IBM revamps data backup

IBM has unveiled the latest edition to its Tivoli Storage Manager data backup and protection software.

Tivoli Storage Manager (TSM) 5.4, released last week, now allows businesses to encrypt data as it is backed up, rather than at the data source.

TSM now also offers companies the ability to digitally shred data when it is no longer required.

"Today, if you erase data, it appears erased, but it's still there. TSM can be set so that if data is erased, the space is overwritten. Administrators can designate a certain set of storage pools as shreddable," John Conner, marketing manager for TSM, was reported as saying.

IBM claimed to have improved application availability by giving businesses the ability to group data into one storage pool, allowing it to be restored faster and decreasing downtime.

The vendor also claimed that TSM 5.4 had deeper integration with other IBM hardware and software products.
