    So I'm running on out space on my macbook (250 gig ssd) and want to upgrade to El Capitan.

    But I don't want to upgrade what I have, since I'm sure there's tons of junk on that drive I don't want. So I'm making a new 35 gig partition to install El Capitan on.

    Then, I backup my the rest of my hard drive with time machine.

    The plan is once I'm happy with El Capitan, I'd delete the old Yosemite partition, since all the data is backed up in time machine anyway.

    But I'm not sure exactly how that's going to work. Once I delete the old partition, and give El Capitan the whole 250gigs, if I turn on time machine, it will want to delete everything on the backup drive first, right? Or will it recognize those backups from Yosemite, and want to use those?

    It's almost like once I back up Yosemite, I need to partition my backup drive to a Yosemite backup, and an El Capitan backup. Then just copy the few things I want from the yosemite backup manually to my hard drive, and set up the other half of the backup drive as a new time machine backup.

    Does any of that make sense? I feel like I'm missing something here, because it seems awfully convoluted.

    I think you are decided you are going for El Cap and by all accounts its worth it.

    'Notes' seems to be the only major difference for sync with iOS.

    Cant you just archive the files & folders you don't want on the 256 drive to a different backup drive.

    Do a Yosemite backup.

    Then on Wednesday upgrade to El Cap and when required copy back the files you need.?

    Backup your Yosemite partition. When you're ready to delete it and run just 10.11, you can then use Time Machine to copy whatever data you want. If you want to copy apps over then cool.

    I, on the other hand, prefer to just reinstall the apps as that will make sure everything is running nice and clean and just copy over data files I need from Time Machine.
