Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.

This is the error I am receiving.

Click Start New Backup to create a new backup. This will remove your existing backup history. This could take several hours.

Click Back Up Later to be reminded tomorrow. Time Machine won’t perform backups during this time.

Can anyone tell me why? The last back up was July24th. I am afraid to start a new back up if I have to erase everything first.

My Mac OS X version is 10.7.4

Need help with this, as I am very confused why it stopped working.

Time Capsule 802.11n (4th Gen), Mac OS X (10.7.4)

Did something change just before that? Upgrade to Sierra, new devices on network, ...

It's doing the same for me, I thought the Time Machine Hard Drive was on the way out so purchased a new 2TB one which does exactly the same. I'm uninstalling some bits and pieces as mentioned above to see if that helps.

Dec 12, 2016 2:52 AM in response to July7Kiss1995

After getting this message daily for over a week I contacted Apple support. They recommended I do a "Soft " Reset" of the Time Capsule. That seems to have worked as I haven't had the message since (over 1 week).

I have just noted an issue with my NAS backup using TimeMachine. Has anyone noticed data corruption of any of their drives or incremental backups just after installation of the Advanced Meter from the Gas Company, (in our case Southern California Gas)?

This occured just after the installation of the meter and the NAS is within 10 feet of where the smart meter is.

Not sure exactly what this had to do with anything, but just in case, you should never use any anti-malware software to quarantine or remove a file from any type of backup volume as it will almost certainly result in corruption.

ClamXav actually recommends against scanning your Time Machine / Time Capsule or other backup as it will simply take too long. For each and every backup on there, every file appears to be different even if they're identical, so the same files end up getting scanned over and over again.

It also provides only minimal protection as it's not possible to remove any malware that ClamXav finds - the only software that can modify a Time Machine/Time Capsule backup is Apple's Time Machine software itself.

The best course of action would be to scan your hard drive now, to remove any malware which might currently be present meaning that any infected files on your Time Machine/Time Capsule backups will simply get deleted in due course as your backup disk runs out of space. It may also be worth running a scan over your computer at a later stage if you ever have to recover it from backup.

Dec 17, 2016 8:04 AM in response to July7Kiss1995

Still no luck here. My other two computers have been and are still backing up fine to the Airport Extreme 3tb; my one computer still produces the same thing. I have attempted multiple avenues of deleting app just to see to no avail. I wish apple would do something about this. Considering how i no longer have any back ups of this computer and everyone I create a new backup, it crashes and produces the same verification error about once every 2 days.
