I backed up, with Time Machine, to this drive, immediately before upgrading to Mountain Lion.

 

Since then: "Time Machine couldn't complete the backup to 'FreeAgent GoFlex Drive'. Unable to complete backup. An error occurred while creating the backup folder."

Since then, this is all I get from Time Machine in the Console:

I don't want to lose all my temporal backup points.

 

I can copy files to and from this drive. The drive is active.

 

Anyone have any ideas? Any more logs I might post?

 

I've scheduled a call with Apple Support this morning so hopefully we'll get some good news. We shouldn't have to lose our old backups because we upraded to Lion, or should we?

    Try removing the backup drive in Sys. Pref. -> Time machine, and then adding back again.

    This shouldn't fdo anything with your existing backups on the backup device, but it may help it "find" the device.

    Likelihood is high that reselecting the backup media in Time Machine preferences (where it appears twice, once as the currently backup and again, with the same name and icon, as a new backup device) will initiate the creation of a new backup sparseimage on the drive and prevent easy access to Time Machine backups through the Time Machine application.

    No.

     

    First, the drive appearing both places was reported as a bug during beta testing; the response was it's "intended behavior." Weird, but it doesn't cause a problem.  See Time Machine - Frequently Asked Question #34.

     

    Second, backups to a directly-connected drive should not be in a sparse bundle; those are used only for network backups.  Do you really have a sparse bundle on the drive?  If so, we'll need to examine it.

     

    Third, re-selecting via TM Preferences will not cause a new set of backups to be started, existing backups to be deleted, or anything of the sort.

     

    Apple did make another change in ML that scares folks, however:  when you eject and reconnect a TM drive, or in some cases reselect it,  the oldest and latest backup dates show "None."  That's just because the display isn't updated until the next backup is completed, but in previous versions, it just showed a couple of dashes (- -).

    Splurben,

     

    I am getting the exact same error message as you. Only difference is my TM disc is a WD MyBook II 2TB disc over a network.

     

    Bought a brand new 15" retina MacBook Pro with Lion installed and TM worked fine over wifi.

     

    Installed ML via the App Store up to date programme, now getting "error occured while creating backup folder"

     

    Only other difference is the TM drive is also used for my main 27" iMac connected via USB. That appears to be working fine, so I know the drive is not damaged.

     

    Thankfully this new Macbook has no work on it yet, so it isn't too much of an inconvienience to start a new backup, but will it keep failing over wifi?

    Update,

     

    Selecting the disc again still fails, with the same error message!

    I've had a similar problem. I've tried deselecting in preferences.  No good.

    The preferences file may be damaged.  Try a "full reset" of TM, per #A4 in Time Machine - Troubleshooting.

     

    Also, a couple of folks have sad a SMC reset worked for them.   Power down, disconect the power cable for five seconds, reconnect and restart.
