Cannot back-up to time capsule using Sierra OS

My experience tells me that there is nothing wrong with time capsule. I am trying to back up using USB disk plugged into iMac. I have ticked all the boxes-reformatted, verified, restarted, etc- and cannot back up under Sierra. Back up starts OK, prepares and calculates time to ** OK. Time machine then hangs at about 60 GB. This has happened repeatedly. So I believe problem is with Sierra and not your hardware.

I got the same error message 20 November (my last backup was 19 November). Haven´t had this message earlier and I have had several Time Capsules. This one is a 2TB from a few years back. Working fine until now. Running macOS Sierra v 10.12.2 Beta (16C48b) since 11 November. Have had about 10-15 backups since the Public Beta 2 was installed.

Sorry, but we cannot discuss Beta here....the forum moderators will automatically remove any discussions on that subject.

You are not running any kind of anti-virus application, or any other software that claims to "speed up", "optimize", "keep", "protect", etc your Mac......is that correct?

Just to add to Bob's reply.. if you don't have issues with AV, security software or junk apps.. then this can still happen.

It can be worthwhile to do a verify of your main drive.. although that also has not worked for people.

In the end it is time to opt out of Time Machine and go for a 3rd party backup software.

I use CCC but superduper and chronosync also have following.

Here is one.. failed at 120GB repeatedly. Worked absolutely without issues on CCC.

time capsule fails with error message regsrdingfiles

Hi, I'm having the same problem as discussed here: my Time Capsule doesn't backup my MacBook Air since upgraded to Sierra. I'm running the latest updates, my MacBook Pro works fine with TC. So is there a solution to fix the problem with the automated backup with my Time Capsule?

Tx, Aldert

This thread is getting too long and there are to many different requests from users for help.

Please start a new post for your question.

Thanks!

I too have this problem-no back up on my time capsule.

I have used it for two years.

i started getting the message "no back up for x days.

starting on October 28th-the dayI installed Sierra!.

I have tried several things suggested by members of my Mac Users group.

Nothing.

It starts but does not complete the back up.

As of today I am getting a message no back up for 821 days!!!

has anyone had any success calling Apple?

Possible FIX. I have had the same thing happen to me. I was using the 5gig wireless all along. But that seems to not work in Sierra 10.12.1 So What i did was used the airport utility and changed the admin password then changed my mac to 2.4 gig range wireless and It started the backup again! 🙂 Hopefully this helps some out there!

My connection is wired, I've tried all the posted solutions, I got one successful back up, then back to a constant preparing to back up status. At this point I believe it's a Sierra problem. I'm trailing the Acronis Back Up solution, working great, a ~$40 solution.

Like others, I have done all the right things: reinstalled Sierra, restarted iMac endlessly, removed possibly interfering apps, excluded possibly difficult files and folders, lit a few candles and prayed. Always TM starts, prepares and calculates OK. Then it backs up to validated/repaired/erased/formatted USB drive between 20 and 60 GB and stalls, with little ball spinning endlessly. Interestingly, depending on which files/folders have been excluded from backup, the size of the backup changes, suggesting that there is some file that TM does not like. But of course, I have no way of identifying that file. TM knows but won't tell me. I have given up and am now using 'Mac Backup Guru' which seems to work OK, providing a daily automatic **. I have prepared to downgrade to El Capitan, but it wasn't all that hot either. Also, since installing Sierra, I have changed my email (another nightmare) and accumulated files, settings and apps not backed up under El Capitan. I can't face it.

Hi folks. I have had the same problem as everyone else. However, my research indicates the problem is not with the Airport Time Capsule, but it is with Time Machine. I have discontinued using Time Machine to manage my backups and purchased Carbon Copy Cloner. Carbon Copy Cloner does not have all the functionality of Time Machine, but it backs things up to my Airport Time Capsule. Apple needs to update Time Machine so it is compatible with Sierra.

Sorry, this doesn't work, I tried ...
