Proxmox and PBS - "starting first sync" - local vm dump dir

it takes about 1 hour/1.5 hours to backup currently, and the first step is putting the entire image in the Proxmox tmpdir/vzdump dir - this is taking over 45/55 minutes, and then... after the tmpdir/vzdump dir , it should copy/"increment" the backup. However, it doesn't seem much faster than just doing a full backup if it's just making a full copy in the first round, then sending it off to PBS. (I refer to /etc/vzdump.conf)

It doesn't seem much faster to me when the first round of backing up with PBS is making a full copy to my local tmpdir/vzdump dir (which can take a while unless you're on SSD.... and then giving it to PBS...

I am running PBS as an LXC (to test this system) and made directly attached storage available for the backup. Am I missing something? Because if it's doing a full copy and putting it into tmpdir/vzdump dir and then copying it over to PBS, I'm not sure it's very fast.


Any thoughts on this?

Are you sure you are backing up using the proxmox-backup-client and not vzdump?
proxmox-backup-client will most certainly not place a copy of your VM data in a vzdump tmpdir...

Did you set up PBS on the PVE host as pbs storage backend as described here? https://pbs.proxmox.com/docs/pve-integration.html

So, PBS was added under data center -> storage
A backup request was made for an LXC and because of mount points it does suspend mode, I found that all the backups were doing the usual vzdump tmpdir and then sending it to PBS.
I couldn't seem to get any VM's to backup either:

It seems that there is an issue with detecting one of your volumes. Please post the output of pveversion -v and qm config 108

Sorry for the late reply.

This backup issue happens to all VM's. It's only just about working for LXC's - although when suspend is used it's using vzdump tmpdir
