Library Summary

Use this window to display a summary of the disk library.

General

This section displays the following information:

• The status of the library and, if not operational, the failure reason and since when it has not been operational
• The library type (disk)
• Total capacity freed in the library in the previous week

  NOTES

  The free capacity on a disk library will not be updated until Archive Pruning is performed. When a Storage Policy or a backup set is deleted, the capacity freed by these entities will not be displayed until Archive Pruning is performed.

• Total amount of data written to the library in the previous week
• Total capacity available in the library

  NOTES

  Capacity available is calculated using the total amount of free space available on all of the mount paths configured for the library.

Mount Paths

This section provides important information on the mount path configured for the library. This includes the following:

• The mount path
• Whether the mount path is operational and, if not operational, the failure reason and since when it has not been operational
• Total capacity available in the mount path

Library Utilization

This section provides the trend for the amount of data written and read in the library over a period of time, using the Activity Qualifier Window, which is based on the settings in the Cell Configuration (Data Protection Window). This data can be viewed using daily, weekly, or monthly frequency based on the selected frequency period.

This section will help you to determine if there is a sudden growth or fall in the amount of data being written to the library for the selected frequency period.

Space Utilization

This section provides the trend on the amount of space being consumed and freed within the library over a period of time, using the Activity Qualifier Window, which is based on the settings in the Cell Configuration (Data Protection Window). This data can be viewed using daily, weekly, or monthly frequency based on the selected frequency period.

This section will help you to predict the total space requirements for the library.
