Doubt with snapshot storage path

[s3r3ft]

How about, my problem is that I set a snapshot for my folder. But I do not know where the copies are stored, so that in the future I can restore them.

The snapshots are stored within the filesystem. There is a menu option in the GUI for managing them where you can roll back to a snapshot or I think you can mount a snapshot. There is also this that you might want to look at:

You can also list the snapshots from the command line with zfs [I]list[/I] -t snapshot and even though I have not done it with FreeNAS, it should be possible to mount a snapshot from the CLI. I used to do that on Linux when I had a RedHat server running ZoL.

The thing I have had to do most often is mount a snapshot so a user could recover some file that they mistakenly deleted. What a snapshot effectively does is mark the data on disk so that it is not deleted. It is a pretty complex thing. All data blocks in the ZFS pool have a time stamp associated to them and the system can mark them to be retained, even though the user thinks it is deleted, it still exists in the snapshot. I could write about it for longer than I want to spend on this question. Please review some documentation on how ZFS works. The information is out there.

Although ZFS in FreeNAS has diverged from the ZFS that was developed before Oracle bought it, the snapshot system is still comparable.
