SAN hardware snapshots
This option is effective for backups of VMware ESXi virtual machines.
The preset is: Disabled.
This option determines whether to use the SAN snapshots when performing a backup.
If this option is disabled, the virtual disk content will be read from a VMware snapshot. The snapshot will be kept for the whole duration of the backup.
If this option is enabled, the virtual disk content will be read from a SAN snapshot. A VMware snapshot will be created and kept briefly, to bring the virtual disks into a consistent state. If reading from a SAN snapshot is not possible, the backup will fail.
Prior to enabling this option, please check and carry out the requirements listed in "Using SAN hardware snapshots".
