The name of all groups in your environment that are specified as file system device groups.
The groups that are enabled for staging will be displayed with a corresponding 
.
The groups that are not enabled for staging will be displayed with a corresponding 
.
Lets you enable or disable staging for this device group.
Lets you specify the maximum amount of used space on a disk that Arcserve Backup will use for staging backups. When Arcserve Backup detects that the amount of used disk space exceeds the Max Threshold, Arcserve Backup pauses the backup job and purges the oldest migrated sessions from the FSD until the amount of used disk space is equal to or less than the Purge to Threshold.
Default value: 80%
The Max Threshold can be represented as either the total number of MB or GB used, or as a percentage of the total capacity used on the FSD. If the Max Threshold value is set as a percentage of the capacity of the FSD, the Max Threshold value must be equal to or less than 100% and the Purge to Threshold value must be greater than 0%.
Note: The Max Threshold must be greater than the Purge to Threshold. If you specify an absolute value (for example, MB or GB), the value must be equal to or greater than 1 MB.
Lets Arcserve Backup purge migrated sessions from the FSD when the amount of used disk space exceeds the Max Threshold.
Lets you specify the amount of used space on a disk when Arcserve Backup stops purging the oldest migrated sessions from the disk.
Default value: 60%
The Purge to Threshold is represented using the measurement specified in the Max Threshold (for example, %, MB, or GB). The Purge to Threshold value must be less than the Max Threshold value. If you specify an absolute value (for example, MB or GB), the value must be equal to or greater than 1 MB.
Example: The capacity of an FSD is 100 GB. The amount of used disk space is 75% (75 GB). The Max Threshold is 80% (80 GB) and the Purge to Threshold is 50% (50 GB). The administrator submits a job totalling 10 GB. Arcserve Backup detects that the job, when complete, will be greater than the Max Threshold. Arcserve Backup pauses the job and purges the oldest migrated sessions from the FSD until the amount of used disk space is equal to or less than the Purge to Threshold - in this example, 50% (or 50 GB). Arcserve Backup then continues the backup job.
Note: If Arcserve Backup purges all of the migrated sessions from the disk, but the amount of used exceeds the Purge to Threshold, Arcserve Backup restarts the job and attempts to complete the job using the available disk space.
Lets you specify the maximum number of simultaneous streams to the selected staging group.
Note: Disk staging provides you with the capability of streaming multiple jobs simultaneously to the staging device. You can stream up to 32 jobs simultaneously to the staging device.
Lets you enable or disable SnapLock protection for the selected staging group. To enable SnapLock protection on backup to disk operations, click the Enable SnapLock check box. When you back up data using SnapLock protection, you cannot purge or over-write the backed up data until the specified retention date elapses. The retention time for the enabled SnapLock protection is determined by the specified settings for the staging Purge policies.
Note: The device must support SnapLock technology. If you enable SnapLock on a device that does not support SnapLock WORM (Write Once, Read Many) protection, Arcserve Backup write-protects the data, however, the data can be deleted from the device.
Lets you pause the data migration operation (from the staging device to the final destination media).
