Internal Time Machine HD Disappears

Hello all,
I have an early 2008 Mac Pro with the following:
4GB RAM (Soon to add additional 8GB)
120GB SSD (Mac OS X Boot Drive)
750GB HD (Data)
2TB Internal HD (Time Machone)
500GB Internal HD (Boot Camp WIndows 7 Drive)
My 2TB drive just disappers randomly. I check the SMART status and it shows its fine. The disk appears okay and it shows up in Windows. When I leave my computer up and running with the monitor off, I come back and I get a message saying that Time Machine drive has ejected. I'm currently running Mavericks 10.

From the menu bar, select
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.

Time Machine backup disappears when iMac sleeps

Tried finding this topic but could not find the specifics. I have an Intel iMac running 10.6.7 and I use a Mercury enclosure with a Seagate Barracuda 2TB SATA for Time Machine backup, connected with FireWire. Every time my Mac goes to sleep overnight, the next morning, the Time Machine icon disappears from the desktop. It's been disconnected, because when I run Check Time Machine, the log reads thusly:
<<Thu Apr 21 10:29:30 com.apple.backupd-auto Not starting scheduled Time Machine backup - time machine destination not resolvable.
Thu Apr 21 12:30:05 [0x0-0x2d22d2].backupd-helper Not starting Time Machine backup after wake - failed to resolve alias to backup volume
>>
Occasionally I'll get the error message on the Mac that a device has been "improperly disconnected" but most of the time when it sleeps the TM drive icon just goes away (even tho the backup drive is still on).
Any ideas? Can I fix this or have to live with it? Are there alternatives to TM that may work better?
Thanks for any help/suggestions.
Best,
Mike

I had the same problem as Bru-Hed, but with a Samsung G3 Station 1 TB with USB-connection. After waking up the MAC the message "improperly disconnected" appeared. Was happy with the solution you gave and changed the power save settings accordingly, the drive holds its power, but....... things did not change. Switching off the MAC and restarting gives no problems with the back-up drive, but after waking up I have to reinstall the back-up drive every time by disconnecting and connecting the USB-connector. After choosing the drive again in Time Machine, everything works properly until the next time the MAC goes asleep......
Any other solution to this problem ?

My brand new back up drive is connected but now time machine has disappeared after working perfectly for a week. - no icon, not appearing as an option to save to - have rebooted everything a few times.

It's not clear whether you were able to do any backups to this drive at all. If not, it's probably not formatted properly. See #5 in Time Machine - Frequently Asked Questions for instructions.
If you did get any successful backups, there may be a problem with the drive, or the backups may be corrupted. Try to repair the backups, per #A5 in Time Machine - Troubleshooting.

Time Machine HD disappeared!

I have two external hard drives connected to my computer: One is a 500 GB My Book (used for time machine backups), connected directly to my computer through firewire 400. The other drive is a 1TB My Book (used for storage of large audio and video files) that is connected through the 500 GB through a firewire 800. This configuration has always worked fine in the past, but then a couple of weeks ago, the time machine volume simply disappeared from my computer. I have tried unplugging, and re-plugging all of my connections, but it simply can't be found. The odd part is that the larger drive that is daisy-chained through the time machine volume is still available, so I know that my computer is at least recognizing the connection through the time machine drive.
My boss had a similar problem around the same time. She only has the one hard drive plugged in (500GB My Book connected through firewire 800), but one day it simply disappeared from her computer and can't be recognized anymore. And now that I'm the one that suggested we go out and spend the money to get every computer in the office an external HD for time machine, and they're starting not to work, I;m getting some serious pressure to figure out a solution.
I'm getting desperate! Any thoughts or suggestions would be MUCH appreciated!!

