After upgrade to proxmox Backup Server 3.3 I've got some fail jobs with status: TASK ERROR: Aborting GC for safety reasons: nested datastores not allowed: 'BACKUP350' already in "/mnt/datastore/BACKUP350".

I know that I have some tenants as a new one datastores inside this but how to resolve it.
 
Forum members would need this info in order to assist.
Some problems are thorny to solve. This is probably not one of those.
I expect you'll get an explicit answer here. Just ... help us help you.

zpool status

zfs list

df -h

cat /etc/proxmox-backup/datastore.cfg


BTW ... do get this fixed. If GC isn't running, your datastore may fill up.

you have nested datastores, which is not supported. PBS recently got upgraded to detect and warn this.

datastore: BACKUP350

move that datastore to another location if it is used, or remove it if it isn't..

Let me try rephrasing that.


This bit encapsulates all the following bits.

datastore: BACKUP350
path /mnt/datastore/BACKUP350


See? The next one is inside it.

datastore: u352717488
gc-schedule 14:00
path /mnt/datastore/BACKUP350/u352717488


So your problem is that first one.
If you don't have to mount that, then remove it.
If you do need to backup stuff to that root directory ... well, like fabian said, you need to move it.
