    Do any of you use the Backup over WiFi option? I turned that off on mine although I never leave the app running I thought it would just complicate things and I still prefer to use a cable for reliable syncing.

    I think I used it once, then turned it off. Didn't have any issues with it, just didn't want to clutter the WiFi network with that much data. Maybe later backups don't use as much, if they use the TM approach of incremental backups, but I have cables handy, so...

    I use it all the time and it works just as well as using the lightning cable and attaching the devices to my iMac. I do the same with iTunes and that works okay as well.

    Within the limitations of practical space we just can't have too many backups.

    I leave mine enabled too. I also leave it enabled across all three user accounts (I leave them logged in as well) and they back up at different times.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    Hmm, okay, maybe I will give it a try but Bob are you using a desktop to do that? I’m just on a MBP.

    Yes, I'm using my Mac Mini. But it still should work the same way on any Mac model.

    Hey everyone! iMazing team member here. Will do my best to help you understand how iMazing uses disk space and answer other questions which were raised in this discussion.

    Any additional questions and comments are more than welcome!

    iMazing backup folder structure

    By default, iMazing will back up to 'C: \Users\*user name*\AppData\Roaming\iMazing\Backups' on Windows and to '~/Library/Application Support/iMazing/Backups' on Mac. Here you will see two types of folders:
    - Folders with 40 random chars in name (device UDID, unique for each device).
    - iMazing.Versions folder.

    Folder with 40 random chars in name is the last full backup of your device. There will be one separate folder for each device you back up with iMazing.

    iMazing.Versions folder contains incremental versions of previous backups in iMazing.Versions > Versions folder. Backup versions themselves are saved in folders named by device UDID, so they won't mix up.

    Checking space for iMazing folder itself will also count cache and .ipa files saved in 'Library' folder.


    Backup size, space used report and backup archiving

    iMazing backups are similar to Time Machine and are incremental (basially shallow copies), and will include only changed data where possible. So, for example, Photos db is not fully copied each time you make a backup after taking a new photo, just changed files.

    Also, as backups don't include iOS, apps .ipa files, and media, they will be actually smaller than space used on the device.

    Regarding space used by incremental backups, Finder and File Explorer don't count incremental backups correctly and include additional full backup in report. For example, if you have a 100 GB main backup and total incremental backups size for this device in iMazing.Versions is 120GB, actual space used for incremental backups is 20 GB. Terminal should give the correct report.

    iMazing will also keep an eye on how much space is taken by incremental backups, and will delete older backups in case they start taking more than 50% of your full backup size. Check this guide for more info.


    'iMazing/Library' folder can use a lot of space

    'Library' folder is where iMazing stores .ipa files that you download with Manage Apps feature, so better to keep an eye on it. Especially if you save version history of some apps.

    It's a good idea to set it to an external drive (if possible) with Preferences > Apps tab.


    Cache taking a lot of space

    iMazing generates cache to speed up performance. If it takes too much space, you can always clean it manually: quit iMazing and iMazing Mini (to make sure no cache files are in use) > relaunch iMazing, but don't open any dataset > Preferences > General and click 'Clear iMazing cache'.


    Changing backup location and backing up to external drives

    iMazing can use external drives and NAS as backup locations. When changing backup location, iMazing will start a fresh backup set and old backups won't be moved automatically. As the first backup is full, it's better to connect device via USB. If you use NAS as your backup location, connect it to your computer via Ethernet cable (if possible) for the first backup to speed up the process. Second and further backups will be incremental, so you can use Wi-Fi.

    Note: Moving iMazing.Versions folder manually with Finder or File Explorer will break incremental backups system. We are currently working on the way to move full backup set with iMazing, but not sure when it will be implemented, unfortunately. If you have some important backup that you want to save for extra security, you can export it using this guide and mount it in iMazing later.


    Deleting iMazing backups

    As iMazing backups are incremental and connected with each other, deleting them manually may lead to backup set corruption and data loss. You need to delete backups only with iMazing.

    If there are any issues with deleting backups, first restart your computer and, if they won't go away, please let us know through support form or just send a message with Help > 'Send feedback or bug report' inside the app!

    Note: Incremental backups can be really small, so deleting one or two may not free up any noticeable ammount of disk space.

    'Endless backup' issue

    I've seen a case with backup starting over on 20% in one of the first comments, so I'll cover it as well. When backup takes too much time, some apps can refresh in background. This will lead to changed files on the device, and iMazing will need to start the backup all over again.

    It's usually fixed by simply restarting both device and computer, putting device in Airplane mode and starting the backup.

    What can affect backup speed:
    - Backup location. Fastest backups are with local driver, slightly slower with external drive and can be very slow on NAS (depends on WLAN and lots of other factors).
    - Free space on the device. During backup, Apple's backup agent will generate temp files so it needs some free space. We recommend having around 5-6% of free space from device's total disk space.
    - Connection type. Wi-Fi backups are always slower than wired backups.


    Hope this helps!

    Welcome to the forum, iMazingTeam! You said:
    iMazing can use external drives and NAS as backup locations. When changing backup location, iMazing will start a fresh backup set and old backups won't be moved automatically.
    This statement is key. In my case, and I don't think I am that unique, I had two devices that had been backed up using iMazing, so the first full backups were about 150GB total. Then because the incremental backups later fit into the same folder but with a new date attached, TM saw the file as changed, so it took a snapshot, using another 150GB of space. I changed the location of the backup to an external, but as the statement said, the original was not moved and not deleted, so the 300GB was tied up. I ended up deleting iMazing altogether, then used Finder to wipe out all of the backups on the internal drive, reinstalling iMazing and immediately configuring it to point to the external drive and started over. I ended up recovering over 300GB on the internal drive. Some of that was the original backups (about 150GB), some were the snapshot and the rest was cache that got reset and deleted with the uninstall process.

    The only reason I started this thread in the first place is so that other users would look to see if they also have similar space being consumed by the iMazing backups. The product is good, and I'm still using it. iMazing tech support was supportive through the process. I have no beef with them, or with the product, but the fact is that if you let it back up to the internal drive, it could end up costing you a lot of space, maybe more than you know and can afford. I avoided having to buy a new 2T SSD to replace my 1T drive by freeing up 300GB. My SSD got down to less than 150GB remaining on a 1TB drive, but now has 460GB free.
