in reply to Delete all but the most recent backup file

Any ideas on if a backup has not been created in past 24hrs that the most recent backup is kept and the rest are deleted?

So you need to check, whether the backup file created within the 24 hours first, if so, then delete all the backup files which are older than 24 hours

To find the files created withing 24 hours try this,

if (1 > -M $filename) { # Your code goes here }

If any files found then do your normal delete (deletes backups that are older than 24 hours) or skip the deletion part.
