Time Machine...

Since updating to Sequoia B3, my Time Machine backups have been failing, but ONLY when my Mac Studio is in "Sleep Mode" and has put the hard disk to sleep... The message is that "Time Machine did not finish backing up because some files were unavailable. Backups will resume when your Mac is unlocked."

When the Mac Studio is not in Sleep Mode, all is fine... This has never been an issue before...

Is this a me-problem or a Beta-bug?

It's not you...I'm having the same issue. I even changed system setting to tell my drives not to sleep, which given that they are SSD seems to make the most sense...still no joy. Please let me know if you find any solutions.
 
Forum wouldn't let me edit the above, but I wanted to add that I am running 14.5 so this is definitely not a 15.x beta issues...also depressing because it means that 15.x doesn't fix it.
 
CCC has its share of issues, and I gave up on it. I have been happy with ™ for years, and it worked prior to Sequoia.

Just wondering...
What were those "issues"?
(inquiring minds want to know...)

I had a crash when using CCC, and the restore failed repeatedly. I had it set to exactly how CC was saying to set it, and I was even on the phone with their support, but they gave up with the words, "Sometimes we see that, sorry."

Also, the CCC client has an interaction problem with Snapshots taking a lot of space. I couldn't get CCC to limit the space it was taking, and the 2TB internal storage on my Mac Studio eventually filled up.

I still use CCC, but only to back up essential info on my internal storage and external drives to my NAS.
 
TM works fine for me, except when I leave my Studio running, and I come back after a few hours, and the backup failed. I kick it off again, and it works fine.

I am having no issues with TM or CCC. TM does the backup every hour weather the drives are asleep or active. CCC does the backup every day at the scheduled time. Current Setup: 2 4bay Thunderbolt 3 enclosures; both attached directly to my Max 2 Studio. One TM drive in each enclosure 4tb SSD; One CCC backup in each enclosure 1tb SSD.
I would check with manufacture of your backup drive or enclosure. In the past I have had problems with firmware on enclosures and firmware on the drives; both SSD and HD. One more thing; all TM, CCC, and internal ssd are encrypted; CCC encrypted using File vault; TM encrypted using Disk Utility
 
same issue: Sequoia 15.1.1 + M1Mac Studio, no hourly TM backups (Samsung T7 SSD via USB3) while Mac is sleeping.
Yesterday before updating (from Sonoma), there was no issue.

Same here, when connect over usb TM works, when over the air, TM failed. Day before update op .01 everything was fine.
 
Has this been fixed with the latest MacOS Sequoia beta? My new Mac mini M4 Pro has failed TimeMachine backups when the display is put to sleep.
 
I am still having the issue as well, but it is not consistent, and I think it is related to a background running application.
 
I updated to Sequoia over the weekend just past. I've started having this problem. It occurs when the computer is locked. I prevent my computer from sleeping for other reasons, so sleeping is not required to trigger the issue.

I use three disks connected to a CalDigit TS4.

One thing I haven't tried is to see if the problem happens with a brand new backup rather than one which existed before my upgrade to Sequoia.

Yet another new bug in macOS seems confirmed here. While not helpful to those suffering from this one, the lesson to be learned is to WAIT for .4 or .5 updates vs. jumping in early on what seems to be increasingly wide beta release macOS software. My upgrade strategy is exactly that (up from the traditional "wait for .2 or .3") and/or approximately WWDC... as each late stage version tends to work out most of its flaws for the approx. .5 to .<final> update.

Don't we all miss "just works" Apple?

Hmm, I noticed this week that trying to reload an old version of a pdf file from Time Machine (about <2hr old) the TM file is blank.
Now I wonder if TM is loading/saving anything at all?

nope sorry, everything nominal

EDIT - apologies for any irrelevance in the post below: my issue was due to installing 15.2 *direct* via a USB stick in safe mode to a Thunderbolt external volume; rather than via the original OSX installation on my M2 mini's internal SSD. This apparently caused tiers of grief & hassle relating to locked/encrypted folders created by Apple Intelligence processes (which doesn't work from an externally booted installation).

OK - had similar (non-identical) Time Machine hassle in Sequoia 15.2 involving "Biome" . . . . solution was:

1: under Settings/Privacy & Security/Full Disk Access . . . . enable Terminal
2: (there will be a Terminal restart), Then: in Terminal, type: "rm -rf ~/Library/Biome/"

. . . this sorted my - stressful - hassle; Hope it does the same for those of you, whose Time Machine errors include: "Biome"

With respect, I don't think deleting system created folders in ~/Library is a good idea. As a workaround, it is better to disable TM backups of the folder. Better still to diagnose and fix the problem.

The feckless leadership of Tim Cook ruined Apple by completely losing the focus on quality software. I now no longer upgrade software from Apple like I used so since the days of System 6. Tim Cook's Apple does not give one damn about quality.

It may help to peruse this thread Time Machine Error and peruse 1-Dec-2024 posting by iammike1. If it is a single file preventing backup, you could find the culprit with the command
log show --info --style compact --predicate '(subsystem == "com.apple.TimeMachine")' --last 24h
Click to expand...
and look for errors or output just before the string
failed: BACKUP_DELAYED
Click to expand...
and report the issue to Apple at their Apple Feedback assistant: https://feedbackassistant.apple.com/.
If enough of us complain, they may bring back the previous behavior.

In my case, it was that TimeMachine would not backup at night if I had the screen locked....
