Snapshot "snap-sync backup in progress" to be deleted after completion?

[Thomas]

Hi,
I have this list of snapshots on my server:

Is my understanding correct that any snapshot with description "snap-sync backup in progress" should be deleted after a successful sent to backup location?

If yes, this code
snapper -c $x delete $(snapper -c $x list | awk '/'$name' backup in progress/ {print $1}')
should not work because snapper delete <number>.
snapper -c $x delete $(snapper -c $x list | awk '/'$name' backup in progress/ {print $3}') should work, though.

The fact that you have these snapshots means that the backup was interrupted. But it looks like you have successfully backed up since then, so they could be removed.
