PBS Client "Partial" access denied but still success?

[USER372214]

Running into an issue running the proxmox-backup-client backup command on a debian 12 bookworm client. The initial backup succeeds, but on subsequent backups the client is showing repetitive failed to open file: "partial": access denied errors, even though the backup still appears to succeed.

Here is a snapshot of the output:

Permissions wise, the User has admin permissions for the datastore, and the token has Datastore.PowerUser for the namespace.

Any Ideas on what "partial" is? Or methodology to discover more information? Looking at the PBS syslog Server side, I see no errors with the backup, and it states that the backup finished successfully.

Hi,

Running into an issue running the proxmox-backup-client backup command on a debian 12 bookworm client. The initial backup succeeds, but on subsequent backups the client is showing repetitive failed to open file: "partial": access denied errors, even though the backup still appears to succeed.

these are warnings, showing you do not have access to read some file along the filesystem tree of the directory you are trying to backu up. These will be ignored and not included into the backup snapshot, but are not considered a hard error.

Any Ideas on what "partial" is? Or methodology to discover more information?

I would guess this is a file/directory your local user called user (which runs the backup job), does not have the permissions to access. You can try to run find /home/user -name partial -exec stat {} \; to find out more about these files.

Looking at the PBS syslog Server side, I see no errors with the backup, and it states that the backup finished successfully.

That is expected, as there is no error, the files you do not have access to by the user executing the backup client are skipped as mentioned above.

Hey Chris, thank you for your response - You were spot on. The "partial" permission denied error was an old set of containerization files I had messed with, buried deep down in the home directory.

This is pretty awesome, and Thank you and your team for all your hard work. Looking forward for the backup client to support more hosts.

Have a great day and Happy holidays!
