[SOLVED] Force sync of snapshots of snapshots with "failed" verification status

[antipiot]

Hi everybody!

I have a Proxmox backup server that is synced to a remote one.
Lately, some of the verifications job on the remote Proxmox backup server started to report failed verifications on some of the snapshots.

Thoses snapshots appears to be OK on the main proxmox backup server.

I wanted to force sync of thoses snapshots, but even if i delete one, the server does not sync "old" snapshots.
How can i force the sync of missing ones / recover thoses data?

Regards

this is currently not possible (a "re-sync" feature is being worked on though).

as a workaround, the following should work, unless you already have a complicated namespace setup (if you do, please post details!):
- create a new namespace on target datastore
- sync (or pull) using the same parameters as the existing sync job, but with the target namespace pointing to the newly created namespace

since the namespaces share a chunk store, only those chunks which are missing and the metadata of all snapshots should be downloaded. afterwards, you can re-verify the corrupt snapshots in the original namespace to clear the verification error, and then drop the namespace you created since it's no longer needed.

@fabian : Thanks you very much.
Followed your steps and started a new verification, now everything is OK.
