Physical Imaging Standard backup sets use deduplication and block-level processing. For these backup sets, the following options are available on the Delete Selection screen:
· Retain backup data for 7 days
· Delete all deduplication data
Retain Backup Data for 7 Days
By selecting the Retain backup data for 7 days check box, you can retain deleted data for deduplication purposes for seven days. At the end of seven days, this data is deleted.
This option is useful if you are using Physical Imaging Standard on this machine and would like to use the existing blocks for de-duplication purposes. At the end of 7 days, this data will be deleted.
Delete All Deduplication Data
By selecting the Delete all deduplication data check box, you can immediately delete any deduplication data not being used. This option forces a block-level cleanup when the delete finishes.
This option is useful if you do not want to use existing blocks for de-duplication purposes anymore and you want to delete them immediately.
Note: You cannot select both check boxes at the same time; selecting one disables the other.
