Time machine reminders missing in Yosemite?

With previous versions, a reminder popped up if you have not run Time Machine in 10 days. That seems to me missing once I upgraded to Yosemite. Is there a preference adjustment I missed?
Thanks.

I am using Yosemite 10.10.1 which I believe is the current version on my MaBook Pro

The 10 day alert for Time Machine has returned !!! I wonder if it was a part of the Yosemite 10.10.2 update.

How do I restore mail from Time Machine after a clean Yosemite install?

I've been having various performance issues with my iMac recently (wifi keeps dropping off, scan functionality on my multifunction printer stopped working, whole system periodically hangs) so decided to do a clean install of Yosemite. I also have a MacBook Air, also running Yosemite, and on which I have no issues with the wifi, printer or system performance.
Before doing the clean install, I made sure I had a current Time Machine backup. The process appears to have worked so far, but I have run into an issue restoring my mail. I think it best if I describe how I have restored my documents and then I can show at what point I run into a problem.
To restore documents, I opened Time Machine, used the keyboard shortcut command-shift-C to show the backups prior to the clean install, and then selected the documents I wanted to restore. This was simple and worked perfectly.
To restore my mail, I opened Mail, selected 'Enter Time Machine' from the shortcut menu at the top of the screen and then used the keyboard shortcut command-shift-C to show the backups prior to the clean install. This is where I got stuck as command-shift-C is a default shortcut in Mail that shows the colours dialog box. Hence I have been unable to view the correct backup. The backup I want is listed on the right hand side of the screen in Time Machine, but I can't work out how to select it.
I thought changing the shortcut in Mail might work, but I couldn't find a way to do that either since it is not listed in the Keyboard section of System Preferences.
Any ideas gratefully received.

Hey there,
It sounds like you're still having trouble exposing the proper library folder. You can use the following terminal command to do it globally (this will show all hidden files)
Open Terminal from your appliications folder and copy/paste this into it:
defaults write com.apple.finder AppleShowAllFiles TRUE (press return)
**After that last line you'll need to restart the finder so use:
killall Finder (press return)
Now if you enter Time Machine the correct Library should be visible. To re-hide your hidden files repeat the process above but replace TRUE with FALSE, then use the "killall Finder" again.
I agree with the commenters above, you should restore the Mail library to the desktop and then re-import it to Mail. This is how I was instructed to solve this problem by Mac help, who I chatted with online for quite a while before they figured it out.
Hope this helps

Time Machine backup missing bits of iPhoto library

I just noticed that the size of my iPhoto '09 library as seen in the Latest directory on the backup drive is a little smaller than the current size of my iPhoto library. The backup is up to date. I made sure by running Time Machine manually.
After some exploring I found whole directories within the iPhoto package structure that are just missing on the backup drive. For example, iPhoto Library / Modified / 2009 / Sep 26, 2009 is missing. I can't understand why. TM has run plenty of times since those photos were imported into iPhoto. I found other directories missing, too.
What's up with this? At this point I no longer trust Time Machine. If it's not backing up these directories what else is it not backing up?

Move/backup/move back/backup did not fix the problem. TM still didn't backup the missing directories.
I was finally able to convince TM to do the right thing by following the procedure described here:
http://www.nzmac.com/quick-tips/time-machine/how-do-i-reset-time-machine.html
This isn't a solution because I still don't know what caused TM to think that it backed up something that it didn't back up. But the article was suggested by a friend of mine in IT who also owns a few Macs. After following the procedure and running TM again I can see all of the previously missing files backed up on the ext drive. I also used BackupLoupe (http://www.soma-zone.com/BackupLoupe/) to browse the files that were actually copied by the last backup. I see that TM copied the directories that I knew were missing and two other directories that I did not know were missing.
At this point I think my TM backup is complete. But now I'm on the lookout for a better backup solution. Until I find it I'll need to periodically compare backup sizes to make sure that TM keeps doing its job.

La Cie Porsche Design External Hard Drive no longer working with Time Machine since update to Yosemite.

