WORM Copy is an option that prevents the deletion of data that is not
qualified for aging.
The expiration date for the read-only lock is set to match the data
retention time established in the storage policy copies. These archive
files cannot be modified or deleted by any user or application until the
specified retention date. Once the retention expires, the system deletes
the archives as a part of Data Aging.
Once selected and saved
for a storage policy copy, the following rules are enabled:
WORM Copy cannot be cleared.
Data aging rules cannot be reduced (i.e., made shorter),
ensuring that data can not be deleted earlier than expected.
Data aging rules can be increased (i.e., made longer).
This feature can
be enabled from the
General tab of the Copy Properties
dialog box.