Well thanks for trying to help, but nothing has worked. I selected none and turned off time machine, but then when i tried to start it again, the hard drive was still not available. Also, I don't seem to have that preference in my library.
No, not in your home folder's library. TM is a system-wide application -- the file is at the top level of your internal HD. Select it (probably named +Macintosh HD),+ then look for Library/Preferences/com.apple.TimeMachine.plist
But if Disk Utility doesn't see it, that's not going to help.
I thought maybe i was just overlooking it, so i even tried entering the preference name in the search field and couldn't find anything.
It's a system file, so the only way to find it via a search is to use a Finder Search and include system files.
I tried checking in the disk utility as you suggested, but it was not on that list either. As I said before, I know my connections are solid, because the hard drive that I have daisy-chained through the TM hard drive is completely accessible. I'm starting to fear that my HD has gone kaput.
Sure sounds like it. Does it have an "off" switch/button? If so, turn it off for a few seconds, then back on. Can you connect it to another Mac? If it's still not recognized, it's probably dead. What make is it, and how old?
Note that your boss's problem may not be the same -- use the same procedure there, starting with whether there are any recent backups, etc.

Time machine backups disappear Yosemite

Since upgrading (that is a joke) from ML to Yosemite I am seeing backups on time machine disappear from my back up drive. Another oddity is that the icon does not spin around while backing up. Any help would be appreciated.

The Time Machine icon stopped spinning when Mavericks was released in the Fall of 2013. Instead, since that time, there is a bit more of a separation in the lower left area of the circle (near the arrowhead) when the backup is occurring. Further, the arrow turns into a double arrow.
Backups may well disappear as the disk housing the Time Machine backups becomes full.

Qnap time machine keeps disappearing

I'm new to Macs since January and we got a new Window 7 PC at the same time, along with a qnap, because it could do Time Machine backups.
I've had the same problem as many people since I got the kit - i.e. Time Machine insisting I need to make a new backup, which I've always done, though it was annoyingly frequent. Anyhow, that's not the real issue.
For the third time since January, the whole Time Machine set-up has just disappeared from my Macbook Air. Only this time I can't get it back. It can't see it in my Finder, but I can find it under servers, in Recent Items. Last week I was able to connect to it by this means, though not reinstate backups. Now, when I try to connect is says it is unavailable. We've not changed anything and as I am the sole user of Mac in our household, the Mac is getting the blame!
Sadly the demarcation lines extend to the QNAP, which is NOT mine, and unless I can find the cause of the problem and provide the fix, I'm not going to get any support. I've googled the issue extensively and passed on the results to the QNAP owner, but we've not been able to fix it and I've had no backup for over a month.
Aside from asking for a Time Capsule for Christmas, and doing my own thing, does anyone have any suggestions, or similar experience, or even know of a good resource for QNAP problems?

The device is either misconfigured or is unsuitable for use with Time Machine. I suggest you stop using it and back up to a locally attached external hard drive. If you don't want to do that, stop using Time Machine and use some other backup software. I don't have a specific recommendation.

Time Machine backups disappear

Hi - All my Time Machine backups (3 months worth) have disappeared from my LaCie Quadra Hard Drive after my last Time Machine backup. Either at the end or during the backup, I got an error message saying "Bitmap Mismatch". Any suggestions? Thanks, Bernie

Well yes in principal I'm sure you're right about the drive capacity but I don't believe its a space, or lack thereof problem. I can't say that there was any unusually large backup that occurred that might cause it to wipe off the older backups.
I have done verification on both source & target drives. No issues found. Same with Techtool.
Yes, I also run Superduper every day to an external drive so at least all is not lost when TM fails. All drives are permanently attached & the Mac runs 24/7.
I also run the TM Buddy widget, but it only records info so far back and the challenge is being aware that you have lost the backup when you don't check it every day. By the time I notice the problem the info that might help diagnose the problem is gone!
I understand but it's really impossible to say now what might have caused it without seeing log info. file system errors are one possible reason but you say all drives check out fine. anything else would be unverifiable speculation at this point. once thing i've noticed in the past that any kind of problems with superduper backups can cause this. so if you ever get any issue with superduper check what's happening with TM.

