ZFS Raid1 (2x 'cheapo' SSD) - additional single drive for backups?

[jaceqp]

Hi there.
I'm doing some maintenance on a desktop based 'server' used as SQL database host for ca 5 LAN users.
It was running bios-software RAID1 on 2x Samsung EVO 250GB SATA SSD's. I know that those are NOT server grade but what can you do :/ 3rd drive is a regular 3,5" 1TB SATA for backups etc.

Now, after a clean install Proxmox with ZFS RAID1 on SSD's I'm thinking of using additional hard drive for VM backups. Not sure how though.
I created a new ZFS pool with SATA drive attached, then added ZFS storage but only content I can set is Disk image and/or Container. It seems that I can't use this type 'mounting' and use it for vzdump-type vm backup. Shall I set this disk lets say in EXT4 instead in order to use proxmox based vm backups?

Obviously ZFS has some fancy stuff but I might need to extract VM (or Virtual Disks) backups to lets say samba share or usb drive.

BTW. If having two ZFS pools like above: SSD (RAID1) plus storage_1TB can I somehow perform backups one to another on a ZFS level?

Hi,

if you use the ZFSPool plugin only KVM and LXC are possible.
You have to use dir plugin when you like Backups.
