Configuring the free disk space threshold for backups
About this task
Set a threshold for free disk space that must be available before a backup operation can start. Ensuring that there is sufficient free disk space helps to prevent backup failures.

Click the Configure link for the Disk Space Threshold feature.
The Configure Disk Space Threshold dialog appears.
-
Select Do not backup if free space is below % and enter the percentage of free space that must be available before a backup operation can start.

If a backup is attempted when the free disk space is below the configured threshold, the backup fails and an Error dialog displays the free disk space for each node.
