9.4 Clearing Backups

Coot will occasionally ask you to clear up the coot-backup directory. You can adjust the behaviour in a number of ways:

• (define *clear-out-backup-run-n-days* 3) will run the backup clearance every 3 days (the default is every 7).
• (define *clear-out-backup-old-days* 1) will clear out files older then 1 day (rather than the default 7 days).
• You can create your own version of the function that is run on exiting Coot: (clear-backups-maybe)

So, if you wanted to clear out everything more than 1 day old, every time, without Coot asking you about it:

     (define *clear-out-backup-run-n-days* 0)
     (define *clear-out-backup-old-days* 1)
     (define (clear-backups-maybe)
       (delete-coot-backup-files 'delete)
       (coot-real-exit 0))
