Storage pool data shredding

Question & Answer


Question

When does the Tivoli Storage Manager server do data shredding on volumes in storage pools with a shred value greater than 0?

Answer

The Tivoli Storage Manager server option SHREDDING specifies whether shredding of deleted data is performed automatically or manually. Automatic shredding occurs automatically as data is deleted. Manual shredding occurs only when the SHRED DATA command is issued.

Automatic shredding shreds data as soon as possible after it is deleted. If the SHREDDING option is not specified, automatic shredding is the default behavior.

Manual shredding allows the administrator to control when shredding occurs in order to ensure that it does not interfere with other server activities.

Shredding applies only to data in storage pools that have been explicitly configured to support shredding.

The SHREDDING option can be set in the Tivoli Storage Manager server options file or with the administrative SETOPT command.
