Hi all,

We are planning to use XEN VPS in production environment. Before it we
need to design a realiable backup policy for obvious reasons. I view
two approaches:

a) Use a "snapshot" system for backup ALL VM file (image).
b) Use a traditional backup system (rsync, tar, cpio) for backup
SELECTED data into VM.

I prefer A option but I've read in this list it is not possible unless
you stop de VM during a few time (the time required for backup
operation itself).

If your vm image are files, and use LVM snapshot, you don't need to STOP
the VM for backup.
This thread might help you :
