@Steven Jones I prefer a pure FOSS solution that has good community support.
@Lucas Yamanishi I will check out the links. This weekend I played around with VirtualBox and I was surprised how much script-ability it has. I'd previously only used it in a desktop/GUI context so I was not up to speed on all it's automation features. VirtualBox is a hosted hypervisor but that doesn't bother me. Machines are so powerful these days a little overhead isn't a big deal... plus having a host OS opens up a lot of possibilities. libvirt looks super powerful but there is a lot of overlap with the management tools already in VirtualBox. I might not need anything more. One of the tests I did was exporting the VM and doing a binary delta on it against a previous full backup ( the full backup is basically the pristine VM of the freshly installed and synced replica) . It takes a while to run but the diff packs the backup down quite a bit. It's not a native snapshot but after some though I realized that's not really what I want. The desire is backups with some type of check pointing, to allow for fast recovery and a few fall back options. I would not ever actually use the snapshot since this is just for disaster recovery. The ability to rebuild the VM in it's latest state is the primary goal, the secondary goals being simplicity and frugality of storage use. The nice thing about the scheme is on a minimal install the full backup plus several delta files will easily fit on a DVD. The deltas can be sent offsite easily as they are not very large. Still plenty more research and testing to do but so far this seems like a workable scheme to facilitate "back up everything" without using much storage and in a way I can get my head around. -Aaron On Mon, Aug 13, 2012 at 6:16 PM, Lucas Yamanishi <lyamani...@sesda2.com>wrote: > The libvirt range of tools works very well with KVM, and with > virt-manager, they are easy to setup on the desktop or from a remote > desktop.
