Limitations on Performing Raw Backup and Restore Operations

Consider the following limitations when performing a raw backup of physical disks and volumes:

• Arcserve Backup does not support performing raw incremental and differential backups. If you submit such a backup job, Arcserve Backup will automatically change it to a full backup job.
• Arcserve Backup does not execute backups using Volume Shadow Copy Service (VSS) snapshot technology.
• Arcserve Backup does not support the backup and restore of physical disks or physical volumes for clusters. Therefore, these devices will not be displayed under the cluster virtual node in the Source tab of the Backup Manager.
• Arcserve Backup does not support the backup and restore of physical disks or physical volumes for removable media. Therefore, these devices will not be displayed in the Source tab of the Backup Manager.
• Backup jobs may fail when Arcserve Backup cannot obtain exclusive access to the device.
• Backup job fails when you perform a raw backup for Windows 2003, Windows 2008 and Windows Vista environments, if the physical volumes are kept open.
• The physical volumes corresponding to system or boot volumes and the disks on which these physical volumes reside are not displayed in the Source tab of the Backup Manager.
• The Filter option is not available for raw backup and restore of physical disks and volumes.
