“Our DataDomain unit has significantly reduced our backup and restore burden. Tape usage, which previously required weekly manual intervention, is now reduced to an occasional rotation for off-site storage. Even with our wide variety of data, including everything from e-mail to already compressed data sets, we are seeing an aggregate 10x compression ratio. The increased capacity and flexibility our DataDomain unit provides allows us more backup options for our departmental users and has made backups and restores an order of magnitude faster.” — Scott Karlin
