Increases the number of threads performing<br />
deletion of deduplicated chunks which are<br />
no longer referenced.<br />
No effect for nodes which use client-side<br />
deduplication. For those which use serverside<br />
deduplication, storage pool backup<br />
completes before deduplication is applied.<br />
Only files smaller than 100GB are<br />
processed in tier1.<br />
Files in the range 100 - 400GB will be<br />
processed in tier2. Files 400GB and larger<br />
will be processed in tier3.<br />
Controls which file the server device<br />
configuration information is copied to.<br />
A full database backup is only taken once a<br />
day and they are scheduled.<br />
This disables automatic inventory<br />
expiration. Instead, this task is scheduled<br />
to run at a specific time every day.<br />
Allows idle client sessions to remain<br />
through the expected backup window<br />
duration.<br />
Clients which use client-side deduplication<br />
use one additional session.<br />
This option controls the number of volumes<br />
that a process such as a reclamation<br />
process or client restore sessions can hold<br />
open at the same time. A small increase to<br />
this option is recommended, and some trial<br />
and error may be needed. The device class<br />
mount limit parameter was also increased<br />
because of this change.<br />
Limit objects using server-side<br />
deduplication to 500GB<br />
txngroupmax Default: 4096 Allows more client objects per transaction.<br />
