What methods exist for backing up Xen virtual machine contents? I have some virtual servers running on LVM / Ext4 disks. Preferably a method which can be directly executed over SSH / network connection without the need of creating a local duplicate of virtual machine first.
As far as I am concerned I'd like to back-up the disk image only, not the running state. However, simple copy of the disk partition on-line will probably yield to Ext4 corruption?
