Re: [Xen-users] Backup domU xen
Hi,
I used these steps to backup my domUs and never I had this problem.

.... seem to be a never ending story ...
I've found the problem of my crashes (two days on a row now).
I'm using lvm2 as a filesystem, and was doing backup's like this:
- take a snapshot of a running system
- mount the snapshot
- rsync the snapshot to my backup-partition.
- umount the snapshot
- remove the snaphost
Have your dom0 enough memory? Snapshots requires some aditional memory,
so if you had your dom0 limited to 256MB of RAM it could be a problem.
To prevent a not responding system you can use "renice" command to
schedule rsync command with low priority.
If you can post more info, like log output of the crash , probably
someone in the list could help you.

This resulted in a huge load, which was increased 1 hour later, and
resulted in a not-responding system.
I googled now for 2 days, and found many discussions, but I cannot
find a proper and stable solution.
Should I maybe just mount the domU over the network (portmap) to have
a non-crashing solution?
Best regards,
Pascal
