Hardware :: Time Machine Not Working - How To Repair It
May 14, 2009
I am trying to set up my external HD with my Airport extreme and make it as my time machine so it will back up without me having to connect the HD every time. I tried this and the HD does not appear so i can select it and choose it for the Time machine Drive of choice. What do i do. I have seen others can do this but i do not know why i am unable.
I decided to restore to a Time Machine backup I had done a few days earlier, hoping that I would just "start" fresh. Without realizing it, I had inserted the Leopard install dvd that came with my computer, and restored to my 10.6.6 backup. I got the "You must restart your computer" error, which I found out was a result of using the Leopard disk. So, I redid the restore using a Snow Leopard installer on USB.
After this, everything appeared to be working fairly well. However, today, I've started to get system crashes quite frequently, and at times I haven't been able to properly shut down or restart. I noticed that Spotlight was indexing, and would hang at "3 hours remaining" or "estimating time left." Right now, I have created a second admin account, and I have disabled indexing. It seems to be working, at least temporarily, because I'm using it right now.
I have a Time Machine a a multiple partition. The TM disk didn't properly disconnect and now have disk error. I'm repairing disk through Disk utility. It's taking forever to fix. The drive is 400GB.I can stop repair but it's been repairing for an hour.
I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of action
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?
Info: iPhone 4S, Mac OS X (10.7.4), MBP, 2.4 GHz Intel Core i7
Yesterday I noticed that my computer had been trying to complete a backup for quite awhile... Well it turns out that it was only a 382KB backup and it was taking hours. I tried clicking "Stop backing up" and nothing happened. The drive was in a repetitious clicking rhythm, and when I tried to eject it, Finder said it was in use. I put my 10.5.2 install disk in and ran Disk Utility. I have two partitions on that drive, Beta and Charlie. Beta verified and repaired without a glitch, but my time machine partition, Charlie, said "Invalid node structure, volume check failed." Also, disk utility was unable to calculate how much space remained on that partition.
I am pulling my hair since friday trying to get my MBP's time machine work with a 1TB drive connected to a early 2009 AEBS. First I spent half a day doing the first backup by connecting the hard drive directly to Mac using USB and later when I connected that drive to AEBS, time machine would not recognize the drive as the same one and I had to spend a good part of yesterday backing up my complete drive again.... and just when I thought I can rest easy knowing that my eternal dream of getting time machine work wirelessly, I saw time machine complain that there is not enough free space left to backup my paltry 103 GB worth of data on just second day.
Turns out, the Time machine backup volume (volume created by time machine on the AEBS disk) shows that the used space is 1TB.... but the size of the sparsebundle is only 103GB and my airport drive mount itself shows plenty of free space (800GB).... I have tried to search for similar problem, but I couldn't find much help... can anyone help me out here....
Btw, when I tried to repair the volume in disk utility, it says something about incorrect allocation blocks and then says it cannot repair and I need to backup and reformat the drive or something of that sort....
I can't seem to get a working Time Machine backup going on my Mac Pro, late 2009 model. It's been problem after problem with everything I've tried. Very frustrating as I definitely need a reliable backup for an extensive payload of work files.
First I tried Western Digital MyBooks that I carried over from a PC. Formatted, set up Time Machine, worked great for about a month. Then Time Machine started to fail and stop backing up. Numerous formats later and the same problem persisted. I swapped MyBooks for another identical 1TB external and had roughly the same problem -- worked fine at first then Time Machine failures after a few weeks of use.
Next up, I tried a Seagate external drive 2TB. Virtually same problems.
Finally, I tried connecting Time Machine with my 2TB Airport Extreme. Not even one backup successfully completed.
It's been a couple months and I have gone for way too long without a reliable backup. I'm looking for alternate hardware and software suggestions, please.
I've looked at Drobos but I'm seeing a ton of complaints and failures cited. What are some other good options?
So I use an external USB harddrive with my airport to backup my computer. The harddrive is 250gb and the computer is 250gb (with about 40gb free space) - previously this worked for backing up just fine...then one day it stopped and started telling me it required "251.46gb" but the drive only has "249.05"...why if I'm at only about 210gb of actual space being used?
