Optimizing master generations
This feature allows you to try to reduce space occupied by master generations.
To optimize at the individual backup file-level:
1. In the Storage Info for dialog box, select the master generation you want to optimize.
2. Click Optimize.
• DS-System will try to optimize the master at the block-level (it may achieve slightly better de-duplication than the DS-Client).
• If the preceding generation is also a master, DS-System will convert the master you are optimizing into a delta that depends on it.
To optimize an entire backup set:
1. In the Customers tab, browse to the customer, DS-Client, and select the backup set you want to view.
2. Right-click, and select Run Master/Delta Optimize. The Master/Delta Optimization process starts immediately.
• By default, the DS-System will try to optimize the backup set’s master files at the block-level (it may achieve slightly better de-duplication than the DS-Client). It will also convert back-to-back masters into the master-delta chain (where appropriate).
• Additional optimization depends on the setting of the
FixDeltaChain advanced configuration parameter. This will convert a delta generation into a master when the DS-System detects the delta chain is too long, For more information, see:
“Configuring the advanced settings”.
