FAILED 04:03:30 error pruning backups - check log

Hello all,

I'm having issues with a backup of a vm on my proxmox server (version 6.4.8). The backup destination is a drobo NAS with a CIFS/Samba share, here's the error:

100: 2021-06-25 08:59:15 INFO: removing backup 'drobo-35:backup/vzdump-qemu-100-2021_06_21-05_00_02.vma.zst'
100: 2021-06-25 09:02:22 ERROR: error when removing backup 'drobo-35:backup/vzdump-qemu-100-2021_06_21-05_00_02.vma.zst' - removing archive /mnt/pve/drobo-35/dump/vzdump-qemu-100-2021_06_21-05_00_02.vma.zst failed: Resource temporarily unavailable
100: 2021-06-25 09:03:32 ERROR: Backup of VM 100 failed - error pruning backups - check log

I have my backup retention to keep at least 4 copies and it is working properly this way. The last 4 backups I have are from 6-22, 6-23, 6-24, and 6-25.

Any ideas what I need to do? It is working, but honestly I'm getting tired of seeing the Failed error message. lol

I have a similar problem with our backup jobs to a synology share. Did you find any solution or did it get fixed after upgrading?