My La Cie Porsche Design External Hard Drive USB 3.0 is no longer working with Time Machine. Is Yosemite the cause? How do I fix?

Can you see the drive in Disk Utility? If so, try selecting it and using the Mount button in the top menu. You can also run repair disk and repair permissions.

Full System Recovery with Time Machine - Applications missing

Hi,
My Macbook recently met a nasty end by a glass of wine and ended up completely dead. Not to fear, I thought, it's all backed up on my Time Machine. So I got hold of a Mac Mini and started to attempt to restore my system using Time Machine. When I got the new mini, I ran my Leopard install disc, and followed the restore from Time Machine process. The first problem was that the version of OSX on my deceased macbook was newer than the fresh install I was putting on the mini, so the TM restore couldn't work. So, I continued the clean install, got OSX up and running and then ran the software update so that it was all up to speed (now running 10.5.8 - same as the macbook was).
Next onto Migration Assistant to restore from my Time Machine backups. All hunky dory, except that Migration Assistant told me that there were 0.0kb in the profiles. Once I'd peeled myself off the ceiling, I tried it anyway. Everything transferred across OK - settings, files, profiles, but no applications. Lots of money's worth of iLife, iWork, CS5, Office for Mac - missing. Files, but no way of opening them!
I had a root round in the TM backup and they were all there, but nothing at all transferred across in the restore.
What have I missed here? Should I drag and drop each application over from the TM folder to my new Applications folder? Surely the risk here is that I'll miss some system files in Application Support etc.
I really need some help here. Most of my applications don't have install discs as they were downloaded either from Apple/MS/Adobe etc.

Not a fan nor expert on TM, but anyway you ca pull the old drive out of the WineBook & use something like this...

Can I start new hard drive set up again?/time machine info missing!

Hi, hoping for some guidance as I think I've made a mistake with my new hard drive set up, and now my time machine hasn't transferred everything over as I've folders missing!
My hard drive packed up & a new 10.6 was installed on my Macbook Pro. Previously running on 10.5.8 which was backed up to time machine 3 week ago. I switched on and went through the 'set up assistant' but when asked 'Would you like to inherit (or reuse) the backup?' I think I chose 'Don't backup now' because I thought I could do my time machine later! I now know I have chosen the hard route!!
Then I tried the 'migrate assistant' - it took 1.5hrs - desktop has screen shots etc as before but I couldn't access thing like 'my pictures' in bridge etc. The dock has LR, PS, Bridge etc as before too. Then I deleted the new admin set up (so I had only my old admin.) I restarted - no change. I then tried 'migration assistant' again but transfered only 'Other files and folders' because when all ticked there wasn't enough room (-81gb)
Now I can go into LR catalog it only has 2 folders (instead of more than 20), and in Bridge I have files & folders, but on accessing them I get 'Items could not be found. It may of been moved or renamed.'
I've looked into erase & install - but I don't have the disc. Maybe I should go back to the shop who installed 10.6? Can I start again so I can transfer from time machine in the set up?
Any advise on how I can get my info back would be greatly appreciated!
Thanks, Heather

I have the same problem, but it is happening with various USB drives including an iphone. If I have any of these connected via a USB hub to the MacBook Pro, they mount and operate fine until I attempt to copy large files to them. Randomly, during large file transfer, the drive will suddenly disappear and I'll get the same error as if I had yanked out the USB cable without unmounting it.
This is happening with:
* A standard (Lacie) powered 500GB USB drive mounted normally.
* A standard (Lacie) powered 500GB USB drive being used as a Time Machine disk (it errors/unmounts during Time Machine backups).
* An iphone 8GB during itunes syncs, only when copying large files (like videos).
I have tried two USB hubs, one powered and one not, and both cause the same problems. If I connect any of these drives/iphone directly to the Mac then they work absolutely fine.
I first thought the (unpowered) USB hub was to blame, but when I started using the powered USB hub and saw the same problems I'm starting to wonder if OS X has a bug with regards to heavy I/O to USB devices connected through hubs...?
Davros: my tip would be to connect the drive directly to the computer (not via USB hub) and see if the problem goes away.

