DS-Operator F1 Help for GUI (Context-Sensitive) : Optimize Storage Space Configuration
 
Optimize Storage Space Configuration
The Optimize Storage Space section is only active if the DS-System has been configured to recycle deltas. This increases the speed of backups, but it also increases DS-System storage size until Master reconstruction or optimization.
These options apply for every System Admin process that runs on the DS-System.
 
Optimize Storage Space
Optimize files with at least [...] recycled generations.
Select this check box to enable at the specified number of generations. If this number is “0”, all recycled generations are cleaned.
Optimize files with at least [...] KB recycled generations.
Select this check box to enable at the specified size of generations. If this number is “0”, all recycled generations are cleaned.
Optimize files if last generation older than [...] days.
Select this check box to enable at the specified age of last generation. If this number is “0”, all recycled generations are cleaned.
Optimize files with cumulative delta size at least [...]% of master size.
Select this check box to have DS-System reconstruct delta files only if all the corresponding negative delta generation(s) plus the first positive one (the one that will become master) are bigger than the specified percentage of the negative master generation.
(This reduces situations that require high disk I/O with relatively low space gains.)
