—Idealstor has added continuous data protection (CDP) for Windows servers to the 4.0 version of its Ibac data-protection software. Released today, Ibac 4.0 continuously backs up systems at the byte level and allows users to recover lost or corrupted data from any point in time.
Ibac performs an initial backup and then stores only changes to the data. The data is stored in its native format using DESX or 3DES encryption at up to 10GB per minute, according to Idealstor officials. Restores are also quicker because files can be restored by name or accessed directly from the backup server. Ibac also performs bare-metal restores.
"Unlike replication, where corruption happens on both the source and target, with CDP users can roll back to just before a corruption in order to restore data," says Ben Ginster, channel marketing manager for Idealstor.
Using the change logs in Windows applications such as Exchange and SQL, the 4.0 version of Ibac allows users to back up to any point in time, even for open files. This lets users restore to a state prior to data loss or corruption.
By employing two separate modules, Ibac 4.0 gives users the ability to choose which applications will be protected by CDP. The software can separate regular scheduled backups from continuous backup. Users can assign more critical servers to CDP and less-critical servers to backups on a scheduled basis.
The software operates with Idealstor's backup appliances—including the FrankeNAS, Idealstor Backup Appliance, and Idealstor SATA—as well as any other Windows server appliance with enough capacity to store the backed up data.
Ibac can also operate with ejectable disk media, which Idealstor offers, allowing media to be taken off-site as with tape storage.
For small branch offices that back up over a WAN, Ibac's recording of byte-level changes uses a small amount of bandwidth at a continuous pace rather than slowing down the system during a scheduled backup window.
Ibac 4.0 is sold in pairs at a cost of $1,500 each for the source and target.
