PVE-zsync && QEMU agent

[dea]

I use PX 4.3 and qemu agent works great on backups.
If I use a different method to clone a running VM (for example pve-zync) qemu agent call vss function in the (Windows) VM or works only during the backup ?

Thanks

Hi,

pve-zsync does not use qemu-guest-agent.

OK, is possible to call manually enable /disable VSS (through qemu-agent) before/after run pve-zsync ?
The MS$ SQL don't like the VSS lack ....

Very thanks

Luca

Not directly but you can make your own script.
We provide no hocks in the pve-zsync.

Perfect with a script.
I can call qemu-agent before, run pve-zsync and recall qemu-agent after.

How can I call qemu agent from bash command line to enable/disable ?
qm parameter ?

OK, open a new thread to works on qemu-agent on command line.

Thanks

Good to know. I also thought about the integration of qemu-agent and snapshots:
Does the same apply to "create snapshot" on ZFS? If not, is this a good feature request?

The qemu-agent uses has sense only in snapshots without ram copy.
I need to clone the vm storage and the VSS uses (throught qemu-agent) is desirable specially for MsSQL and Exchange VM.

Of course, yes. I regularly snapshot my ZFS pools, so it's basically the same as pve-zsync would do.
