HP StoreOnce Backup System Concepts and Configuration Guidelines (BB877-90913, November 2013)

NOTE: If you need to immediately remove data, you must make sure your backup application
is configured correctly. Rotation and retention policies may need to be revisited to ensure that the
data is expired. Also, data that has been written to a store or library without secure erase enabled
will not be able to be securely erased (there is no retroactive application of secure erase to already
written data).
Only chunks that are not referenced by any other items can be securely erased. If a chunk is
referenced by another item which is not marked for secure erase, then that chunk will not be erased,
securely or otherwise. You will need to utilize your backup application when enacting a secure
erase on stores, shares, or libraries that have secure erase enabled.
See the HP StoreOnce Backup system User Guide for information on how to apply the Security
license for these features.
