$ cd /Volumes/my_backup/Backups.backupdb/my_mac/Latest Then open Terminal and go to the last Time Machine snapshot: You will need the Universal Unique Identifier value select it with the mouse, copy it, and paste it somewhere for use later. Next, open Disk Utility, select your new partition and press Command-I to display the partition's information. It does seem to work with an image copy, though.Īfter the image is done, remove the old drive/partition, or otherwise disable it, so that you're not confused by its presence - all commands that follow will refer only to the new partition, and a change will be made only to a folder in the Time Machine backup. I have not tested whether a mere file copy of a partition can be re-connected successfully so that only incremental backups are made. The copy will be almost identical to the original - only the drive ID (UUID) will be different, and that is why Time Machine would try to make a complete backup if we didn't do something to prevent it. Progress will then be shown as copying blocks instead of copying files. Don't forget to select Erase Destination, or it will in fact just make a file copy. #OPENZFS CARBON COPY CLONER MAC#In Disk Utility, select the target disk (which must have been partitioned so your Mac can actually boot from it!), click Restore, drag the target partition to the Target field, and the old partition to the Source field. Start from a different disk if you want to copy the system partition (use the System DVD if necessary). I know it works with an image copy of your partition.ĭISCLAIMER: Do this at your own risk! Have a backup of at least your most important files on a separate medium! Do not attempt this if you are uncertain about any of the consequences or circumstances here! There are no guarantees that the following will work for you! In this case, I used this hint to re-connect Time Machine after migrating a partition from one hard disk to another one. #OPENZFS CARBON COPY CLONER SOFTWARE#Then you'll see that the archaic storage-expensive solutions necessary in commercial software consoles simply do not apply in linux.This hint is inspired by and uses tricks introduced by the hint Repair Time Machine after logic board changes, and is used for a similar purpose. Spend a couple of minutes reading up on snapshotting and modern linux filesystems and how everything in linux is a file, and you'll understand how easy it is to backup data in linux systems and to snapshot installs/configs. Snapper with a home profile will just take a snapshot of userspace. It will be incredibly fast and small because it uses the functionality of btrfs and zfs to do so. #OPENZFS CARBON COPY CLONER FULL#Snapper with a standard root profile will take a full system snapshot. The most used snapshot application is snapper. Btrfs and zfs will both offer full data correction (no more data rot, so smaller chance of ever needing a backup), and snapshot capabilities. Btrfs has much lower system overhead than zfs, but can't or shan't be used in complex raid configurations. Two of those are particularly interesting, because they are fully hashing journalling filesystems: btrfs and zfs. Linux has much more advanced file systems than commercial software consoles. As in linux everything is a file, a recover from such a backup will also just work. If you perform that as root or system, a recursive root backup will include the entire system. So full snapshots including all data are a pretty big waste of resources in linux.īut nonetheless, you can cron a backup operation. It's a pretty useless feature in linux to take full disk copies because as everything in linux is a file, a system is entirely interchangeable, meaning you could take your /home folder to another system and it'll just work there just the same, including userspace apps. If there is some linux software that can do this I have no problem paying for it.
