PBS supprot for pve with ISCSI(LVM) storage

[parker0909]

Hello,

May i know it is possible to support the backup for PVE if i using the storage via ISCSI SAN storge with LVM volumn?
it seem snapshot should not support in LVM volumn,so i guess it also not support the pbs snapshot backup. May i know any backup solution to suggest for LVM volumn VM data. Thank you.

For backups: yes, it works! (Though I do not have something like this, so I can not test/verify by myself.)

For VM-/Storage-Snapshots: no, not possible.

My point is: the integrated backup functionality is completely independent of the underlying filesystem/block device for the virtual disks. It "only" uses the Qemu-integrated snapshot capabilities to get a consistent state.


Unfortunately "Snapshot" is a term with multiple meanings: a PVE-snapshot of a VM, a ZFS-snapshot/LVM-thin-snapshot/.qcow2-snapshot and a Qemu-snapshot are very different beasts.

Agreed. I'm using iSCSI+LVM, and PBS backup works fine.
