Backup Script for Mac

I really don’t like working with Mac’s, though the fact that they are based off of unix now does make it easier to work with. A little while back I had to write a script to backup a Mac to a usb drive. I had first looked for some free or low cost software that would backup the Mac and a NAS, but didn’t have a lot of luck. Instead I ended up writing a shell script to do it. It’s a little rough, but works, another note the logging to email isn’t the best, but does work if you enable postfix on the Mac.

here is the script:
