all previous snapshots will not be list with "btrbk list" after linux recovery

[XueqiangDong]

Has linux on /mnt/linuxes/opensuse Has snapshots on /mnt/snapshots/opensuse/20220815T0000, 20220816T0000, 20220817T0000, 20220818T0000, 20220818T0100... Suppose met some problem of the current os and want to recovery to 20220817T0000:

Recovery form the backup snapshot sudo mv /mnt/linuxes/opensuse /mnt/linuxes/opensuse.bak sudo btrfs sub snapshot /mnt/snapshots/opensuse/20220817T0000 /mnt/linuxes/opensuse

And after reboot, after the cron job run of btrbk All the snapshots (/mnt/snapshots/opensuse/20220815T0000, 20220816T0000, 20220817T0000, 20220818T0000) will be deleted and btrbk will create the snapshot from the start of it's first run after recovery Fortunately the backup snapshots are still there and didn't be deleted

It's not "deleted", it's just that "btrbk list" command don't list the previous snapshots. If I use manual "ls /path/to/snapshots" canmand I can still find the snapshots. So I changed the title

"btrbk list" shows you how the subvolumes according to the config. Still, if nothing changed in the config, i.e. no diff in /mnt/linuxes/opensuse /mnt/linuxes/opensuse{,.bak}/etc/btrbk/btrbk.conf btrbk should actually list the ones from /mnt/snapshots.

If you want to list your btrfs subvolumes, try "lsbtr -l" (as of btrbk-0.30.0 I think, I always recommend using latest version). gives useful listing especially for disaster-recovery ;-)

not sure what "lsbtr -l" is and in my opensuse it says command not found. But it's fine this strange not listing issuse happens only on openSUSE, and not found in other distros (Debian, Arch, Fedaro). I can still list the btrbk backup snapshots with "sudo btrfs sub list /xxxx" and just not list by "btrbk -c /xxx.conf list" command for openSUSE. Nothing serious there.
