directories or files with the backup. A good example of this is the virtual machine files Parallels makes in the /Documents/ directory and which can be quite large and will be backed up every time. If you have a large virtual machine, this could easily take 15 minutes.

rsync -a --exclude Parallels/ ~/Documents/ /Volumes/backup/Documents

Another option that you might need is when you use a FAT-32 formatted drive. FAT-32 is currently the only filesystem that is supported by all major operating systems, until Apple finally adds write support for NTFS under Mac OS X (There is a very good free / open source alternative called NTFS-3G that works beautiful, but isn’t supported officially by Apple yet). FAT-32 has a shortcoming that it can’t handle files over 4GB, which is pretty irritating if you have large DV video files or DVD backups. Another shortcoming is that it doesn’t properly set file update times, so it will copy all files, modified or not, every time you run your backup. Fortunately, there is a switch to fix this:

rsync -a --modify-window=1 ~/Documents/ /Volumes/backup/Documents

So, we have all the ingredients to make a proper backup script with only the directories you want. What i did to make my own backup script is simply copying the rsync command many times with alternate source / destination paths. A Linux guru could probably come up with a better solution, but this solution works fine for me. For some inspiration for your own backup script, here’s a portion of my script:

rsync -a --progress --exclude Parallels/ ~/Documents/ /Volumes/backup/Documents
rsync -a --progress ~/Music/MP3/ /Volumes/backup/Media
rsync -a --progress ~/Pictures/ /Volumes/backup/Media/Pictures
rsync -a --progress ~/Backup/ /Volumes/backup/Data
rsync -a --progress ~/Movies/ /Volumes/backup/Media/Video

Note the first line of the script (‘#!/bin/bash’). This line says that it is a script executed by the shell. To make this script runnable you need to set some permissions. If you named your script ‘backup’ this would be the command

chmod u+x backup

Now simply run the backup script at any time you like and be very happy knowing that your data is safe on your external hard drive!

Just one last word of advice: rsync isn’t as fool-proof as Time Machine. If you would, let’s say, per accident swap the SOURCE and DESTINATION values you would lose data. Be very careful before running your backup script with any valuable data.

So, hopefully this article has given you some advice on how to use rsync to back up your Mac. Feel free to drop any comments in the comment field below.

    “You need to get a seperate external hard drive that can only be used for Time Machine (and has to be formatted first)”


    The hard drive can be used for other things as well. It doesn’t have to be external either. It doesn’t even have be separate, but you’d be stupid to think that backing up your only hard drive to your hard is any kind of protection.

    Still, it doesn’t seem time machine is a good match for you since you don’t want the kind of backup solution it offers (complete and mindless backups).

  • Tim

    This was just what I was looking for. I have an old HHD from old PC. And just want to backup the Documents folder on my new iMac. And do it whenever I what, whithout having the HDD on all the time. Much, much easier than figuring out how TimeMachine works/doesn’t work. thanks!

  • Grover

    Thanks for the very straightforward overview of using Rsync. It was exactly what I needed to solve a problem I was having.

    Is Time Machine your girlfriend or something? Why are you taking it personally that Mr. Kranen wants to use something else?

  • Xl Organism

    This was exactly what I was looking for. Thanks for posting this. Ciao!

  • Kranki

    1) TimeMachine does not do a complete backup of your harddrive. Do a full restore and you will find (for instance) that you are missed the “/User/Shared/SC Info” directory which is your iTunes authorization data. Apache will be missing a directory.
    2) I have yet to do a full TimeMachine backup and have it be 100% of what I used to have. For instance, recently my harddrive failed and I did have to do a full restore. Well, things like Terminal started having lines through it that just did not exist prior to the backup.
    3) If it were implemented as a full backup such as what you can do with asr or hdiutil, but with history. Then I would be more positive on it. But for now it is back to rsync, hdiutil and asr.

  • Anonymous

    What would be your strategy for creating multiple backups…as in how Time Machine keeps archives of backups along the lines of daily/weekly for up to one month? I like Time Machine, but I don’t like that it requires my network drive to be on all the time. I’d rather make one backup per day (not hourly like Time Machine wants), but also be able to keep archives as far back as one month, like this:

    1. Daily backups for one week (last 7 days worth)
    2. Weekly backups for one month (4 backups)

    Hopefully I’m explaining this clearly. Thanks.

  • Hay

    @09: you could write a cron job that makes a backup every day and another one that archives them weekly. Note that this means that you end up with many duplicates of the same files, that might fill up your backup disk pretty quickly. The beauty of Time Machine is that it takes up less space because it uses symbolic links.

