Restore Failed

[Petr Konderla]

Hello, trying to restore(3times) backup and it has failed randomly around 18 - 50 % with timeout.
The versions are Proxmox 6.2-12, PBS 0.9-1.

Both are running HP Server (HW Raid) with EXT4 Backend, Gigabit connectivity (on the same switch).
Backups check are fine.

It's testing version, so it's not end of the world.

Cheers

could you include both pveversion -v output on the PVE side, as well as proxmox-backup-server version on the PBS side? also, the task log on the PBS side would be interesting.

since you can reproduce it, can you try running the qmrestore command with RUST_BACKTRACE=1 qmrestore ?

Here are the versions, qmrestore is just running...

Hi, seem to be fine now, I've used this command.
qmrestore pbs.pickering.cz:backup/vm/1000/2020-10-19T09:26:36Z 1000 --force

It's that different from pbs-restore (which has been used by proxmox gui)

btw: incremental backup is great, what about incremental restore .

qmrestore calls the same API code that the GUI uses, which then (for a PBS backup) calls the pbs-restore binary to do the heavy lifting.

I assume you mean something like take existing data and backup and just overwrite those parts that don't match? in most cases that won't be more efficient than just doing a full restore, which is also much simpler. if you find yourself wishing for such a feature often, you might want to look into setting up storage snapshots in addition to backups, then you can cheaply rollback to previous snapshotted states.
