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

****, ****, ****!!! since I got my new 2020 MB Air, with Catalina, 2 weeks ago, I've gotten this message, and problem, twice. My Time Machine is an Apple Time Capsule which has worked fine up til now. The first time I simply did it, and only after found I'd lost 2 years' worth of backups. Now, less than 2 weeks later, I just got the same message again.

I've looked all over the internet, including here, only to find that this happens, Apple has apparently been aware of it for years but not fixed it, and no one seems to know any solution. The only half-solution is making another backup to a separate external disk, which I do with SuperDuper clones, but past stuff is still lost.

Does anybody have any newer news about this, maybe even a real solution, or is Time Machine essentially dead now?

MacBook Air 13″, macOS 10.15

Time Machine backups to a network drive......like a Time Capsule......are simply no longer reliable with Catalina.

Time Machine backups to a local drive, like a USB drive connected directly to your Mac are fine. So, if you want to continue using Time Machine, that would be the way to set things up.

Use the Time Capsule as a router or a spare hard drive to store regular data......not Time Machine backups.

Things will change with Time Machine in the next operating system, but there is no way to know whether Time Machine will improve at this point.

Thanks, Bob, that's what I was afraid of. At least I can stop trying to fix it. This sort of thing, along with much more over the last few years should prompt Apple to revise their old motto. It should now be "It just works - maybe."

For what it's worth, I have been using Carbon Copy Cloner (CCC) to back up to a Time Capsule with 2 Macs and things have been flawless for the last few years since I started this as an additional backup plan.

I have no interest in CCC other than that as a satisfied customer.
