Time Machine with Tahoe

[DavidQPR]

Since updating to 26.2 I have been unable to get a Time Machine backup to complete. On both my MacBook Pro M4 and iMac M3 the backups fail. I have tried dozens of times on both machines. Thinking it must be a failing external drive, which is a few years old, I bought a new 1TB SSD external drive. Same result - it fails every time on both machines.
I have used Time Machine for many years and am at a loss what is going on. Any ideas? Thanks

Are there no error messages? Click the little red circle next to the backup task in TM settings.

Thanks for your reply. I hadn't tried this. Something about a Brave extension. I will have to investigate this. Not sure why it would stop a backup?

 

[DavidQPR]

I have uninstalled the only Brave extension I had, a picture-in-picture extension and am trying the back up again.

It has failed again with a different error. Think I might just give up and use an alternative cloning app.

Do these two files fail on every backup?

Can you view the content of these files in TextEdit? (I don't want to see the content, just whether you can)

What are their permissions and extended attributes? Use ls -le and xattr -l.

The Time Machine Mechanic can help you to extract more detail from the system log.

Thanks for the reply. For now I have removed my external drive from Time Machine and am trying a trial of Carbon Copy Cloner.

Another thought is to run a first aid check on your drive via Disk Utility. Possibly some corruption that is preventing the files from backing up.

Also, you might try excluding the offending files from the backup to see if that helps you get further in the process.

Hi. I did all that before. I have downloaded a months trial of CCC. Successfully did backup of both my MacBook Pro and iMac something that Time Machine seems incapable of doing. Thanks for all replies
