`--keep-time`, `--keep-versions` and `--retention-policy` are part of the backup job configuration.  
They are defined in step 5 of the Add/Edit Backup wizard.  
`--keep-time` and `--keep-versions` can be supplied under “General Options”:

`--retention-policy` is an advanced option.

The `--keep-time`, `--keep-versions` and `--retention-policy` options are applied after completion of each backup job. Compacting is started automatically when needed. You can set thresholds for compacting the advanced options `--small-file-max-count` and `--small-file-size`.
