[libvirt-users] Incremental Backups

[Thomas Stein]

Hello.

Another question regarding incremental backups. How can i roll back to a
specific version?

Example.

I have:

1. a base image

-rw-r--r-- 1 qemu qemu 39538851840 Sep 23 11:09 serve.lordcritical.qcow2

2. two external snapshots

-rw------- 1 qemu qemu     1179648 Sep 23 11:17
daily0.serve.lordcritical.qcow2
-rw------- 1 qemu qemu   179175424 Sep 23 14:29
daily1.serve.lordcritical.qcow2

At the moment daily1 is used as the active image.

hn ~ # virsh domblklist serve.lordcritical
Target     Source
------------------------------------------------
vda        /var/lib/libvirt/images/daily1.serve.lordcritical.qcow2

hn ~ #

How do i switch back to daily0? Do i just to have to change the disk
path in the domains xml file and restart? Can i do this somehow live?

thanks and best regards
t.