So I reformatted the drive and tried again - same error...anyway to make this work again...seems so odd that it was always fine and then just quit one day.
i have got an Apple minimac 80gb 10.5.7 with leopard and i bought a small drive of i think it is 116gb and time machine seemed to work ok,but i kept getting msg saying full,i did an erase on small drive and in finder i can see a drive called untitled,but if i click on time machine there are no backup dates?
Time Machine has always been working correctly but I no longer can make it work. I noticed no backup was available, only "Now" is in the time axis. So, I erased the entire disk and tried to set it up again, but still it doesn't work. 30GBs has been stored, but nothing is in the time axis except "Now". Any idea why it is not backing up?
Time Machine can not find a file that I deleted just a few days ago, which is very annoying, because I can find the file just fine when I open my external hard drive (my Time Machine backup drive) with the Finder and navigate to the exact date and location where the file was located when I deleted it.
Why is Time machine not working like it is supposed to?
I'm in the midst of moving from a 2011 imac to a 2014 - I have/had 3 TM backups 1) before the 2011 crashed and was repaired - 2) from the interim 2014 imac that I restored and updated for the new computer and 3) a "carbon copy clone" of my current drive because the apple tech made me wipe the drive and start over and it failed.
My computer will be here next week and I wanted to prepare. However since the restore of the repaired 2011 NO TIME MACHINE will back up on ALL 3 drives the same error happened. It would start fine and say it needed 17-22 hours to "create new" or "inherit" and would start fine and then freeze somewhere around 15-20GB????? I left it more than 6-7 hours and the freeze remained.
Need a TM expert...... this HAS to be a Mavericks OSX issue and I do not want to wipe another drive.
On 10.5 I used to have time machine backing up to a remote smb share using the time machine hacks to create a sparsebundle image on the smb share. No longer working with 10.6 - always get an error. Why apple couldn't make time machine get along with smb shares natively out of the box is simply beyond me.
I have a Time Machine 1.2 which worked perfectly on my old iMac OSX. A few months ago I purchased a new iMac which came with Snow Leopard, and it worked well. But when Apple came to upgrade me to Lion, the Time Machine no longer works. Is it not compatible with Lion??
At one stage I was told there was no room on the disk. I then tried to delete most of the previous backups, leaving only a handful of backups - but still no luck. I think I might have messed up things by then trying to edit the "do not back up" list. I tried to exclude some programmes applications , and now I am told there are no disks available to be backed up.
It is not very clear on the "options" screen, what one should do. What does the + and - indicate, and is it necessary to remove any files at all if I want a simple regular backup procedure on my home computer.
Lastly - if I wanted to uninstall and reinstall the Time Machine - is there a procedure?? I can't find one.
I have a mid-2012 MacBook Pro running Yosemite 10.10.1 that has started something. Here's what it is doing:
When I connect my external HDD for Time Machine to my MacBook Pro the internet stops working. By not working I mean, it is stays connected to the WIFI router with a full signal, but the internet, for lack of better words, ceases to function. I can't browse online, any app - like Mail - that uses the internet loses connection, and even background apps running on the top bar loses connectivity. If I run a Time Machine backup, eject the Time Machine external HDD, and pull the USB cable out of the MacBook it instantly goes back online and continues as normal.
I've checked settings, excluded Dropbox and OneDrive from being backed up in case they were conflicting in some way, and have searched for any answer anywhere I could think of.
The external HDD I use for Time Machine is 750GB and is the same HDD that the MacBook Pro came with originally (I swapped HDD to a hybrid drive internally and put the original HDD into an external HDD enclosure which has been solid for me for over 2 years now).
So I finally got around to getting a 1tb drive to hook up to my airport extreme to do TM backups. I have ~420gb to backup on my mbp's hard drive. To avoid an absurdly long backup, I did the initial backup via usb (took the better part of the day).
