CA Appdata Backup / Restore (v2)
Due to some fundamental problems with XFS / BTRFS, the original version of Appdata Backup / Restore became unworkable and caused lockups for many users. Development has ceased on the original version, and is now switched over to this replacement.
Fundamentally they are both the same and accomplish the same goals (namely, backing up your Appdata share and USB / libvirt), but this version is significantly faster at the job.
This version uses tar instead of rsync (and offers optional compression of the archive - roughly 50% if not including any downloads in the archive - which you really shouldn't be anyways).
Because of using tar, there is no longer any incremental backups. Rather, every backup goes into its own separate dated subfolder. Old backups can optionally be deleted after a successful backup. Even without incremental backups, the speed increase afforded by tar means that there should be no real difference in the end. (ie: A full backup using my appdata on the old plugin takes ~1.5 hours. This plugin can do the same thing uncompressed in about 10 minutes, and compressed in 20 minutes. The optional verification of the archive takes a similar amount of time. An incremental backup on the old plugin using my appdata averaged around 35 minutes).
The options for separate destination for USB / VM libvirt backups is changed so that if there is no destination set for those backup's then they will not be backed up.
Additionally, unlike the original plugin, no cache drive is necessary, and the appdata source can be stored on any device in your system (ie: unassigned devices). The destination as usual can go to any mount point within your system. Unfortunately because of no more incremental backups, this version may no longer be suitable for ultimately backing up offsite to a cloud service (ie: via rclone)
You can find this within the Apps tab (Search for Appdata Backup).
The original v1 plugin should be uninstalled if migrating to this version.
