Q: Time Machine backup very slow in Lion

After installing Lion Time Machine backup (not initial one which is long by default) takes about 40 minutes vs. about 5 minutes in Snow Leopard. Very annoying because it slows down my entire system for such a long time. Any help, please?

Mac mini, Mac OS X (10.7)

    I think it is due to the fact that it is the first initial backup from lion as opposed to snow leopard...give it a little time, the speed should improve with the second backup...let me know

    Hello;

     

    As Jack said, the first one after the move to OS X 10.7 takes quite awhile - a lot changed.  After that, the backups are "normal."

    I gave up on Time Machine until this evening. It seemed that everything just froze. So I'll let it run all night and see what happens.

    As mentioned in my first post it is not the initial backup but second, third etc. Same type of backup took only about 5 minutes in SL.

    Has Spotlight finished indexing all your drives (see if there's a tiny dot in the icon at the right of your menubar)?

     

    If not, that's at least part of the problem.

     

    If it has finished, try a Restart.

    Yes, Spotlight finished indexing and I also restarted computer twice. Used Coctail to perform all the maintenance routine procedures (cleaning caches, repairing permissions etc.).

    I'm having the exact same issue. But I figured out that Time Machine is always backing up over 30GB of data per hour.

     

    That's obviously not right, I don't change all that data in a one-hour period.

     

    With Snow Leopard the hourly backups didn't get past 200MB of data each.

    Oops, my bad. I do use VMware Fusion, and the virtual HD file indeed is over 30GB.

     

    Thanks a lot for pointing me to the obvious (no sarcasm)!

    Here is a log copied from Time Machine Buddy:

     

    Starting standard backup

    Backing up to: /Volumes/Time Machine/Backups.backupdb

    2.20 GB required (including padding), 126.68 GB available

    Copied 394 files (0 bytes) from volume Pete 02.

    Copied 173985 files (861.6 MB) from volume Pete 01.

    1.13 GB required (including padding), 125.79 GB available

    Copied 13 files (0 bytes) from volume Pete 02.

    Copied 158965 files (90 KB) from volume Pete 01.

    Starting post-backup thinning

    No post-back up thinning needed: no expired backups exist

    Backup completed successfully.

     

    No additional messages, perfect backup, no need for thinning and it took 45 minutes, almost 10 times slower then in Snow Leopard (same TM preferences, exclusions etc).

    Are either of the volumes being backed-up an SSD?

     

    Nothing in the green box helped, especially anti-virus?

    No, I'm not on SSD yet. I don't use anti-virus.

    Generally - all my configurations are exactly the same as in Snow Leopard the day befor Lion upgrade so I think the problem is on Lion's side but I can't figur out where.

    Now I'm observing Time Machine preferences window while performing backup - extremely slow and it runs twice (!?) - first about 350 MB and then about 1,2 MB but also very slow comparing to previous system.
