Backup Method

The Arcserve Backup Image Option backs up data by taking a snapshot of the drive at a specific point in time. Although the drive appears to be frozen at a particular time, it functions normally and lets other applications send read and write requests. This feature is known as the Snapshot feature, and it is automatically installed when you install the option.

This method has the following advantages:

• At the start of the backup process, the option does not attempt to lock the drive about to be backed up.
• If applications write to the drive while a backup operation is in progress, the integrity of the backup data is maintained at all times. The backup operation continues and is successful even when files are being written to during the backup process.