  • dantux

    If anyone is interested, I posted some time ago, my rsync backup script. It does just that: saves hourly, daily, weekly, monthly, yearly backups using the same concept as Time machine does (hard linking). This does not hard link directories, but does for existing files, which saves a lot of space.
    Check it out:

  • Drew Stephens

    Time Machine actually uses hard links, not symbolic links, allowing the oldest backups to be removed when space runs out on the backup drive.

    FAT32 can handle drive up to 16 TB, the 4GB limit is imposed in Microsofts Format command which artificially limits the ability to create large volumes.

    This seems originally to be a move to force people to upgrade from Win98 to win2000 and NTFS if they want large disk support. Most external hardrives are formatted as FAT32 using the manufacturers own version of a formatting tool with no 4GB limits at all

    There are utilities that will format a FAT32 volume in excess of 4GB that can be found with a simple web search

    As a new Apple user – this is another example of an OS not allowing it’s users any flexibility.

    Backup via Time Machine could be useful if it was written in such a way as to allow the user to choose what is backed up and schedule it accordingly.

    I know, Apple people will bleat loudly, but the OS has some significant drawbacks for users that know what the are doing and, don’t want be nannied.

    You need to get a seperate external hard drive that can only be used for Time Machine
    -> Wrong! You can backup to a partition on your internal harddisk if you want. (Would be stupid, but it IS possible) Also, the same goes for EVERY other backup program. Also, the disk is NOT exclusive for Time Machine. It’s just a drive with files and you can add/edit/delete files all you want.

    (and has to be formatted first)
    -> Depends; I ALWAYS buy Western Digital drives in the Studio range; preformatted for mac. My choice. If you choose another; formatting takes about 3 minutes.

    That drive has to be formatted in HFS+, hence, without any (commercial) third-party plugins it’s not readable on Windows or Linux systems
    -> We’re backing up a Mac, what’s wrong with using a Mac file system? Second; the better linux distros can read HFS+ without any trouble. It’s Windows that sucks big time.

    You have to leave your drive on all the time to make sure Time Machine makes backups
    -> Well, I’d like you to show me ANY ONE backup that can backup to a disk that is not on.

    You can’t make a list of things you want to have backed up, you can only exclude folders from your complete hard disk
    -> Which serves it’s purpose very well; that way you cant forget to include newly created files/folders.

    Time Machine makes an exact copy of your hard drive
    -> As opposed to ….. what, exactly? What is wrong with having a full copy of your drive? I don’t want to spend hours reinstalling my OS, then my Apps and then my files after a crash. I used to have to do that with WIndows and I’m sick and tired of that. With Time Machine, i place a new drive, boot from the OS CD and recover my drive. Easy as that.

    I really like your approach with rSync, but your reasoning is flawed.

    @Anonymous #16; As a new Apple user – this is another example of an OS not allowing it’s users any flexibility.
    -> OSX _IS_ giving it’s users all the flexibility it can give; Use Time Machine for a full backup with revisioning, or use rSync (shipped with it) for the more complex tasks. Compared to windows; no backup software to speak of, no revisioning, no rsync.
    On a Mac, there is NO reason whatsoever to not backing up your harddisk. On Windows there is, well, windows IS the biggest reason but that’s beyond the scope of this topic.

    @Kranki #8
    I do not share your (bad) experience with Time Machine. I’ve restored not many machines but a few and all of them restored without any problem whatsoever (including our mac mini server that lost a drive due to a power outage)

    Why do so many say it’s silly to backup a hard disk to another portion of the same hard disk? For me, one HUGE value of backing up (with whatever method, but preferably with some form of history) is to get an earlier version of a file I messed up. In fact, that’s the only reason I’ve ever actually used a backup in practice (I admit: I’ve been lucky). OK, it WOULD be silly to not ALSO backup to an external drive for protection against the drive crash scenario… It does happen, I know. And I will do that too. Just don’t discount the value of a simple historical copy of the work you do as part of everyday workflow.

    For the curious: I use TM to backup up my SSD drive to the internal HD on my iMac. In addition, I use a sym link from my desktop to a “working” directory on the HD (I don’t want my every day files to start filling up the SSD), and hoped that TM would back up that working directory too. Not surprising, but unfortunate: it faithfully backed up the sym link, but that’s it — meaning that the TM backup process doesn’t FOLLOW the sym link and backup the files & directories it finds there. (Of course, I can’t use a hard link since it’s across file systems.) So an rsync solution such as described here is something I’m considering for that “working” directory.

    Similarly, I’ll probably develop an rsync solution to fully backup the HD to an external device, for that rare day when the HD decides to croak. Yes, I could use TM itself, manually switching it from the SSD to work instead with the HD, then switching back after its done (yuck) — or fool with the TM plist to do the switching. Much to do, much to learn….

    rsync -a is missing -H

    So, if you want to preserve hardlinks then you need to add that option.
    This will increase the amount of time it takes for the overall rsync to perform.

