xen + lvm + backup ?: msg#00145

Subject: |
xen + lvm + backup ? |
Hi,
I wonder how to perform a backup (in Dom0) of several DomU's running in
a Dom0.
fact: a filesystem that is used by a DomU should not be mounted in Dom0
when the DomU is running and accessing it/writing to it. possible
solution would be to shutdown DomU, backup its file systems in Dom0 and
restart DomU.
If the DomU uses devices which are LVM volumes in dom0, a possible
scenario could be:
- create a snapshot in Dom0 of the LVM volume which is used by DomU
- mount the snapshot volume in Dom0
- back it up in Dom0
- unmount & remove the snapshot in Dom0.
could this work ?
regards,
rainer.
