Current command lines and examples of before and after, both current and desired would help immensely in understanding what it is you are doing and what you want. It sounds to me like you are using rsync every four hours to make backups and you want to use the --backup option to preserve the old versions of the files (what i call decremental backups). At this time the backup files are being replaced the next time the rsync runs and they never get removed. If i understood you correctly the easiest thing to do exactly that would be to specify a --suffix value to rsync that included the date and hour of the backup. --suffix=`date +.BAK.%y%m%d%H` might suffice. Then you could run a nightly script that would find all the .BAK. files and compare their date strings against LAST_MONTH=`date -d "-1 month" +%y%m%d%H` for and rm them. This assumes you aren't using the --backup-dir option which in a way makes this even easier. Unless there is a particular reason for having decrementals you might be better off using --link-dest instead of --backup. Mike Rubel has a writeup (out-of-date? translation available on German wiki) that uses --link-dest for a 1 week rotation but could be made into a 1 month rotation easily enough. You could look into dirvish, there are others using it to do backups every four hours and it does automatic cleanups. -- ________________________________________________________________ J.W.
