In NetWare 6.5 SP2 and earlier, Media Manager automatically turned on shredding for deleted snapshots. In NetWare 6.5 SP3 and later, NSS no longer turns on shredding for the internal volume when creating a snapshot. You can apply the system shredding feature to a snapshot pool by entering the following at the NetWare server console:
mm snap shred snapname=on
Replace snapname with the unique name of the pool snapshot. Shredding occurs only in the internal volume of the pool where you are storing the snapshot.
If you turn on snapshot shredding for a snapshot, you can have only one snapshot at a time for a given original pool. When you delete the snapshot, do not create another snapshot until the system has had enough time to complete the shredding process. Depending on the size of the snapshot, allow more time for larger amounts of data to shred. The typical delay time is a few minutes.
If any pool snapshot was created for a pool prior to the NetWare 6.5 SP3 release, shredding is already turned on. You can turn shredding off by entering the following at the NetWare server console:
mm snap shred snapname=off
Replace snapname with the unique name of the pool snapshot. Shredding is turned off only in the internal volume of the pool where you are storing the snapshot. It does not affect other snapshots.