Time Machine Not Working After Yosemite Upgrade

I upgraded my MacBook Pro to OS X Yosemite last week. Upgrade was flawless. However, when I plugged in my 4TB external hard drive for Time Machine Backups, which had always worked before, the computer spent over 90 minutes "Preparing Backup" and never actually backed up. I rebooted to no avail. Help!

My family upgraded to Yosemite on our 3 Macs four days ago: on an iMac, a MacBook Pro, and a MacBook Air, all three Macs from early 2014.
In Mavericks there was never any trouble with the Time Machine. But now on all three Macs, the TM doesn’t function properly.
1) on entering TM, the Restore and the two Arrow buttons for selecting the date are dimmed out 90% of the time; nothing can be done, for example, clicking on the Finder folders or files and so on is impossible.
2) sometimes, however, only the Restore button is dimmed out, or vice versa, only the two Arrow buttons.
3) on two occasions, no buttons were dimmed out, but on the very first click, all the buttons were again dimmed out
4) on the iMac and the Mac Book Pro, thank God, the backups still seem to be working; however, on the MacBook Air, a „preparing backup“ message just keeps on running and running.
The TM is a major feature of OS X that Apple pushes hard in its ads. Hopefully this means we’ll soon have an update. As a normal Mac user, I would find it difficult to apply any more exotic workaround solutions that some Mac experts might offer. My patience and ability to troubleshoot doesn’t go much beyond David Pogue’s latest OS X manual.
Anyway, a last more point: the previous TM was a thing of beauty, and I really enjoyed being sort of shot into space with the stars, like Dante on his way to the Empyrean; but now, on entering the TM in Yosemite, it looks like the Finder has fallen into an ugly pool of mud.
Thanks for any help or feedback you can offer.

Time machine restore: missing thread record

Hello everyone,
I recently upgraded from Lion to Mountain Lion. I did a clean install. I have been backing up with Time Machine to my Lacie Cloudbox NAS. My NAS requires authentication.
I am unable to restore my files. I have tried it during installation and with Migration Assistant. I can see my .sparsebundle through Finder and mount it (and see an inprogress with loads of folders inside of it). I am unable to copy the files directly to my desktop because of an permission warning.
From Windows I can see loads of files inside the bands-folder. They are all equal in size. I found a clue that maybe the most recent ones are corrupt, so I moved two days worth of them out from sparsebundle.
Disk utility says the drive needs to be repaired. I tried this, and got loads of errors. I there are so many of these that I have shortened the list below a lot. Please help me, all my valuable files are inside the .sparsebundle (510 gigs). I don't care about automation, I just want them out.

The backup disk image is corrupt. You might be able to repair it by holding down the option key and selecting Verify Backups from the Time Machine menu. But that may also result in a total loss of all backup data. Backing up to a third-party NAS is unsupported by Apple and unsafe. You should back up to a locally-attached storage device.

Time Machine Backups gone since Yosemite install?

And on a second, possibly related, issue (as discussed in this thread: TimeMachine backups are not accessible after the clean install of Yosemite):
Just had a weird glitch with Dropbox recently whereby files and folders disappeared but I thought "It's ok. Everything is Time Machined. I'm fine!" only to discover that my backups on the Time Machine only extend to the last week... which is shocking, to say the least.
I know for a fact that a few days ago I saw that my 750GB external TM drive was down to about 8GB free and now there is suddenly 82GB free, plus a never before seen folder called "lost+found" next to the Backups.backupdb folder. What is it and where did it come from?
Just noticed now that my 750 GB drive holds 13.68 TB of data (that is seriously impressive), and that the lost+found folder is 22.66 GB big.
Fortunately, Dropbox has the "Restore Files and Folders" feature so hopefully nothing is lost but this Time Machine glitch is a horrible eye opener - all of a sudden I cannot rely on my backups extending back at least a few months, like I have entrusted it to do for years.
Since upgrading to Yosemite I have had a whole bunch of... seemingly trivial... glitches and bugs (dropbox syncing errors, re-establishing Apache and a local test-server issues plus a few other minor irritants plus the unexpected random reboot of the computer twice in the last 2 weeks) that have now all added up to leave me anxious about what new problem is going to manifest.
For example, in trying to view any Time Machine logs that might give a clue as to when or why the backups have disappeared I opened Console only to find that the console window doesn't appear. Anywhere. Even new ones.
I'm not a geek and have no idea how Console might help me but i was simply following the instructions in this link http://www.macworld.com/article/1131534/tmeye.html but Yosemite is not doing what I think it should.
This is what that app LogViewer Time Machine displays (seriously, my Console doesn't show a window - how do I fix that?) about the earliest backup, which is from Tuesday, Nov 18, 2014.

