Maintaining available disk space on disk storage units
Disk storage units can be managed so that they do not become entirely full and cause backups to fail.
Create space for more images on a disk storage unit in the following ways:
Add new disk space.
Set the High water mark to a value that best works with the size of backup images in the environment.
Maintain space on basic disk staging storage units in the following ways:
Increase the frequency of the relocation schedule. Or, add resources so that all images can be copied to a final destination storage unit in a timely manner.
Run the nb_updatedssu script.
Upon NetBackup installation or upgrade, the nb_updatedssu script runs. The script deletes the .ds files that were used in previous releases as pointers to relocated data. Relocated data is tracked differently in the current release and the .ds files are no longer necessary. Under some circumstances, a .ds file cannot be deleted upon installation or upgrade. In that case, run the script again:
On Windows: install_path\NetBackup\bin\goodies\nb_updatedssu
On UNIX: /usr/openv/netbackup/bin/goodies/nb_updatedssu
Determine the potential free space.
Monitor disk space by enabling the Check the capacity of disk storage units host property.
This General Server host property determines how often NetBackup checks 6.0 disk storage units for available capacity. Subsequent releases use internal methods to monitor disk space more frequently.
