Arcserve Backup allows you to back up your data either to rewriteable media or WORM media. WORM media, with significantly longer shelf life than magnetic media, manifests secure, long-term storage for data you do not want to erase.
Arcserve Backup lets you mix WORM and non-WORM media in a library. From the Device Manager, you can identify WORM media by an icon with the letter "W" inside a red circle. In addition, Arcserve Backup lets you specify WORM media for custom backup jobs.
