Selecting Eligible Volumes

The recycler selects volumes for recycling based on the amount of space used by expired archive copies as a percentage of total space on the volume. The volumes with the highest percentages of expired copies are selected to bring the storage usage below the configured High Water Mark threshold.

After the volumes are selected, the recycler determines whether the volumes would gain enough space after recycling to warrant the operation. The recycler determines this by examining the value in the Minimum Gain field either on the Storage Recycling page (for volumes in a library) or in the archive copy (for volumes associated with a policy). If the selected volumes do not meet this criterion, they are not recycled.
