14.4 Space Reclamation
The Space Reclamation page allows you to manage space reclamation activity on the
ETERNUS CS800. You can start or stop space reclamation. You can also monitor the
progress of space reclamation activity.
During space reclamation, the ETERNUS CS800 searches the blockpool for tags that are no
longer referenced and then deletes the unneeded tags to free up space.
In addition, the ETERNUS CS800 automatically compacts reclaimable space in the
following ways:
l During data ingest, reclaimable space is compacted as needed to provide space for new,
deduplicated data.
l If the ETERNUS CS800 is not in Low Space state, compaction starts when used disk
space reaches a high level and there is sufficient reclaimable space. Compaction stops
when used disk space falls below the high threshold state. The reclaimed space can be
used to store new deduplicated or non-deduplicated data.
l If the ETERNUS CS800 is in Low Space state, compaction starts and continues to run
until the ETERNUS CS800 exits Low Space state. The reclaimed space can be used to
store new deduplicated or non-deduplicated data.
