2. To optimize files with a specific number of recycled generations, select the Optimize files with at least [...] recycled generations check box, and then enter the number of generations. If the value is 0, all recycled generations are cleaned.

3. To optimize files with recycled generations of a specific size, select the Optimize files with at least [...] KB recycled generations check box, and then enter the size in KB. If the value is 0, all recycled generations are cleaned.

4. To optimize files if the last generation is older than a specific number of days, select the Optimize files if last generation older than [...] days check box, and then enter the number of days. If the value is 0, all recycled generations are cleaned.

5. To optimize files whose cumulative delta size is a minimum percentage of the master size, select the Optimize files with cumulative delta size at least [...]% of master size check box, and then enter a percentage. The DS-System will reconstruct delta files only if all the corresponding negative delta generation(s) plus the first positive one (the one that will become master) are larger than the specified percentage of the negative master generation.
