 To do so it is using the following independent variables:
 
-* BACKUP_KEEP_MINS: will remove files from the `last` folder that are older than its value in minutes after a new successfull backup without affecting the rest of the backups (because they are hard links).
-* BACKUP_KEEP_DAYS: will remove files from the `daily` folder that are older than its value in days after a new successfull backup.
-* BACKUP_KEEP_WEEKS: will remove files from the `weekly` folder that are older than its value in weeks after a new successfull backup (remember that it starts counting from the end of each week not the beggining).
