Filesystem snapshots

[dignus]

Hi,

I've been a long time happy user of Proxmox, untill we decided to move to ovirt. Now that Proxmox is able to work with LXC, we're considering adding a Proxmox cluster.

One of the questions I have, can't find the answer: if using containers and requesting a backup, will proxmox create a tar of the container (like in the old days) or will it use the snapshot capability of the underlying filesystem (if available)?

I don't want to work with local storage, for failover purposes. What would the recommended storage be? We have a ZFS cluster available, able to export over NFS & iSCSI. Would ZFS on top of an iSCSI be the way to go?

Also - what is the maximum size of a proxmox cluster these days?

Hi,

"tar of the container (like in the old days)"
yes

"the snapshot capability of the underlying filesystem (if available)?"
yes

yes would be a way or ceph server on PVE.

what is the maximum size of a proxmox cluster these days?
we are supporting 32 nodes but do not limit them.
So the max dependent on some factors.
