Clients backed up with multiple streams
When a client is backed up by multiple streams, the client's size is equal to the total of all backup images that were created by all streams. Job throttles on the policy, the client, and the storage unit hinder the utility's ability to group the streams with certainty. For example, instead of starting within minutes of one another a subset of the backup streams may start in a different day than the rest of the backup streams. Because the utility sums only the backup images from streams that originate within the same 24 hour period (midnight to midnight), these streams are counted in separate days. Manually initiating a second full backup within the same day also skews the results. Streams from both backups are counted together as a group.
