file

I would like to run a backup job on a directory tree from a bash script if any of the files have been modified in the last 30 minutes. I think I can hack together something using find with the -ctime flag, but I'm sure there is a standard way to examine a directory for changes.

I know that I can inspect the ctime of the top level directory to see if files were added, but I need to be able to see changes also.

FWIW, I am using duplicity to backup directories to S3.
