With the appropriate access credentials and permissions, NFS and SMB users can view and recover data from OneFS snapshots. The snapshots are accessed through the ‘.snapshot’ directory, as described previously in this paper. The following screenshot from a Windows client shows the list of snapshots available on a OneFS SMB share:
In the example below, a user accidentally deletes a file ‘/ifs/data/foo/bar.txt’ at 9.10am and notices it is gone a couple of minutes later. By accessing the 9am snapshot, the user can recover the deleted file themselves at 9.14am, by copying it directly from the snapshot directory ‘/ifs/data/foo/.snapshot./0900_snap/bar.txt’ back to its original location at ‘/ifs/data/foo/bar.txt’.
SnapshotIQ integration with Windows Volume Snapshot Manager allows Windows users a simple way to restore data on a cluster’s SMB share from the “Previous Versions” tab on their desktop.
