Pending Reclamation — the differencing is complete (duplicate data has been identified) and
space reclamation is now waiting for full cartridges before it can begin.
Partially Reclaimed — in a backup job that spanned multiple cartridges, the full cartridges
have been space reclaimed but the last tape in the spanned set (which is partially full) is waiting
until that tape is full before it can reclaim space.
Dedupe Complete — deduplication, including all space reclamation, is complete for this backup
job.
No Match Found — indicates backups that cannot be deduplicated because they were unable
to match with their previous version due to large-scale modification.
In the detailed Backup and Cartridge reports, the Dedupe Ratio Estimate represents the overall
compression ratio (including both deduplication and compression) of that backup/cartridge based
on the amount of logical backup data stored versus the amount of physical disk space used. If the
backup job status is "Waiting for next backup," "Delta-diff in Progress," or "Pending Reclamation,"
the ratio will only include the compression because deduplication will not have actually space
reclaimed that tape and therefore will not have saved any disk space. If the status is "Partially
Reclaimed" or "Dedupe Complete," the backup disk space has been partially or full reduced by
deduplication and the ratio represents compression plus deduplication. The Dedupe Estimate in
GB follows the same logic.