Time Machine disk disappeared

I have a Powerbook G4 and have an external drive for Time Machine. Suddenly the disk disappeared, so I turned off the external drive to eject the disk and reconnect/restart it. Now the disk will not appear. I cannot set up Time Machine because the disk does not appear. How can I get Time Machine up and running again?

Sounds like a drive issue rather than an iPhoto. Try the TM drive on another Mac to see if it is still working correctly. I've had problems with my TM drive on occasion. I have to turn it off and shut down my Mac. Then turn on the drive and boot the Mac.

Time Machine backup disappeared--devastating loss

Long story short, my system drive became corrupted and I wasn't able to repair it with Disk Utility or DiskWarrior. I knew my Time Machine backup was up to date on my Time Capsule, so I formatted (quick format) my drive and installed OS X again, thinking I could just reimport my info back from the Time Machine backup.
What happened is now the hard drive is not showing up in the sparsebundle file. The other 2 internal drives seem to be fine.
In retrospect, I know I screwed up process. But my question is, is there ANY way to make that backup available again? I know it all must still be there but somehow the link to it must have been broken and I can't access it.
I lost everything but the videos/photos of my 17 month old son is devastation. I really hope someone can save me here.
(I did use a recovery app (read only) on the system drive so I do have access to the raw data, but there are literally millions of files to sort through, many corrupted).

Disk Utility returned "The volume Time Machine Backups appears to be OK."
That was quick!
Would you know what the preference file would be that holds the information as to which drives are being backed up? I may be able to do a content search for it on my recovered raw data files. Id be curious--maybe I had accidentally added the disk on the exclude list somehow!? Maybe I wasnt 100% sure, because I havent had to access it for over a year at least.
/Library/Preferences/com.apple.TimeMachine.plist
(That's the top-level Library folder, not the one in your user home folder). It contains the current instructions; if you make a change, that will be reflected in subsequent backups, but earlier ones won't be changed.
But of course, if you don't have the backups, you can't tell what was in that file.
Lets say it was recently deleted somehow, is there any recourse to pulling anything off it?
Even if it was recently added to the exclusion list (all internals are backed-up by default), that wouldn't affect prior backups. Those would still be in the Backups.backupdb folder, until the entire backup (or all backups of a selected item, as below) was deleted. Since you have at least a year's worth of backups, it would still have been there.
If you really want to double-check, Time Machine puts a hidden, somewhat cryptic, log in each backup folder. Among other things, it shows which volumes were backed-up.
First, you have to change the Finder to show hidden items. See #A3 in Time Machine - Troubleshooting if you don't know how to do that.
Then via the Finder, locate the log file, shown in gray since we mere mortals are not authorized to read it, either:
Then you must give yourself read rights to the file. Right-click it and select Get Info. In the window that shows, open the Sharing & Permissions section at the bottom. Click the padlock and enter your Admin password, then click the plus sign and select your user account. That will give you read rights.
Open it with a text editor. Here's part of a sample, showing the "preflight" to back up two drives:
See if the "missing" drive shows up there. If not, it wasn't backed-up.
But then, even it it were physically delted, it wouldnt have been an accident, since it would have to be manually removed from each incremental folder and there are about 70 of them!
There is a "Delete all backups of ..." option in the TM browser that would do them all at once. It's almost impossible to do it by accident, though. See Time Machine - Frequently Asked Question #12.

Internal Time Machine "looking for backup disk" (not time capsule)

Hello,
I have the infamous "looking for backup disk" issue. My Time Machine drive is an internal drive, NOT a time capsule. It is mounted and visible, and the backups show up on it in the Finder. When I select to enter the Time Machine "starfield" UI, all my previous backups are browsable. But when it comes time to actually back up... it just says "looking for backup disk" forever. I've tried leaving it like that for something like 40 minutes, no joy. This is not a huge disk, there are about 700 GB of backups on it. The HDD activity light on my computer is NOT showing any activity when I am idling but it is "looking for backup disk," so I don't think it's scanning the drive or anything.
I have tried turning TM off and on, removing the drive and re-selecting it, unmounting it and remounting it, deleting the TM preference plist file from the library, rebooting, and all manner of combinations thereof. Nothing seems to work.
Anyone have any advice? This is on OS X 10.8.2 by the way. The TM backup worked fine through 10.8.1 and 10.8.2 with no problems until now. I don't recall doing anything specific to mess up TM or the disks in any way, although I may have turned TM during a reboot cycle prior to this happening (don't recall if this is actually the case, but in any case it shouldn't have caused such an error, no?).
Thanks in advance,
—Gabriel

