Bumping, I also would like to know this

DPA 5.8.4 and later releases (including all DPA v6.x releases) includes a report called "Estimated Protected Capacity". You can find this report under Status / Backup in the report menu.

The objective of this report is to attempt to determine the total protected (front-end) capacity of a backup environment. It works by determining the size of the last full backup for each client and it shows totals for filesystem backup and MS-SQL backups. There is also an "Estimated Protected Capacity Details" report which lists protected capacity for each client.

Note that the report only includes the last full backup made in the time period that the report is run over. For example, if you run the report for "last day" but a client did not have a full backup in the last 3 days then that client will not be included. Therefore it is recommended to run the report over a time period of 60 days.

The report was designed for NetWorker, Avamar and Oracle RMAN backups but it is thought that it should also work for NetBackup. Note that while it works when monitoring Oracle RMAN directly, it does not include RMAN backups made within NetWorker.

Hope that helps.

Gareth
