| Archive Rules List | Each item in the list is a separate rule that will be applied in sequence. •	Online files that fall into the scope of the rule will be ‘pushed’ to the BLM Archiver. •	Once files are ‘pushed’, they cannot be restored from the DS-System. They are moved to BLM and can only be written to a BLM Restorable Image if they need to be restored. •	If the last (latest) generation of a file is ‘pushed’, an ‘archive stub’ (a small file containing only metadata) will be left on the DS-System online storage. This prevents that file from being backed up again by the DS-Client, unless the source file is changed. (Note for disambiguation purposes: In all other cases when a generation is archived to BLM, no such archive stub is kept online.) |

| Options | |
| Compare backup time only | By default, a file’s ‘last modified time’ and its ‘backup time’ are both used to determine if it qualifies as ‘old data’. (The oldest of the two times is used.) •	If this option is selected, only the ‘backup time’ of a file is used to determine if it qualifies as ‘old data’. This means files that have not been modified for a long time will remain online until their ‘last backup time’ qualifies them as ‘old data’. | 
| Archive special files (Windows DS‑Client) | [Default is selected.] Special files are the separate items that can be selected when backing up a file system, such as System State or Services Database. •	If selected, the special files in a backup set that qualify as ‘old data’ are allowed to be archived. | 
| Do not archive latest generation of special files (Windows DS‑Client) | [Archive special files must be selected. Default is selected.] If selected, the latest generation of all special files (e.g. System State) is kept online. If not selected, any special files that qualify as ‘old data’ will be archived. •	Select this option if this Retention Rule will be applied to any backup set that is used for Bare Metal Restore (BMR). |