    And, this is not necessary if you are backing up directories that you know do not include hardlinks. However, if you are backing up system directories, you may want to be sure and include that option.

    • It’s safe to partition a hard drive to include the backup. Since it is a sep partition directory failure will not affect the backup files.
    • If a disk is not mounted & misses a scheduled backup, Time Machine immediately initiates a backup when the backup drive returns
    • Time Machine completes an initial full backup with future backups only containing changed or new files, its incremental.
    • Time Machine respects other non-Time Machine files on the backup drive, but the more files on the backup drive the less available space for Time Machine backups
    • Time Machine keeps recent backups, a weekly backup & a monthly backup.

    Hi Hay, Thank you for sharing a great comprehensive article on rsync. I have been trying all possible operators in my rsync command but I have failed to sync my MBA with External Hard Drive exFat. The file Created Date changes to the date I run the script. Weirdly, the files Modified Date and Last Open Date don’t change.

    Script Editor command below:

    tell application “Terminal”
    do script “rsync -a –update -raz –progress /Users/me/Documents/ /Volumes/TT1/documents” in front window
    end tell

    Is this to do with rsync not handling permissions on exfat?
    Thank you in advance.

    Cheers, A.

    Better than time-machine. Lol. Catchy title though. Dude I was searching for an alternative to rsync on windows, too many came up. Tried them, useless they were. My friend told me to use GS Richcopy 360. Man, that one suggestion solved everything. This Richcopy 360 is pretty dope!

  • TimeMachine cool and i tell you why

    What you are comparing here is a filebased backup via rsync with a full system backup with TimeMachine. But that’s a unfair comparison for both programms.

    TimeMachine not only produces a (what you didn’t mention your article) a bootable drive, with a recovery system, but it saves your data incrementally, like rsync does.

    I have a 1TB drive (internal) as a backup drive and a system drive 1TB (500GB used). 10 backups on my backup drive could only mean, that TimeMachine don’t simply makes an 1:1 image of your drive. Thats cool, and theres place for 10 more…

    1.) TimeMachine backups every day, every hour, if i want that, even when i forgot to make a backup, TimeMachine does it. Cool!

    2.) You can restore your complete system with your TimeMachine backup and even can choose, which backup do you want to restore. Cool!

    3.) It backups while you are working with your Mac, transparently and nearly unnoticable. Cool!

    4.) As you see now, you can use a internal drive also, no problem with that, it’s much faster that way. Cool!

    I really don’t understand the arguments, that your are writing in you article. Your way of backup doesn’t produce a bootable, full backup, so it is absolutely not usable, when your hard disk crashes and you want to reproduce the working system again.

    Your arguments, my answers:

    * You need to get a seperate external hard drive that can only be used for Time Machine: Wrong, you can use it like any other drive, i copy my mp3 on my backup drive and TimeMachine does’t have a problem with it

    * That drive has to be formatted in HFS+, hence, without any (commercial) third-party plugins it’s not readable on Windows or Linux systems: Of couse you have to… This is the same under Windows with NTFS. By the way, Linux can read and write HFS+ out of the box

    * You have to leave your drive on all the time to make sure Time Machine makes backups: Of couse… Can you make a rsync backup without a drive? But with TimeMachine you can also just start a backup whenever you want and disconnect your drive after that, and connect it for the next.

    * You can’t make a list of things you want to have backed up, you can only exclude folders from your complete hard disk.Time Machine makes an exact copy of your hard drive: Yes, that’s the reason, why so many of use TimeMachine, to have a working copy of the hole system, that you can restore completely, if your harddisk fails.

    What you suggest here is a simple file backup, not a system backup. And that’s obvisiously not the same.

    rsync is cool, i use it too. But TimeMachine has a clear purpose in Mac OsX, and is cool too. Just use both, for both and different use cases.

    I found your article quite helpful on how to use rsync on OS X. However, I disagree with you about Time Machine. First, when you delete files from the MacBook the files aren’t actually “deleted” on the Time Machine disk, but merely hardcopies of them. And although you can much around in there, that’s not how the way you use time machine.

    You use the “back in time” interface. I know it sucks a bit and it’s slow, but it has improved a little over the years. It’s differently the thing that they need to improve the most on or change it altogether. Although for users like my mom and dad it works wonderfully (?).

    The problem with rsync is that is that it’s really easy to make a mistake. Manage large files you need deleting with. And with no snapshot support you’ll basically have to run rsync yourself. And that violates ones of the rules of backup, you want an automated system that backups on its own, and still have files you deleted X days/weeks ago.

    I use ZFS myself on FreeNAS for all my file needs. Built a cheap little $300 machine that can fit more hard drives and run more plugins than any other $600 NAS units. I run Time Machine on it, as it has space for all machines. So no more external drives. I think I saved money overall. :)
