OS X :: Time Machine Not Doing Backups / Unable To Complete Backup
Aug 5, 2010
I have an Imac 24" and a Mybook external HDD. Ever since Leopard came out Ive been doing backups with time machine, then ...one day..I start time machine for my weekly backup..and this message comes up: "Unable to complete backup. An error occurred while copying files to the backup volume."
Now I notice that my external HDD was almost not spinning while time machine was trying to backup ... the status bar of time machine saying how much files need to be copied and the total amount of space needed was super slow .... and stoped at something like maybe 10 mb ...
I started time machine again ... same message.
I though maybe Mac OSX needed some permission repaires. So I did just that and after that did time machine again ... same problem ....
Then I said to myself ... maybe my External HDD has problems ... so I even formated the HDD, then stated Time machine again ... this time it was running smoothly just like before I had the problem ... but the problem came back after 6 gig being copied out of the 25 gig needed to complete the backup process.
Now ... I hope I dont need a clean install of my Mac OSX ... or maybe its my external HDD ... maybe my USB having problems?

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.

iMAC with OSX10.9.4 ; 8GB ram ; two partitions external disk formatted MAC jurnaled ; connected via Fire Wire or USB2 .
During Backup the sistem get stack and display into the "details window" Time machine was unable to complete the backup because unable to complete the backup folder.
This problem happens with USB and Fire Wire. The file backups.backupdb is excluded from virus scanning.
Also happens time to time that (without doing things) both the partitions of the external disk disappaire from the desk-top and a message "the disk must be ejected properly" is displayed.
This two problems are independent une to the other. I have change the backup disk but both the problems persist.

My Time Machine has been making the usual regular backups for a few months onto my Time Capsule. I just found that all the backups prior to about a week ago have vanished. It's not a disaster (I think) as I assume that the current backups reflect what's on my iMac (I haven't had to delete files from it yet).
Where did they go? Why did they go?
A possible connection: My TC is 500GB; my iMac 1TB. I recently put extra files for temporary use onto the iMac hard drive - Time Machine said (in effect) 'that's too much, try removing certain folders from the backup'. I excluded said folder and things seemed okay, but it would be at around the time I did that that my old backups have gone.

Just wondering if anyone has had a similar problem with the Time Machine. I bought a 500gb Time Capsule last July and it has been running perfectly until a few days agp. I noticed that all my backups were no where to be seen (when entering Time Machine on my MBP) and that it was doing a full backup.. The backup took the guts of 36 hours.
I've come home today to find that all backups are gone again and it is doing another full backup!!!Any ideas what is wrong here?

One Time Capsule at home
One Time Capsule in vacation home
MBP backs up everything on internal hard drive to Time Capsule at home, where we live during summer and spring. When moving to vacation home in fall and winter, MBP backs up everything to Time Capsule in vacation home.
During the 6 months at each residence, the backups work great to the Time Capsule at that particular house. However, after some time (maybe a week?), Time Machine displays an error in Notification Center: "Time Machine can't complete backup to Home Time Capsule" (when in vacation home) or "Time Machine can't complete backup to Vacation Time Capsule" (when at home).
It's obvious that this occurs because Time Machine was set to back up to 2 Time Capsules and expects both of them to be reachable. Is there a way to suppress these Time Machine errors for the time that we're away from one of the Time Capsules?

Can someone tell me how to configure Time Machine so it doesn't do a complete backup every time?I seem to get constant errors because my disk space fills up quickly. For some reason I don't think it did this when I first started using it. I use SuperDuper also, but have a drive connected to my iMac all the time for Time Machine.

Files can’t be copied onto the backup disk because it appears to be read-only. You may need to repair or reformat the disk using Disk Utility. If the disk can’t be repaired, you must use a different disk for backups. Open Time Machine preferences to select a different backup disk. Why is Time Machine insisting my drive is Read-only, when in fact it isn't? This is becoming a routine occurrence. What's troubling is the problem is easy enough to resolve by simply unmounting/mounting the Time Machine drive and selecting Back Up Now from the menu and it purrs like a kitten.
After performing the step outlined above, my latest Time Machine backup is tucked neatly away and everything is fine once more.

have a MacBook Pro 15" 10.7.4 which isn't working with TimeMachine any more When starting a backup, Time Machine tells me to backup 112kB (for example) .... an running and running, and after a short time "2kB from 112kB" ... and runnig and running and then "5kb from 112kB" and so on. The progress status is updating very slowly.
The weired thing is: the ".inProgress" file on the external hard drive (tried FireWire and USB connection) is growing to 85GB (the total used space on the hard drive) while Time machine status tells me it has saved some kB. And every backup is running in that way. Instead of backing up only the difference, all files where backuped - although the status is displaying a few 100kB - which should be the right size to backup.
- Repaired permissions > Same error
- Tried installing combo update > Same error
- Tried another external hard drive > Same error
- Tried cloning system to different hd > Same error
- excluded the Users home folder > Same error
- Interal hard drive speed > Over 70MB/s > OK
- External hard drive speed > Over 70 MB/s > OK
So had to be something with the System itself.