Any help or assistance or guidance would be deeply appreciated. Haven't had any major issues with this machine since I got it, till the Yosemite update.

Just back from an Xmas break in the wilderness and took a look at my Mac. Firstthing I see is that Time Machine has not backed up since 24th Dec. LogViewer for TimeMachine reports the following:

With variations of the same till today. My 750GB WD Elements external is still there visible on the desktop, displaying 66GB free with the "lost+found" folder and the Backups.backup folder, only this time neither is displaying any contents.
Seriously, does anyone have any idea what is going on with Time Machine? If I cannot rely on it for automatic backups I don't know what I am going to do. It has ALWAYS been there, working perfectly in the background and saving my *** numerous times.

Time Machine went missing. Where did it go?

After inadvertently deleting a bunch of photographs I tried to do a backup from Time Machine.
I clicked on the time machine icon on the desktop, (External Seagate HD), and the finder window opened.
I could see all the backups today, but never having used it before I didn't know what to do next. Anyway, in the left hand pane I saw an arrow to the right of the "Time Machine" legend. I clicked it and immediately the Time Machine icon disappeared from the desktop and from the list of available drives.
It was missing in the system profiler, couldn't be found by clicking the Time Machine icon in the dock. It was nowhere. I rebooted the Mac, still nothing. After tearing my hair out and swearing a lot, I moved the USB cable to another port, then turned the Seagate off and back on.
I've now got it back again. Success.
Ihave connected my iPhone to the original USB port and it appears to work ok.
My question(s)
What was the arrow and what did it do?
Why couldn't I find the Seagate even though it was still connected to the Mac?
Why did that port shut down and why does it now work?
Oh, please make any answers simple and easy to follow, try not to bog me down with technical phrases and acronyms.
Thanks in advance
Kevin

Welcome to the Apple Support Communities
You unmounted the external drive. The unmount is used when you want to disconnect the external drive safely, so it's normal that you don't see the external drive as connected.
To mount the external drive again, disconnect and connect the external drive again, or use Disk Utility to mount your Time Machine partition again. Anyway, there's nothing to worry because it's the normal behaviour

Time Machine Backup Missing?

I have been searching for lost photos for a couple of years, and have a new MBP and want to try to finally reaarange my digital life. I had stopped time machine from making backups because I was hoping I would not overwrite the backups that may have contained the missing photos, since time machine as it marches along eventually overwrites older backups to make room for newer ones.
So this issues has two main parts. First, I have all the missing "phtos" in its own iphoto library. Thus I can see about 900 or so thumbnails, but of course no photos to go with the thumbnails. I had hoped I could at least recover the thumbnails, but when I look in all my drives I don't see a folder associated with the thumbs - only partial thumbs that appear to be from face recognition attempts.
My next goal was to try to restore a backup from the time machine to the brand new MBP in the hopes that the photos may be in the backup. When I navigate to my time capsule, I can see saprsebundles there, but when I try to restore from time machine several I can't select which point in time to back up from. When I look at my time machine preferences on my current mchine (running 10.6.8), it shows latest backups failed, but not because it was turned off but because it says it doesn't recognize the username or password. I have updated the firmeware, and when I go into the time capsule through airport utility it shows everything operating fine, and I can access time capsule with no problem. When I click on time machine it says no backup can be found and asks if I want to setup time capsule. Now I'm stuck because I certainly don't want to accidentally erase any backups that may exist.
So how do I get to these time machine backups to see if indeed the lost photos are lurking anywhere? And can these thumbs somehow be found so I can at least save them? I know they won't be of much quality but at least I can see something when viewing them in iphoto.

