It would be useful to supply more information about what it is you want to do, but here are some suggestions.
Your best bet would be a custom shell script and the use of the cron facility. Cron will run a script as many times as you ask it to, at regular intervals.
The content of the shell script, which is basically just a series of commands in an executable file, depends on whether you are copying the file to a filesystem destination or another system destination.
This is a sketchy answer, but the question was sparse on details. Hope this helps.