Just now I was excited because it finished - I hooked the drive up to the extreme, mounted the drive so that it would show up as an option in the TM pref pane for a backup disk, and thought I was good to go. However, when I tried to get TM to do a backup so I could see it work (by selecting Back Up Now from the menubar), it took a ridiculously long time "preparing" and I saw that it was trying to create a whole new TM backup on the drive based on my computer's network name. It even had the audacity to think that the previous backup file was ~2gb, which freaked me out because I thought it had deleted it. But sure enough when I canceled the new backup and hooked it up to my mbp again, the backup was the correct size.
I did a restore from a Time Machine backup. Now my iTunes Artwork screen saver isn't working. I'd try to do a reinstall from the Time Machine again to see if it still is a problematic, but I was an idiot and deleted it and backing up fresh. I've repaired permissions. I've gotten album artwork. My music folder reads like this. User/Music/iTunes. Inside are two folders. One "Album Artwork" the other "iTunes Media." Inside the "Album Artwork" folder is "Cache" and "Download."
I have a mid-2008 (June) MBP 15". Just upgraded to SL last night. I am having a serious issue with time machine. I've been using it with the same external HD since I bought my mac last year. No issues up until I installed SL last night. This morning (my first backup since upgrading), time machine started backing up (~ 9Gb) but just stops at around 300Mb. The clock keeps spinning, but there is no change in the amount backed up.
I'm reading that other folks are having this issue as well. Has anyone figured something out?I've run disk repair (nothing found), restarted my mac & external HD (several times each), and cancelled and restarted the time machine backup (several times). Each time it freezes at a different amount (i.e. 34Mb, 284.2Mb, etc...).
I've searched the web and the forums but I do not find anything that matches my problem, here it is. I'm using 1 Time machine drive (WD My Passport Studio 500 GB FW 800 for Mac) for my two machines, MacBook Pro (June 09, upgraded from Leopard with Snow Leopard Up to date disc) and my MacBook white (Late 2007, upgraded from Leopard with Snow Leopard retail disc). On my MacBook white, when I plug in the TM drive via USB, and when I click on the TM icon in the menubar, it says "Calculating changes (or similar)... (1, 2, 3, and so on %) until 100 % and the backup works just fine. But when I plug my TM drive onto my MacBook Pro (via FW), it says "Calculating changes... 1%" and it remains stuck on those 1%, but then after a while starts the backup properly.
I recently had my HDD replaced after a failure, and reinstalled 10.6.8 using Carbon Copy Cloner. The new drive came from Apple, and had 10.5.8 pre-installed (the OS that my late 2008 MBP came with), but CCC did what seemed to me to be an excellent job restoring. The clone was right at about two weeks prior to the old HDD failure, so once I cloned over, I only had to sync up with Dropbox, and manually move a handful of files (really from just a couple of folders for work) for things to be just as they were leading up to the failure. Here's what's happened (roughly) over the past week with TM:
1. Slow backups. Slow as in 1-2 KB/minute. This all starts with TM "calculating changes" which means about 20 minutes of crawling through and re-indexing(?) directories to look for changes. This happens each time.
2. Backups come in successive pairs. Time Machine Buddy shows this. One backup ends, having copied ~277,000 files (not a typo), then a second one begins immediately after, copies ~255,000 files (also not a typo), then either thins and/or deletes expired files.
3. #2 happens over the course of 2 1/2 hours, reliably.
4. After #2, the next backup comes about 2 hours later, starting all over again. Mere KB take the full 2 1/2 hours.
5. After each of the last backups, I have MORE space reported as available on the external drive. It seems to randomly delete backups from roughly 1 month ago.
Here's what I have tried:
1. Delete the TM prefs file in my user folder (not /)
2. Repaired the disk - things were very screwed up, with links needing repair all over the place. Thought this would solve things, but it didn't.
3. Hid the external from Spotlight's indexing
4. Deleted backups (via the TM interface -> "delete backups" option, NOT manually) after disk repair, in the event/hopes that initial backups following the new HDD replacement were bad.
5. Repaired permissions, etc.
6. Console doesn't throw what appear to be any errors. Just shows the successive backups mentioned above, the hundreds of thousands of files copied, and that TM deleted something each time.
