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.

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

    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.

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

     

    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.
