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

this is not a problem for Apple, we have already bought our TMs and they are likely out of warranty

It nukes your whole filesystem.

It doesn't nuke your whole filesystem. It nukes your entire backup. Huge difference.

If you are a developer or have access to bugreport.apple.com file a bug report. That's the only way something is going to be done. Apple doesn't monitor these forums for bugs.

You state the same questions I have.

I have a Time Capsule (not a NAS) that has been working for 2 years with TM. Recently I have been getting the dreaded message: "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you."

I have already told TM twice to just redo the whole backup. I also tried some forums suggestions to verify/check the backup, but I wasn't able to correct the problem (it did confirm errors in the sparse bundle).

Yesterday I have my third time. Now I have manually deleted the old backup first from my Time Capsule and also restarted the Time Capsule twice via Airport Utility, hoping this would trigger a disk check by the internal OS. Another resort I am thinking of is filling the hard drive with a dummy file to see if that can at least trigger some kind of disk check.

If the disk is faulty, then it would be 'nice' of the Time Capsule to tell me. Then I can replace it. Without such a warning I hesitate to open a Time Capsule, since there's always a chance  that in the process I scratch or damage it.

Did anyone with a TC and TM ever solve the problem? Meaning that the message did not return anymore?

This happened to me yesterday for what seems like the twentieth time in about five years with three different NAS operating systems. I had only just re-installed the OS on a new drive on my Mac and created a new Time Machine backup two weeks ago.

I'm sick of it. And I'm sick of all the Apple apologists who keep blaming the NAS manufacturers. Time Machine reads and writes data - whether it is over a network or via USB ought to be immaterial in this, the second decade of WiFi. But no, Apple wants to play the proprietary technology card when just about everything else in the computer world which has matching male and female connectors works; HDDs, SSDs, RAM, monitors, keyboards, memory sticks etc. It reminds me of the old story of a mother at her son's passing out parade, proudly boasting that her son was the only one in step.

It might not be so bad if the Time Capsules which Apple produce had any other functionality; they surely persist with the one trick pony out of spite for all the NAS manufacturers whose products can do just about anything asked of them.

Well, as might be guessed from my avatar, I have been using Macs since 1984 and for the past few years, I have noticed that the newer versions of OS X have added very little to my needs and as a result, I have all the functionality I anticipate needing, the software I use is compatible and also sufficient for my needs; I am going to end my Mac journey with Yosemite and dump Time Machine for Carbon Copy Cloner. It may not have the Star Wars appearance but if it doesn't give me Orwellian messages of dread every few weeks or months, I will live with that.

This happened to me with a brand new 2TB TimeCapsule - less than 4 months old - with my 2015 Macbook, so it isn't like Apple's own hardware works right in this regard.

Very frustrating as it took nearly a week to rebuild it and that was leaving my Macbook plugged in and on far FAR more than I normally would.

Pure Mac system: Mac laptops running most recent OSX, and a 3TB Time Capsule installed two months ago.

Rather unhappy that all my old backups appear to be gone, since there did not seem to be any other alternative

given in the popup window to "Create New Backup".

very frustrating. TM works great with my WD 2TB Passport connected by USB to my Macbook Pro 2016. But could not complete one clean backup over home wifi network to a WD 4TB MyCloud drive. Keeps getting a note requesting to delete and restart a new backup. Trying last time before just ignoring the option of over the wifi backup to cloud.

I'm amazed that this still is an issue. I've experienced this bug for many years now.

What upsets me most is that at the point you start a new backup, Apple deletes your old backup. Yes, Apple actively removes a layer of redundancy so the only available backup is the device being backed-up. If the device being backed-up fails during this critical first backup, you lose all your data.

This is the very antithesis of a backup strategy, and is the reason I moved to a NAS from a TimeMachine- so every time this happens I can make a backup of the backup Apple is about to delete permanently!

What should it do if there is insufficient disk space, nothing?

Very frustrating. TM works great with my WD 2TB Passport connected by USB to my Macbook Pro 2016.  I finally managed to complete a full TM backup volume 260GB on my 4TB Wd MyCloud! it kept adding ok for 3 days but after disconnecting the Macbook from the network - when I reconnected at home - and tried to do a daily backup - got the bad news - need to verify - begin a new backup thus deleting my 260GB backup file.

so I am lucky to have a few  backups:

1. on a USB connected WD Passport,
2. as well as Crash Plan -
3. and I am also using GoodSync Pro software I bought - so likely to forget and dump the TM and its over the network backup attempts.

I so much share and identify with Csound1 and others here.

I had this same issue.  I did not want to loose my Time Machine backup(s).  After some research online I found this link http://jd-powered.net/notes/fixing-your-time-machine-backup, which I followed and successfully reestablished my Time Machine backup.

Just a follow up to my last post.  My Time Machine backups are still working a week later.  I have not had a repeat of the issue.  All is good

TThat's is I give up on TM over the network wifi or Ethernet cable to my WD 4 TB disk!

finished 240GB and then - had to remove message!!!

i Do only USB hard connected to a 2TB Passport drive.

UPSET .

Thanks,

Hanani

Well, this is disheartening. The original post is from 4 years ago and it looks like it is still a problem.

Just received the same error message regarding the TM backups to my Synology DS415+ after 2 months of successful backups.