So I just successfully migrated all of my data and settings from my old iMac to my new 27 inch iMac using the Time machine backup on my Western Digital 1 TB external hard drive. Aside from the Time machine backup folder I also dragged a few other things over to the external hard drive because there was so much extra space on it. The drive is not partitioned.
So I'd like to start using Time machine with this new 27 inch iMac but the empty space that's left on the external hard drive is barely large enough to cover what I now have on the internal hard drive on my new 27 inch iMac. If I were to remove the Time machine backup from my old iMac there would be plenty of space again unless starting Time Machine on this new 27 inch iMac will just copy right over that backup file? Everything on this new iMac, the data and settings and so forth, is exactly the same. So is the user account. However the previous Mac was running Leopard while this new iMac is running Snow Leopard.
So if it doesn't copy over the old backup it will just create a new backup file? And if it does create a new backup file is there any point to keeping the old backup file since I no longer have the old iMac and wouldn't be able to access it again? Obviously if I didn't have to keep it I could erase it which would create plenty of extra space for me to start using Time machine again but with this new iMac.

I'm using Time Machine which makes periodic backups of my data to Time Capsule a couple times a day. If I had a problem with my computer would I be able to completely restore all of the data like the way it was?

i have a macbook with an internal drive of which about 230gb if full and used.
I have a 250gb external which i have been using to back up with time machine, done it several times over a few months.
Now there is like 70gb left on the external, and when i try to back up, it says failed, not enough space on external.
But i thought when there is not enough space, it simply deletes and backs over older time machine backups.

I am getting the following error from Time Machine when doing my first backup. The startup disk being backed up, and the TM disk are both the same size.
Macintosh HD: 465.44 (total); 393.99 (free); 71.45 (free)
Time Machine: 465.44 (total); 465.29 (free)
The Time Machine error is: Quote:
"This backup is too large for the backup volume. The backup requires 472.7 GB but only 465.3 GB are available." why would this be? Other disks are excluded from the backup, and Time Machine is telling me that it needs more space than it actually needs. What should I do?

Is it possible to have Time Machine overwrite an existing backup instead of making excessive new backups? If not, is there a way to control when Time Machine preforms its backup task so as to not make excessive backups?

I have time machine running as well as Parallels installed. Every time Time Machine backs up it does a minimum of 18.4GB. I 100% do not have that many changes each hour. BTW, running Snow Leopard. I have a screen shot of all the items I have excluded, but it still is doing it.

I have a time capsule at home and I am thinking about hooking up a hard drive to my network at work for time machine. Can my computer use time machine on both units? I'm sure incremental backups wont be saved on both. For example if I make two changes to a file at work and then go home. I wouldnt be able to go back to those two changes, but it would have the original from a older backup right?

I'm using 10.5.8 and Time Machine on a time capsule which should have enough space. I've unchecked the "ask before deleting" option in Time Machine but no dice. I suspect that the problem stems from when I copied my iTunes folder into my public folder so that I can share among user accounts. It's not a copy of the folder but rather I moved it. Still, I think that time machine is trying to hold onto two copies.

I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.
So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.
It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.
However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.
More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. (http://www.macosxhints.com/article.php?story=20080420211034137) Have not tried this yet as I thought it would be prudent to seek some help first.
Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):
Is this because time machine requires a network faster than 802.11g?
Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?
I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?

I have a 1tb external for time machine back up and have about 750 gb of stuff to back up. I was under the impression that when time machine backs up my stuff it will automatically delete the oldest backup to create room for the newer backup.
My problem is that i did a back up a couple weeks ago and then today i go to back up and it tells me back up failed only 718gb available for 740gb of stuff to back up
anyone have this problem? how can i fix it?

I am unable to "Enter Time Machine" to view previous backups! Time Machine continues to make backups, and I can access other preferences and options but clicking on the Time machine icon in the dock or in the applications folders does nothing!! How do I remedy this - I have repaired permissions but am wondering do I need to reinstall Time Machine? If so how do I reinstall Time machine?
