    Hi folks i need some help regarding time machine backups. The problem is it is taking a long time to prepare a backup and then it starts backing up very slowly. it started happening couple of days ago. i am on Yosemite Public Preview 3. Help will be appreciated.

    First TM ever to the TC ?

    If so ... Try doing first backup via ethernet not wifi since the largest backup in the "set" .. every backup after should be quick since TM is only backing up the "changes" said files ..

    I'm having this issue as well, though my last backup was back in July right before I installed PB 1. For mine, I was thinking that it was because of it being a long time since my last backup, but since it has been only a week or so since your last backup, it must be a PB problem.

    Is it possible that installing Yosemite, your partition was changed to be a CoreStorage Volume, which has a unique ID. This unique ID might make TimeMachine think that you are backing up a new machine, thus making a full backup?

    Try reverting your drive from core storage. There are many threads on how to do this.

    I'm having the same issue. It's taking ages by USB 3.0. Seems to be a Yosemite problems. Hopefully it's solved in the next DP or PB
