14.5 Secure Shred
The Secure Shred page allows you to securely and permanently erase sensitive data stored
on the ETERNUS CS800. To securely erase data, first delete files on NAS shares or storage
servers, or erase tape cartridges on VTL partitions, then start secure shred. During secure
shred, all residual data associated with the deleted files or cartridges is securely erased from
the disk drives by performing a single-pass overwrite with zeros.
While secure shred is running, the ETERNUS CS800 operates in limited mode. This means
you cannot perform backups or restores, all scheduled jobs (including replication jobs) are
stopped, and you cannot access or use any other features of the ETERNUS CS800. If
necessary, you can cancel secure shred at any time and return the ETERNUS CS800 to
normal operation.
CAUTION!
The secure shred process can take multiple days to complete.
To access the Secure Shred page, click the Utilities menu, and then click the Secure
Shred tab (see "Secure Shred Page" on page 453 ).
