DB ASE 16.0 Housekeeping old backup files

Estimates

I am looking for a procedure to delete old backup files, my idea is to have five full database backups along with their logs at most. I was reading the guides (system administrator guide vol1 and vol2) without much success and I can't find a procedure to clean these files.

I think the closest thing to cleanup in my environment would be to run a cron with the command find plus rm of the files found with a certain age, but I find that the solution is not the most elegant.

My ASE database is from a solution manager and is in version 16

Thank you for your answers
