Hi,
with a Setup like
PBS <--->| GW VM |<--> PVE Host
where the GW VM is running on the PVE Host and connecting the PVE Host with
the PBSever, I seem to run into a race condition when trying to
snapshot-backup the GW VM to the PBS Server.
The snapshot appears to freeze the GW VM just the moment the PVE Host tries
to establish the connection to the PBS:

TASK ERROR: job errors
on a "Fast" Setup meaning fast Hosts and LAN, it works sometimes, sometimes
it fails.
on a "Slow" Setup meaning non powerfull Host Hardware and VPNs via LTE, this
always fails.
This is with PVE 6 and PBS 1.1
Any ideas to work around this? Not sure if I'd consider this a bug.
Regards,
Tom
