    v17 v18  
    1313There are two types of back-up:
    1414
    15 1. Mirror of arsf_data:[[BR]]This is located at ~arsf/backups/arsf_data_mirror/. It is an exact copy of everything under ~arsf/arsf_data/ EXCEPT flights which have been archived with NEODC. If you accidently delete a file in arsf_data while processing, you can come here and retrieve a copy, as long as it was present for the overnight backup. The list of archived flights which are ommitted from the backup is at ~arsf/archived_flights.txt. This is updated as part of the archiving procedure.

    17172. Record of past changes:[[BR]]This is located at ~arsf/backups/rdiff_backup/. It holds a record of changes to small files (anything under 1MB I think). This way, we can recover changes to text files e.g. configs, made weeks or months ago. We can also find out the details of how something was processed by looking at the configs/logs for a given date. The rsync related command `rdiff` is used to create these. Each flight is in a different folder. The past changes are held in ~arsf/backups/rdiff_backup/<flight_dir>/rdiff-backup-data/. To recover the changes, please see documentation on rdiff.
