I got an error today from TimeMachine when it was trying to backup my MBP (10.6.8):

 

"Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you. Click Start New Backup to create a new backup. THIS WILL REMOVE YOUR EXISTING BACKUP HISTORY."

 

This sounds pretty nasty.

 

I back up over WiFi to a Western Digital MyBook Live.


MacBook Pro, Mac OS X (10.6.7), Intel Core 2 Duo 2.26GHz 8GB RAM

    This vexing problem is almost guaranteed to occur for this reason:

     

    I back up over WiFi to a Western Digital MyBook Live.

     

    That's the problem.

     

    Read: Mac Basics: Time Machine

     

    Apple offers specific guidance regarding what devices Time Machine can use, as well as specific guidance regarding what it cannot use. Everything else lies in the great unknown, including NAS devices and wireless ones in particular.

     

    For a more thorough analysis of this problem, and potential remedies, read Apple Support Communities contributor Pondini's discussion here:

     

    "… Time Machine must create a new backup for you."

     

    Read the pink box.

     

    Just bear in mind your particular Time Machine installation is not one specifically supported by Apple. You're on your own doing anything that is not. Given the "mission profile" of a backup strategy you should use a supported method. An unreliable backup plan is almost worse than none at all.

    Back a month later. I tired a recommended fix I found online which is just a hassle requiring going into Terminal as root and tweaking files.

     

    It saved my bacon a month ago but then last week I got the error again, so I did the same procedue and all was well. Today I got the error again.

     

    OK, now I'm tired of having to fix this. Will switching to a Time Capsule banish the error once and for all?

    ds store,

     

    I understand all that. I'm an EE who has been designing computer and network devices for 30 years. I'm asking specifically if using a Time Capsule will get rid of these backup corruption problems I'm getting with the WD drive.

     

    I'm having my wife back up her MacBook Air to that drive because I could never get her in the habit of backing up to the hard drive I gave her. God forbid I have to fix a corrupted backup for her.

     

    The FW800 hard drive I used before going to a networked drive is still in action backing up an iMac and I'll go back to that one myself for the time being.

     

    Thx for the reply.

    You will encounter this problem again and again until you use a backup method supported by Time Machine. They are as follows: a Time Capsule, and a locally connected volume such as the FW800 one you are using.

     

    Anything other than those two options will be unreliable.

    OK, thanks.

     

    Guess I'll get myself a Time Capsule then.
