Unless the drive gets corrupted or infected with malware, you can just load a previous snapshot. That's much faster and easier than reinstalling.
Snapshot as in a VM?
Most people run their OS on physical hardware.
You can run your desktop inside of a VM with the GPU and USB PCIe devices passed though.
However, I think they are talking about btrfs
Btrfs has snapshots. They can be created instantly and don't use any extra space until the files are changed.
Ah, yeah, I have read about that, I do feel a bir hesitant to use BTRFS so I didn't think about that.
The Linux machines I have worked with all ran ext3/4 or xfs.
To be completely fair, I never gave BTRFS a proper chance, at first because it felt too new and unstable when I heard about it, and later I heard that it was developed by Facebook and let my distaste for that company color my perceptions of btrfs.
But I just checked the wikipedia article and saw that plenty of reputable oranizations have worked on btrfs, so I guess I'll get it a go when I build a NAS....
Thanks for reminding me of it, I may get set in my ways from time to time but I do genuinely try to learn and change my way of thinking.
I wouldn't use it for a NAS. You want ZFS for that.
Btrfs is good for small setups with either single or dual disks.
Just don't use RAID 5 or 6, it's still under development and not ready for use yet.
