Commvault Turns Snapshots Into 'Proper' Backups

March 21, 2011 09:00 AM

As we discussed a few weeks ago, you can certainly argue that snapshots, when combined with replication, could serve as an adequate backup system. My biggest objection was that snapshots lack the catalog that conventional backup applications build as they back up data. Commvault's SnapProtect fills that gap by providing catalogs and a management console for snapshots across a variety of arrays and other snapshot providers.

With conventional backups, an administrator, after cursing under his breath and wishing he could just say no to the CFO, could search the catalog database for *smith*.xls in Finance and locate the file. Since local snapshots don't include catalogs, it's harder to restore the data that disappeared sometime last summer. But there are more issues around using local snapshots for backup.

Last week EMC blogger Chuck Hollis started a bit of a firestorm when he questioned the marketing position some vendors are taking that local snapshots make traditional backups unnecessary. As we could expect, a series of EMC haters, employees of other vendors and industry analysts jumped in to add fuel to the fire. I think Hollis did ask a valid question: As technologies advance, what is a backup?
