[CentOS] Backing up Xen vm's

Dear All,

because the organization I work for has to enter the 21 century eventually, and encouraged by the the excellent wiki's available, I'm giving Xen a try.

I' ve tested setting it all up but I have this question concerning making backups.

i' ve noticed that virsh snaphot-create does not work, and googling this, I can find many posts describing making backups with rbackup, lvm , dd, ....

The thing is there is not always a date with these posts and articles, so before I dig into this:

Is this still the way this is done, or is there now a more straightforward way to backup ( Xen ) vm's?

Many thanks for any advise.

Greetings, J
