Veritas Software and EMC, watch out--Microsoft has officially entered the backup market. After 18 months of development, the Redmond behemoth is beta-testing disk-based backup software called Data Protection Manager (DPM) that should go into general release in the second half of this year. DPM will be priced at less than $1,000 per server (at least initially) and could change the way Windows users back up their data.
DPM will run on Windows Server 2003 and use Microsoft's own Volume Shadow Copy Service to generate backup copies of files, e-mails, and inboxes. It can create four to 64 snapshots of a file or e-mail server per day, depending on the user's (or administrator's) wishes. To save space, the software won't save an entire copy of every file, but retain one original copy and any subsequent changes. To the user, DPM shouldn't look very different from the existing auto-recovery tool that, within Word for instance, provides a list of possible backup versions to restore.
