Backups on OpenVZ / KVM
Currently I have been spoiled by proxmox and its prebuilt backup solution. I was curious if there was anything similar for hosted KVM / OpenVZ server that will give you a full backup including the OS. With the possible bonus of being quickly sent to a provider for them to deploy back into service if another provider died.
Thanks for your help!

KVM - R1Soft
OpenVZ - Duply? (not ideal solution for OVZ but has bailed me out of the proverbial a few times)
correctly me if I'm wrong but any full backup including os will not work with every cp as proxmox uses qcow2 file sys, whereas say solusvm lvm, etc. etc.
What's wrong with r1soft and OVZ? @MarkTurner
Doesn't work, R1Soft requires access to a block device and load a kernel module. OpenVZ can not do that.
I wish there was something that could be easily imported into other providers.
I'll check out duply, thanks @MarkTurner
you could however, generate ovz archive manually or with a bash script and backup via r1soft
OpenVZ is easy. Just use vzdump. It's simple and just works.
KVM not quite so easy like everything else with KVM. It's best if the guests are set up as LVM volume groups so that you can do a snapshot. Secondly I believe you gotta do block level which is quite primitive. Either that or a 3rd party solution that some others here have suggested.
I can't vzdump. These are on providers, not self hosted. In trying to find a good way to backup the servers that can be easily transferred .
Quick and guaranteed restores seem to the problem on openvz.
I'm setting up rsnapshot for pull backups of openvz filesystems. At least I'll have the raw files.
I've had to ask them in the past, if you're backing up regularly I don't they'll honor the request each time.
I hope you find something, I'm also interested.
Duplicity. Should be capable of making a full-system backup.
EDIT: Removed as vimalware already mentioned rsnapshot above.