[Just a note, TM only works on OS X Journaled drives (i.e. HFS+ drives). TM does not back up your FAT drive.]
Isaac:
If you unloaded the NTFS and FAT kexts, your TM backups might (might!) work again, but of course in that case you would not be able to see your FAT or NTFS drives in OS X, and if you removed the FAT kext then a lot of USB keys would be unreadable in OS X - not a good solution.
The kexts are specific to OS X, so removing them should not affect Windows... but may affect boot camp, I don't know how boot camp is programmed (which would be a problem). Luckily if your Windows drive became inaccessable from boot camp with removed kexts, it should be easy enough to simply boot back into OS X, restore the kexts, and then Windows should work again.
I would recommend not mixing partition types on drives with shared OSX/Win functions, it seems to "tempt fate" as it were with possible errors. I don't know what has precipitated this error in your case, if it was the MSE or disk error or something else, and unfortunately I don't have a real fix to offer beyond trying things with the kexts removed and seeing if they work.
NOTE THAT THIS IS AT YOUR OWN RISK, messing with kexts is not a very recommendable practice since these files enable core functionality in the OS. Make a backup before if you can, and consider your options carefully. In OS X, navigate to /System/Library/Extensions and you'll find a bunch kext files. The two you need are msdosfs.kext and ntfs.kext. Copy ntfs.kext into a backup folder (e.g., on your desktop). Delete the original ntfs.kext from the S/L/E folder. Reboot and see if you can still access windows. If so, reboot into OS X and see if Time Machine works again. If you're good on both those points, then consider going without ntfs.kext on a permanent basis – it is rare that you need to read an NTFS drive while in OS X. On the other hand, if this does not fix your problem, you may try restoring ntfs.kext, and backing up / deleting msdosfs.kext to see if THAT is the culprit. Unfortunately, if msdosfs.kext is causing the TM error, you're kind of out of luck, since going without FAT access will be pretty annoying any time you need to use a drive to swap files between Windows and Mac (using a USB key).
Ultimately I don't have a solution, as I have noted, so much as I've narrowed down where the error is occuring in some peoples' cases (like my own). Good luck!

6 TB internal Time Machine Backup Advice

apologies for the multiple posts today. i am trying to finalize my backup on a new system.
i have previously run an OS drive and another "data drive" in my mac pro while having the other two drives act as daily clones.
however i am having a hard time finding a reasonably priced external drive to back up my 4 TB data drive (it will give me a lot of years to add to it).
so i am considering buying a 6 TB WD "Red" drive and putting this in the machine and using this INTERNAL drive to act as a backup for the 4 TB data drive.
if i do this i can repurpose the 4TB drive that is currently acting as a clone for the OS drive.
if i do this i will have internal drives acting as time machine backups and i can buy a more reasonably priced 4 TB external drive to act as a daily clone for the OS drive.
is this a good or bad idea?
THANKS for any help as i try and finalize this.

hi kaz-k.
thanks a lot. it only now occurred to me that this might be more efficient.
can i please ask you if you happen to know whether i should buy one or the other of these? i guess i could post on a separate thread but there is a green and a red (NAS) WD hard drive. i have the 5,1 mac pro these days and generally buy the black caviar hard drives.
thanks

Time machine backup disappeared after upgrading OS from Lion to Mountain Lion.

