I've been wanting to continually back up some files with time machine for a little while now, mainly just my music collection and word documents. The problem is, my iMac's HD is 500GB (and nearly full) and the biggest external drive I have is 250 GB. I only want to continually back up a few files and would prefer not to buy a brand new hard drive, so my question is this: Is it possible to use time machine to only back up a few specific folders and not my entire computer? I've looked into it and all I've found anyone saying is that I can back up the entire computer and then choose a few files to exclude in the back up instead of just backing up a few files period. Also, I am wondering if it is possible to avoid the initial backup of the entire computer, as my 250 GB drive is obviously not up to the job. I hope that made some semblance of sense. Any and all feedback is appreciated, thanks!
