As n subject, is there a safe way to "hot" copy the VMs based on files. The
best is using LVM Snapshot, I guess, but what if I can't for other reason?


You could probably use "xm pause" or "xm save" first, and copy the VM
files then.

Yes, but in that case the VM is not available for the clients. I would looking for the best solution in terms of availability to backup a VM.

Moreover, what does your experience suggest for the copy, just copy using the cp command or better dumping data with dd (like LVM in fact)?

Thanks,
Jan
