Context: I'm going to run Linux file server VMs on VmWare ESXi. Each server will have two virtual disks connected: one for live data, and one for backup (on separate physical hard drives). The plan is to use Rsnapshot to backup the live data onto the backup data disk.
In the past, I've had troubles where files has somehow gotten corrupted, and then the backup of the working files has rolled out of scope in the backup scheme, losing me those files. I'm told that there are file systems that can help me avoid that sort of thing. But which one? For the backups, I'm thinking simply ext4 since it's just rock solid. But for the live data, something like btrfs or zfs sounds good, but I cannot make my mind up about which one, or even if either is what I want. Ideally, I could run some tool once in a while, and if the tool spots corruption, I could just restore the file from backup. Which is best for this out of btrfs or zfs? Or is there a better option?
