MacOS | Scheduling Batches | Minute Increments Possible?

[globalksp]

New to FFS... trying it out as an alternative to Chronosync.

Created a batch and followed the tutorial for scheduling the batch successfully. However, I need a schedule that runs the batch every 5,10,15 minutes and not one a day. Is there a way to use something other than calendar to trigger the sync in MacOS?

Thanks!

Edit: Use case: Photography shoot... throughout the day, images are needing to be backed up to backup drives/locations. Manually starting the sync is an option, but on busy days, it's nice to be able to "set it and forget it". However, for the sake of power efficiency and cpu efficiency, I don't want the sync running continuously every time a file system change is registered (i.e. when a new image is made).
