How to Specify a
Disk Image
Section
You can specify a disk image section in two ways. In case of a zero
downtime backup (snapshot or split mirror), you must use the second
way.
• \\.\<drive_letter>, for example: \\.\E:
• \\.\PHYSICALDRIVE#,
where # is the current number of the disk you want to back up.
For example: \\.\PHYSICALDRIVE3