Not sure why you say "at least three" unless the Time Capsule is set up to Secure shared disks with accounts (per the Disks window of Airport Utility). In that case, there may be multiple accounts on the TC; each one must log on with its name and password, and will see only what belongs to that particular account:
If you backed-up with one account for a while, then changed to another, each would have a sparse bundle for the same Mac.
Othewise, there should be one sparse bundle per Mac.
Should be only one sparsebundle, but I probably copied things in the past - this is almost 3 years that I'm still coming back and hoping to find these photos on a backup somehow. When I open Airport Utility I don't even see a menu bar like your image shows, and when I go to the menu itself all options including disk are greyed out.
Here is my finder window with the sparsebundles:
they all seem to have the same data in them.
They'll all have the same folder structure, but the contents should be the same as the Mac that made them.
But if the backups are made at different times you would think the files would be different. If I have photos taken every month, shouldn't the backups from say February have additional files than the backups from January?
The big question is are there some earlier backups lurking somewhere - I thought I had read that TM keeps earlier backups even though it may not display them.
If you don't see them via the Finder, either there's nothing else there, or there's some sort of corruption or damage.
So essentially it would seem that any backups from 2009 are gone if the earliest backup from the sparsebundle is dated 2010?
Since I see these backups through finder, would the display other tm backups display something different if I could get it to work?
Nothing extra, unless there's damage that can be fixed.
The sparsebundles seem to mount and open through finder, but nothing works through tm itself.
Have you tried the things in my previous post?
The things in the previous post seemed to apply if I couldn't mount a sparsebundle - I must be missing what to do when TM itself will not start from the dock or menu bar. I did reselect it as drive option and then turned off backups again.

Time Machine Restore fail from Yosemite

Ok, so this issue appears to be multi-faceted so please bear with me as I try to fully explain what's happening.
I have a mid-2009 Macbook Pro with OSX 10.6.8, and I decided to give Yosemite a try since it was free. Before upgrading, I did a Time Machine backup on an external 500GB WD drive in case I wanted to switch back to Snow Leopard.
I did the upgrade, but wasn't very pleased with the results. Seeing as how the computer was older I figured it would slow down a touch, but what broke the deal was when I tried to run After Effects and had plugins - that never gave me trouble before - crashing. I decided to restore from Time Machine and rebooted into Recovery Mode. However, by accident I selected the External Drive with the backups as my boot disk. I quickly rebooted AGAIN and selected the Recovery drive, but the TM drive wasn't showing up when I tried to access it for the backup.
I rebooted back to Yosemite and found that the drive was not mounting despite lighting up and making spinny sounds. Disk Utility could see it but was unable to repair, so I used DiskWarrior instead. Everything seemed to work out ok and the drive was reading on my desktop as a TM backup. I rebooted AGAIN to recovery mode, selected the appropriate backup, and let the computer do it's work overnight.
When I woke up in the morning and checked in on it, I got an error message saying that the restoration had FAILED at some point along the way. I tried to reboot normally, but the grey screen of death would appear after a few seconds and I'd have to shut down.
I went back to Recovery mode, tried to access the TM drive, but once again it was not showing up! So I reinstalled Yosemite and was able to login to my desktop. The TM drive was still showing up, and according to a reinstalled DiskWarrior the drive was fine. I rebooted in Recovery, selected the TM backup, and it only took about 20 minutes before the restoration failed! This time the computer appeared to be wiped clean, with no OS.
Fortunately I still had my Snow Leopard install DVD, so I managed to reinstall it from there. However, now I CANNOT login. My username shows up but the password I've used for FOUR YEARS is constantly rejected. I can't even login to the GUEST account!
If you've made it this far, PLEASE HELP!!!!

Boot off the DVD again and under the Utilities menu select Reset password. Boot normally and test.

