Removing documents from archive storage
Important: Removing a document from archive storage means
that the backup or long-term copy of the document will be deleted
from the system. You typically remove documents from archive storage
when you no longer have a business or legal requirement to keep them.
A migration policy specifies the criteria that makes
a document eligible for deletion. Documents become eligible for deletion
under the following conditions:
- Administrators delete documents from archive media (using the Remove Report from OnDemand (RMVRPTOND) command)
- An archived document exceeds the time criteria defined in the Expire level of the migration policy (processed by the Start Archived Storage Mgmt (STRASMOND) command) or the Life of Data and Indexes (processed by the Start Disk Storage Management (STRDSMOND) command).
The storage manager does not delete information about expired documents from its database until expiration processing runs. You can run expiration processing either automatically or manually using the STRASMOND command (or you can use the STRDSMOND command with the Run ASM parameter set to *YES). You should make sure that expiration processing runs periodically to allow the archive storage manager to reuse storage space that is occupied by expired documents. When expiration processing runs, the archive storage manager deletes documents from its database. The storage space that these documents occupy then may become reusable.
