[bitfolk] Re: Thoughts on disk-image-based backups

In the solution I am proposing for the one customer who asked, BitFolk is going to be in control of how long the LVM snapshot stays around for, so we can keep that burden acceptable. We archive it off and delete the snapshot quite quickly. There is always interest in disk snapshots, so possibly it is worth looking into moving to some other snapshot technology. There is no getting away from the fact that snapshots use storage though, so either the storage used will have to be paid for or the lifetime of the snapshots will have to be limited in some way. Yes it is already possible to overwrite your VM's disk with your own image from the Rescue VM. Of course if there was some disk imaging or snapshots feature then it wouldn't be very hard to have some button in the Panel that restores to it also. Unless using one of the more advanced filesystems, taking a coherent snapshot is something that is not easy for a customer to do themselves, whereas restoring one is, so possibly it is worth focusing on making just the former a feature, rather than the whole bit about storing multiple incrementals. There is a save state command but before looking into this I wanted to see what people's thoughts were. Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
