Restore to FAT32

[ojaksch]

I regulary backup a bunch of SD cards and other medias, which in this case are having FAT32 partitions, to PBS by mounting the media and doing a simple

proxmox-backup-client backup BACKUPNAME.pxar:MOUNTPATH --backup-id BACKUPNAME

to the appropriate repository. This is working great and blazing fast in contrary to cp or rsync.

But restoring the pxar to a FAT32 mounted media fails and exits right after the 1st file with

Error: error extracting archive - error at entry "FILENAME": failed to set ownership: Operation not permitted (os error 1)

This is comprehensible as FAT lacks of typical permissions, ownerships, xattrs etc.pp. I bypass this circumstance by restoring to a tmpfs and moving the files to the mounted media, but this is contradictory in my eyes. What I'm missing here is a parameter like "ignore special permissions" or "ignore errors and continue".
Or is there another option that I may not be seeing right now?

Asking good questions and helping yourself is a great thing, even after a good breakfast and after a glass of fresh beer this hot sunday noon
Leaving the question above open I've managed to restore things to a FAT mounted device by

proxmox-backup-client restore host/BACKUPNAME BACKUPNAME.pxar - | pxar extract - /mnt/fat32card

This is also working fine and faaaast, despite that it's throwing masses of failed to set ownership: Operation not permitted (os error 1) messages, but it's working. So question itself solved but leaving open a request for a parameter ("ignore errors") to proxmox-backup-client.

Yes? Maybe? Or "Computer says NO"?

yes, i think a 'ignore metadata errors' (chown/xattrs/acls/...) would make sense
would you mind opening an enhancement request: https://bugzilla.proxmox.com
(maybe there is already such a request, can't remember right now)

Just done at the Bugzilla as I've found nothing similar there. Glad you agree with me