Second Time Machine backup wiped after Yosemite install

Following on from my initial thread a few weeks ago (https://discussions.apple.com/activity?streamSource=connections&streamID=1989606) regarding the disappearance of my Time Machine backups from my iMac after installing Yosemite (7 people reporting a similar experience) and having noticed that the data seems to be 'hidden' on the backup drive, my partner upgraded her macbookpro and wow... lo and behold, the exact same damned 'glitch'.
Having not connected the external to the laptop for a few weeks after upgrading (yeah, yeah, I know) the reminder said something like "Time Machine has not completed a backup since 5th January" so we attached the external only to be given the error that the external didn't have enough room to backup the data and that the last successful backup was sometime in September 2014.

This is disappointing. Like seriously (insert swearword here) disappointing. No one has any idea what the glitch might be? Two different machines experience the exact same issue with Time Machine after upgrading is more than a coincidence in all my years of Apple fanboy-ism.
I am annoyed. Just letting folks know that

Not exactly the same error message, but start with C4 in the 1st linked article.

"Time machine not configured" after yosemite clean install

I'm on a MBP early 2011, 16gb Ram, Seagate 500gb used to back up with Time Machine. I was doing manual backups once a month. Having wifi problems like everyone else and general slowdowns on the machine even before the regular install of Yosemite (on top of Mountain Lion, on top of Snow Leopard) I decided to do a clean install. Start fresh. Followed all the directions. But,little did I know that by changing my user name (not deliberately) on my brand new OS, I don't have access to TM. At least that's what I think is up with this "TM not configured"
How should I proceed?
Can I configure the drive now with my new username and still have access to my files? I wanted to bring over some of them, not all of them. If it's possible to do this, and I do, will I have all kinds of permissions or other problems? Will I lose my old backups if I configure it?
Or should I just start over with another kind of clean install? It's only been a couple of days.If I restored from the backup or whatever options there are, am I actually reinstalling the problems I was trying to eliminate? The upgrade to 16gb ram was part of my initial troubleshooting.
Other options?
Thanks!

My family upgraded to Yosemite on our 3 Macs four days ago: on an iMac, a MacBook Pro, and a MacBook Air, all three Macs from early 2014.
In Mavericks there was never any trouble with the Time Machine. But now on all three Macs, the TM doesn’t function properly.
1) on entering TM, the Restore and the two Arrow buttons for selecting the date are dimmed out 90% of the time; nothing can be done, for example, clicking on the Finder folders or files and so on is impossible.
2) sometimes, however, only the Restore button is dimmed out, or vice versa, only the two Arrow buttons.
3) on two occasions, no buttons were dimmed out, but on the very first click, all the buttons were again dimmed out
4) on the iMac and the Mac Book Pro, thank God, the backups still seem to be working; however, on the MacBook Air, a „preparing backup“ message just keeps on running and running.
The TM is a major feature of OS X that Apple pushes hard in its ads. Hopefully this means we’ll soon have an update. As a normal Mac user, I would find it difficult to apply any more exotic workaround solutions that some Mac experts might offer. My patience and ability to troubleshoot doesn’t go much beyond David Pogue’s latest OS X manual.
Anyway, a last more point: the previous TM was a thing of beauty, and I really enjoyed being sort of shot into space with the stars, like Dante on his way to the Empyrean; but now, on entering the TM in Yosemite, it looks like the Finder has fallen into an ugly pool of mud.
Thanks for any help or feedback you can offer.

IPhoto library moved to Time Machine now missing

So I needed to beckup my HD and re-install Mac OSX, so I deleted my Time Machine file, and used the HD on it as a backup for files...everything.
Now I re-installed MAC OSX and my iPhoto library is nowhere to be found!!! Where did it go? I am really freaking out here, panicked, I NEED THAT LIBRARY!!!

Apparently it (the iPhoto library file) was hiding. It was ducked inside another Photos folder, and to further confuse matters, the newer, more recent file was actually smaller in size than the older iPhoto file (from iLife '06 I think).

Time machine reminders missing in Yosemite?
