Time Machine Backup not available in Yosemite

[mintakax]

I find it curious that no one with the new 5K iMac is complaining about TM/Yosemite issues. Does this mean that these issues are somehow related to software/hardware combination ?

Could very well be.
Unless people are not checking their TM backups, incidence of these problems does look spotty.

I suspect there are few 'in the wild', so if anything I'd anticipate only questions/problems about restores from backups created on other machines.

I guess there is a chance that the symptoms I see maybe due to the slightly aged Mini I'm using; I'd be astounded if they were down to the external drives as I see the same effects on three disks, all from different manufacturers and different capacities.

Could very well be.

I'm personally sure that even if they do them, almost no-one checks their backups, until its too late that is.

Looking at some of the other threads here and on the Apple site; some of these problems were being reported in July if not earlier

Human nature being what it is, I too expect inchoate howls of outrage popping up in this forum for months to come.

Me too, and like you I don't expect a fix any time soon

From what I remember, when the first multi-source disk version of TM was released it was about six months before it settled down; deadlocks with open files, didn't know what to do if the OS had put a disk to sleep,...

Another of my backup methods gone as well...

"Toast 12 is currently not compatible with MAC OS Yosemite. I will update you once a patch or update has been released. "

and this for a product Roxio released in August

There do, in fact, appear to be big problems with Time Machine in Yosemite. I am unable to navigate back in the Star Wars interface at all except if I start from the Macintosh HD and drill down to the file that I want from there. That works. That said, I hope Apple fixes these problems in 10.10.1.

I have the same problem in the Star Wars interface, and like you I can navigate back when starting from the Mac HD. Apple must fix these problems (hopefully in 10.10.1) for TM to be truly viable. I hope you have an additional (non-TM) backup as well. It is wise to do so even if TM works perfectly.

----------

Now it's flaky/crashy again.
My Console shows me the same "unpredictable behavior" warnings as you see.

Guess I'll turn Time Machine off and wait for at least a semi-official fix; remembering to be especially careful about manual backups until that comes out.

I would be concerned about turning it off unless you have some other external back up. You place yourself in grave danger if your Mac crashes or if you have to do a clean install if you do not have some type of external backup.

----------

I primarily use a different automated system to backup, paid for and has not had bug/failure that has impacted me in seven years; using TM mainly for any intra-day recovery

However, this afternoon every time TM runs it has thinned (deleted) precisely one backup completely ignoring the time difference (since when was 19:49 yesterday more than 24 hours before 16:10 today !!).

I've seen the same thinning and don't know why it's doing that. I haven't changed anything so this should not be happening. Another bug for Apple to fix in the next update, which I hope comes soon.

Of course I employ a secondary backup system. Doesn't everyone?
Even when working properly, Time Machine provides a Single point of failure style backup. That's dangerous.

I have contact Applecare support and I have spoken with a second level support engineer that has confirmed the problem with TM old backups and Yosemite. He told me that next update will probably remove this bug (but he doesn't seems too sure...) and at this moment he doesn't know the date of this update.

In my case new backups are ok and I can use finder to navigate old backups through Finder, so it's not probabily a big problem but first impression wasn't so good.

I can confirm issues with time machine which ironically only seems to be since release version. Such a shame, but like others i can manually access backups and the like.

Hopefully first update WILL fix this issue but I don't see any mention of it in the info for the beta update.

That's the only bug that i've been able to replicate. No idea whether reformatting backup drive and starting again would fix it but kinda seems silly to do that given the whole point of backing up.

Also having issues

Figured I'd throw in my $0.02 worth as the more posts the more likely Apple is to resolve it. Sadly, in my case I've reformatted and re-encrypted my ™ drive multiple times. The first backup always completes, but all others hang with something like "Backing up XX.XMb of XXX.XMB" and never progresses. Sometimes if I stop the backup and manually tell it to it will complete. Most times it will not. Checking logs shows:

Not starting scheduled Time Machine backup: Backup already running

Sadly, its not generating errors... so the phone-home's to Apple won't get there. Here's to hoping Yosemite XXX.1 (OS X 10.10.1) resolves this...

You do realise Apple's not affiliated with this site in the slightest, so even if posts mount up here it won't be brought to their attention that way. I'm just hoping an update will clear it. Backups are the one thing you DON'T want to go wrong.

Still not working for me, Keep being told Backup disk is unavailable.

Have rebooted the Mac / Time Capsule. My rMBP is unable to back up either. Seems to be a over the air thing, my Mac mini at work will backup to its USB connected disk.

All Macs un Yosemite

I was getting this with an TC/AE... and on closer inspection it was something to do with Airport Utility losing/forgetting the TC/AE.

To resolve, I switched back to my old router and bridged the TC/AE for backups... This seems to have resolved it for now and it has also resolved the (x) numbering of my machine in Sharing Prefs.

Just disabled Wireless on the TC, still nothing. This is really odd. Hopefully Apple fixes this in the 10.10.2. None of my Macs have backed up since November 29 bleh
