Accessing snapshot file systems

By default, snapshot file systems are mounted in two locations on the file serving nodes:

/

//.

For example, if you take a snapshot of the fs1 file system and name the snapshot fs1_snap1,
it will be mounted at /fs1_snap1 and at /fs1/.fs1_snap1.

X9000 clients must mount the snapshot file system (/) to access the contents
of the snapshot.

NFS and CIFS clients can access the contents of the snapshot through the original file system (such
as /fs1/.fs1_snap1) or they can mount the snapshot file system (in this example, /fs1_snap1).

The following window shows an NFS client browsing the snapshot file system .fs1_snap2 in the
fs1_nfs

file system.
