Time Machine not working with Yosemite

Yes now TM works as designed in 10.10.2.

10.10.2 mostly fixed my Time Machine issue as well other than being a bit slow making the initial snapshot connection. It takes an average of 70 seconds for the "waiting" message to disappear in a snapshot Finder window's title bar and the folder contents to appear. However, once the first snapshot window fully loads with contents visible, moving between any other folder within the same snapshot or other snapshots is instantaneous with content immediately available. This is a minor bug IMO and one I can easily live with but it does exist regardless and it appears to be unique to Yosemite as TM access is immediate from Mavericks partitions on the same machines. I can live with the lag regardless.

I have found that the speed of TM is partially dependant on the drive speed. A 7200 RPM TM drive will access faster than a 5400 RPM drive.

yep, my MBA 2014's drive is a tad faster than my mid 2011's iMac's SATA but the lag is still present with both. Interestingly both PCs immediately connect and show all data instantly with their Maverick's partition...clean installs, network throughput, etc all being equal. Regardless, the lag is not a deal breaker by any stretch. I'll gladly wait 70 seconds to recover a file ;-)

P.S. the few wifi signal drops I experienced on .0 and .1 are completely gone with .2

I thought it was fixed but paranoia has made me go into time machine regularly and check and I am finding that it is not stable for instance this morning no matter how long I wait i cannot access more than 34 days back .

I am running Late 2011 MBP with Airport Time Capsule

Further to my last post and after reading other forum posts I tried opening Macintosh HD and then enter time machine by doing this all dates and folders are immediately accessible

Luckily for myself, Time Machine is "finally" fully accessible, but I also check it a lot just to make sure. Now if only my WiFi worked properly. I was posting a little while ago, in the WiFi forum, because my WiFi has had problems, for over a year now, and inadvertently mentioned my Time Machine trouble in the same way. An upper level guy coldly responds, how "no one else is complaining." I posted a link to this forum. Yosemite works for some people, but not others. There may not be as many complaints for Yosemite as of yet, but give it time.

I used to have wi-fi problems but since started using the airport time capsule it has been faultless. What wireless router are you using?

Update: I installed OS 10.10.2 and now my iMac is backing up properly to Time Capsule. I haven't thoroughly tested it but based on the other posts, I can rest easy that its working. Thanks to the people at Apple who worked hard to to fix the problem, I appreciate it. Even if others may continue to be unhappy with the initial problem, the wait, the lack of public notification that a problem existed and the lack of acknowledgement of the same, I salute you for getting the job done. As long as I can do what I need to do on my computer, my allegiance will stay with Apple.

Hi, I downloaded Yosemite last week and since then it won't run a back up. I have read the many posts on here about being unable to restore from previous backups (all my previous backups have gone too) . These posts are interesting, but my first issue is that I can't do a back up right now - I don't need to restore anything at the moment. The error message says that only 16.1 GB is available on the 250 GB external hard drive, and 40 something GB is required. The only changes since the last backup are a few word/excel documents, but nothing of any great size. My hard drive is a few years old, is 250 GB just too small for Yosemite? I've never had a message that says there isn't enough space before, so is this just the size of Yosemite which has taken me over the size of the external drive?

The storage info says there is 209.74 GB of 'other' on the external HD, but only 59.96 GB on the internal HD - does this seem right??

I went into options and deleted 2 large movie files from the backup (although they had previous not been an issue) but I wondered if they were too large. The only other item in the pane was the external HD itself.

I'm not tech savvy enough to be able to look at any logs etc to work out if there's an issue there I'm afraid!

Would really appreciate any advice - thank you.

Sorry Raymy, I meant to reply to the original post - not to you specifically! I'll post it again

Yosemite seems to be working fine for me.
I believe I have restored from Time Machine before, but now when I enter Time Machine I see many back-ups but none of then show available to restore?

How can this be fixed?

I noticed that my user switched to Guest User ..changed back to my user and every thing went fine .
