[bitfolk] Clonezilla Backup of VPS

Hello all. Just a quick query really. Is it possible to boot Clonezilla or similar on the VPS via the Xen interface? It's not something I know much about, but I wanted a complete and definite way of backing up. I can put the image data to another server somewhere and write to HDD as a complete offsite backup. Clonezilla comes as an ISO, which with Grub2 can be booted, but I don't really want to mess around with Grub too much in case I break it. If there is a better solution to create a complete bit-level backup, fire away. Thanks in advance. George, M1GEO. george-smart.co.uk
