To protect against user error, disk, or total system failure, you can back up and protect all local NTFS volumes, including system/boot, to a local storage destination. The backup agent lets you back up servers, desktops, or laptops as volume-level Physical Imaging locally.
A once-daily backup is the default schedule for a Physical Imaging backup set. You also have the options of creating a recurring interval schedule, or schedule by calendar date and time.
Backups run using the standard calendar scheduler. If a backup runs into its next start time, it finishes and resumes at the next scheduled time. See Backup Schedules for more information.
Requirement: An agent must be installed on each physical machine that needs protection.
Volume capacity limits
When you perform a backup, the Physical Imaging is stored locally, uncompressed, and unencrypted so you must ensure that enough disk space is available. You can also store revisions. See Backup Agent Software Requirements.
The agent cannot back up volumes over two TB on Windows 7, 2008, and 2011.
For newer operating systems (Server 2008 R2/SBS 2011/Server 2012/2012 R2), this limit is 64 TB.
Volume Shadow Copy Service
The Physical Imaging feature uses volume shadow copy service (VSS) to quiesce the system on backup. All VSS writers are involved in this process. Ensure the writers are in a correct state before running a backup.
