Is PBS "compatible" with docker?

Hello!

I'm trying PBS for the first time, and I'm facing some trouble with the backup of just one of my containers.

This problematic container is running docker (Portainer, Traefik and a bunch of others).

There are 3 volumes attached:

1) root disk: 6GB (backup=yes)
2) /opt: 8GB (backup=yes)
3) /var/lib/docker: 8GB (backup=NO)

So, even excluding the disk 3) (that uses that "fuse-overlay2"), the backup of this container never ends...

I tried a few times (more than 5, I guess) and now the current backup is running for more than 4 hours:

Code:
(...)
INFO: including mount point mp11 ('/opt') in backup
INFO: excluding volume mount point mp12 ('/var/lib/docker') from backup (disabled)
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: suspend vm to make snapshot
INFO: create storage snapshot 'vzdump'

which I think is a little bit longer for this container size.

So, is there anything regarding dockers and/or overlay that prevents the backup to PBS?

I don't know if my case is related to this one.

I'm running PVE 7.2-7 and PBS 2.2-5

Thank you!
