    Hello,

    really quick question. I did a clean install of Yosy (Yosemite) and I had an HDD configured to be the time machine with my previous OS X.

    Can I have Yosy recognise the old backups? How do I configure time machine to do so?

    Thanks a bunch.

    Don't know, but why would you want to? As soon as you make a brand new full backup, everything is there. Subsequent backups save anything you've changed, so you're always covered.

    You can search around to find the Terminal commands to reattach your new drive to the old TM backup. But as noted above you can still access your old backups. A consequence of erasing your drive is that from that TM backup's point of view you deleted everything, so it will behave accordingly. You might want to start a new one, since I assume there was a reason for erasing your hard drive. It might even be faster to do a complete new backup than the traversal required for the new one.
