Most desktops that have a lot of storage have it filled with multimedia, which is highly resistant to data rot, the OS can be reinstalled, this is not a significant issue to most people. > Which would > mean a filesystem that can monitor itself for health and integrity, > down to the individual file level, keep backups and changes, and > repair itself. Which is ZFS. I'm specifically talking about the case where a desktop PC is converted from JBOD to ZFS without any redundancy. > The only real case of 'lose everything' under ZFS is if the disk goes > bad - in which case you'd lose everything under UFS as well, most > likely. When you lose some files from a directory it often renders others worthless, for example losing a third of the episodes of a TV series can be much the same as losing all of them. When a disk fails with UFS, the directories on the other disks are completely unaffected.
