Secure Shred
The Secure Shred page allows you to securely and permanently erase
sensitive data stored on the DXi4701. 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 DXi4701 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 DXi. If necessary, you can cancel secure shred
at any time and return the DXi 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 Figure 209 ).
