Resolved in DP6 - Beta 5 - Time Machine Stopped

[jsamuels]

I updated to B5 two days ago and Time Machine appears to be making updates but the Latest Backup Date has not changed in two days. When I enter Time Machine, I see what appears to be recent backups and I can restore files. When I Command-R on startup and use Disk Utility, the most recent restore backup is 2 days old.

I've filed a report with Apple but wonder if anyone else is having any issues with Time Machine.

Thanks.

Time machine isn't working on B5 for me either. It's runs very very slowly (like 1MB every couple of seconds best case) then after a while just stops completely. Backups stopped as soon as I installed B5.

There are lots of broken stuff in beta 5. Rootless too!

Rootless can be disabled the "official" way by booting into the Recovery partition (cmd-R unless you're dual booting in which case that'll probably take you to your Yosemite one and the option isn't there) and disabling SIP from one of the menu options.

it's only the terminal command that's gone from DB5.

So far, Time Machine seems to still be working for me.

How is rootless broken?

Same.

Still no joy here as the latest backup is still dated 27 July. Apple requested some additional data and had me run a script.

No backups since July 10th for me (first public beta). Submitted feedback and bugs, no response. Then I realized that even though my backup drive was "selected" it was also available as a selection, like there were two identical TimeMachine volumes.

So what I did was turn off backups, delete /Library/Preferences/com.apple.TimeMachine.plist
reboot
Now there was only one in the list, and asked me if I wanted to make it a backup drive. Then it told me it had to decrypt itfirst. 4TB drive decrypting is taking a LOOONG time. But I think it will work once it's done. For some reason it got confused and was probably trying to access the ghost drive during a backup. Just a guess. Good thing I have backup plans for my backup plans!

I'm using Time Capsule. Was working fine on PB1 and PB2 but it's completely broken in PB3. It's just sitting at "Preparing Backup" forever.

I tried to delete the /Library/Preferences/com.apple.TimeMachine.plist file and re-enable backups but it's still just sitting there.

EDIT: for hours now.

I had the same problem. The only way i found to make it work again was to wipe the backup disk and start the backup series from zero. I little bit dangerous but now everything is working fine.

Time Machine is again functioning under 15A244d. Whew . . .

Good to know! I realize it's a beta, but no backups is one bummer of a bug to deal with.

Fortunately it was a problem only with DP5, Time Machine worked for me on the initial 4 DP releases. I tend to take the warning to not install prerelease software on production machines pretty seriously. This time I gave in based on initial positive performance. Other then this hiccup, I'm pleased with DP El Capitan.

I hadn't realised the problem started with DP5. I got a warning that no backup had been done for several days and when I tried to manually initiate a TM backup it was going so slow (like 1KB/hour!) I had to stop it. I assumed it was a problem with the Time Capsule and eventually erased the disk and after that the backup seemed OK again, except it had to do a full 500GB initial backup which took 3-4 days.
