Using ZFS snapshots

Snapshots are copies of a ZFS filesystem, taken once an hour. There are 24 snapshots

taken before old ones are removed so basically a days worth of snapshots. Should you loose

or corrupt a file in your ZFS directory, you can go to a snapshot to retrieve a previous

version of the file.

To see your snapshots go to the directory /<filesystem>/.zfs/snapshot, then to one of the

subdirectories. /home/pier/a/.zfs/snapshot for example. Each subdirectory is named by the

time of day it was taken.

The files are preserved in permission and ownership so the user can restore whatever version

of the file they want. They are only able to see and or copy whatever they could see an or copy

when the snapshot was taken of the filesystem.
