Resolution

SOLUTION

Creating a snapshot using DD OS 5.0 and later
  1. At the Data Domain system prompt, type: 
    snapshot create <snapshot> mtree <mtree-path> [retention {<date> | <period>}]
    Example: 
    # snapshot create test22 mtree /backup retention  1mos
Snapshot "test22" created and will be retained until May 31 2010 08:48.
    • If a snapshot was created at 8:48 a.m. on May 1, 2010 with a retention period of one month, it would be retained for 30 days.
    Note: The maximum number of snapshots allowed to be stored on a system is 750. If the maximum number is reached, the system generates an alert. You can resolve this by expiring snapshots and then running the command filesys clean.