I made a full backup of my 2011 Macbook Pro to my network drive through Time Machine in order to upgrade to Mountain Lion. However, after the upgrade, the backup could not be found. As it went through the install, I opted to recover the backup afterwards as I have read that you can do that after the upgrade. But the migration assistant could not find a backup.
So I looked in Finder at my external drive, and sure enough the backup is gone.
Some extra info:
So I don't know if this has affected anything important, I'm not that computer smart.
Prior to this I've been trying to get Windows 7 to work on bootcamp (still not working). I needed the OS X install disc, but I didn't have the install disc(I had OS Lion installed) and I bought the laptop from someone at work, so I couldn't get the Lion iso pulled from the recovery to a flash drive (it required the previous owners password to his apple account). Therefore I purchased the Mountain Lion Upgrade (Lion being no longer available. I didn't really want mountain lion). So when I started the Mountain Lion install, I had the "brilliant" idea to install it on the flash drive I had intended to use in the first place. Well, I didn't think it was gonna start the upgrade immediately after that. Anyways, after I realised my mistake I redid the install, process was the same, chose the main HD, went well. This was where I opted out of the recover-from-backup option. At this point I tried to restore my backup through the migration assistant. It said there was not enough room on the hard drive. I then noticed that all the memory used up prior upgrading was still in use, but under the old main user. I didn't do much with it, and thinking that my backup had my back, I did a full clean install. Another mistake. After the clean install, the migration assistant said there was no backup. I looked in finder, it was gone.
I didn't touch the hard drive thinking it is either hidden, or deleted but not written over yet and still could be recovered. I don't know how to explore these options, I can't find anything online about either. Or perhaps there are other options to consider?
Please advise.

It's early 2011.
I have been able to purchase the upgrade under my username at the upgrade price. I didn't know that Lion stays under the previous owner's Apple account. I mean I got that when I tried putting the Lion Iso on a bootable drive (for the purpose of bootcamp) it said I needed the username and password of the Lion purchaser, but I went to get my own license then, but it was Mountain Lion at the upgrade price. I didn't think it had anything to do with my backup.
So looking back, that seems like a warning Apple should have put out for people to be wary of. "Hey, don't buy a laptop from someone and then upgrade, you'll lose everything." That's a load of crap. I thought I had no worries as long as I had a backup. I've never needed a backup, then the one time I thought I was in good hands. Nope, I try to do something, and it takes everything from me. That was a lot of data worth of stuff. 550 Gigs! I was shocked and in complete disbelief the moment I realized what I had done.
I just don't want to give this up.

Time Machine drive disappears when i reboot

When i reboot my iMac, my USB-connected external Time Machine hard drive does not remount, and it is not visible in the Disk Utility program. The only way i can get it to remount is to power-cycle the external drive. Unplugging and re-plugging the USB connection does not work. This could be a hardware issue (particularly with the USB cable), but i just wanted to check to see if anyone else is experiencing this problem.
Thoughts? Suggestions?

Hello r_dizzle,
Thank you for the details of the issue you are experiencing with your external hard drive. I found an article with steps you can take when an external device is not behaving as expected
I recommend following the steps in the section titled "Top troubleshooting tips" in this article:

Time Machine Text Disappearing?

I was wondering if anyone else experienced this or knows how to fix it.
Sometimes, when I go to open Time Machine, the text on the two bottom buttons, "Cancel" and "Restore" isn't there.
Everything else is fine - the file name text, the dates on the side, and the window headings are fine. The buttons are still click-able (I know Cancel is on the left and Restore is on the right), but the buttons are blank.
The only way I know of to fix this is to reboot. After I reboot, the text is back and everything is back to normal for a while until it happens again - seemingly randomly. I don't know what causes it or how to stop it from happening.
Not a major issue as it still works fine, but still an annoyance. Anyone have any info?
Thanks.

Hi:
I have never seen anything like that happen, but I am no "expert."
It occurred to me that you might try running repair disk on your external drive. Candidly, I do not know whether that will help either, but it might be worth a try.
You might also look at these articles about Time Machine problems to see if any fit your circumstance:
