Time machine backup fails--not enough room.

I have a 2 TB drive in a Mac Pro running Yosemite (10.2) that I have been using for Time Machine backups. I have a 1 TB drive as my main hard drive that is about 2/3 full and another drive with less than 200 GB used. Unit recently, Time Machine has been working as it should. However, in the last week, I have been getting an error message saying there is not enough room (321 GB available). As I understand the process, older backups should be deleted when there is no longer enough room. Additionally, it should only be updating the backup and there should be enough room for that. Why can I not get a backup?

Time machine back up- not enough space so can't back up?

hi my computer entire hard drive is 2TB and only 1Tb used. and my external hard drive(time machine back-up) is 2TB. and right now Time machine back up failed. and keep saying that hard drive don;t have enough space....
i erase all from external hard drive ,, back up NEW. and still saying that not enough space on back up drive, weird thing is and i have 2.8 TB to back up.. but my entire hard drive is only 2TB .. what is that? and i only used 1.1 TB ish..
somebody help me? how can i use time machine back up with this issue?

What's shown for +Estimated size of full backup+ under the exclusions box in TM Preferences > Options?
If that's over the 1.1 TB used, there are a couple of possibilities:
Another internal or external drive, formatted for a Mac, is connected but not excluded, so Time Machine is trying to back it up, too. Exclude it, per #10 in Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum).
Something on your internal HD is corrupted, making Time Machine think it's much larger than it really is. Verify your internal HD, per #A5 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).

Time Machine Back Up Not Enough Space

I just tried to back up my Mac Book Air and I use OS X 10.7.3.
I got a message which said that there was not enough space on my external hard drive. The message said that I needed 50 GB and the external drive only has 43 of space... Note, when I check out the hard drive, it says: ""Available 43.63 of 249.93".
The sole purpose of my hard drive is for back up purposes. So, there isn't anything other data or information on the drive...
So, what do I do?

To be clear--is this a drive you have been using with the MacBook Air previously with Time Machine? Or is this the first time you've tried to use Time Machine with this drive on this computer?
If it's not the first time, I suspect you're just getting Time Machine's warning which everyone eventually will get (unless you've turned it off or really don't change many files) that it is going to need to delete something from the drive outside of its normal scheduled elimination of backups (normally it lengthens out the period between saved backups as the backup ages, figuring you don't need every hour's snapshot for the last three years). By its nature Time Machine's needs tend to grow over time and it will eventually consume all available space on a drive that it is given access to.

I recently took my imac in for a recall on the hard drive, they replaced my hard drive, i used time machine to restore all my files. Now when I turn time machine on it says back up failed not enough space, it is not overwriting old back ups.

Time Machine backup fails because "volume could not be found".

I just had my logic board replaced in my Macbook Pro and went to do a backup (yeah, I didn't do this right before it crashed) and now Time Machine backup fails with the message "volume could not be found" Under Time Machine/Choose Disk, it appears that the drive is the one selected. The computer "sees" the drive and I can read files on it. The only other thing that has happened in the meantime is that a friend helped pull a file off the hard drive that I needed for a project. No apparent issues there. Any suggestions?

You might try going to /Library/Preferences, then drag the file com.apple.TimeMachine.plist to the Desktop. Reboot your Mac, then try declaring the backup disk for Time Machine. It might help if you mount the backup disk first.
Are you using Time Machine to write its backups to the disk of a Time Capsule? If not, since this discussion section is for Apple's Time Capsule AirPort base station, a discussion involving Time Machine should be held on the discussion section for whatever version of OSX that you're using.

Time machine backup fails; error creating folder. Western Digital drive requires password which is perhaps/likely the issue. I can't eliminate the password/encryption.

Time Machine backup fails on new WD external drive (My Passport Studio); error creating folder (after several hours of Time Machine apparently working).
Background: I purchased a Western Digital drive from an Apple Store to use for Time Machine backup. I followed the Western Digital instructions that came with the drive for Mac. I didn't get the Time Machine prompt which the instructions indicated I would receive--namely to select whether I want to encrypt my Time Macine backups. (I already have a Time Machine backup I use at another location, which is perhaps why I didn't receive a prompt.)
I decided to install the Western Digital utilities and security software that comes on the disk--with a view to potentially encrypting the disk (since I still wanted to have an encrypted backup since I was mobile). I forgot that (from experience 2-years previous) that I shouldn't install Western Digital software because it just makes life really complicated.
I tried several times to do a Time Machine backup with failures each time (error creating the backup folder). I tried to get help from WD but I don't think the technicians were following what my issue was. Potentially I was not helpful in explaining it. I deleted the WD applications from my system after the first contact with WD. However the problem persisted--I still had an encrypted hard drive. After three phone sessions with three different WD techs I still could not get a solution. (By the second call I was not at all interested in having an encrypted drive--I just wanted to format and restore the drive to an unencrypted state so that I could have SOME kind of Time Machine backup.)
I still don't have a solution--either to get Time Machine working with the WD encryption/password on the drive, or to remove the encryption so I can backup. Right now my options are to return the drive to the Apple Store -- or get a return authorization from WD. Seems crazy since the drive is fine and I have the working password.

Never install "helpful software" provided by WD and Seagate (or any HD mfg.)
All such stuff is fluff and nonsense that interferes with normal HD operation.
Always when you buy a new HD, format it for Mac and then use it to TM backup or clone a HD, or archive data.
Less is more on HD new out of box. A "blank brick", no fluff and cotton candy software

Time Machine backups do not migrate from iMac to MacBook Pro

I just moved from a iMac G5 to a MacBook Pro. I love Apple's migration tool, but it seems that Time Machine backups do not migrate.
I checked with support, and did a basic amount of searching, and it seems that I need to erase and reformat the backup drive, losing all of my backups.
Can this be true? That's a pretty screwy backup solution.
Is it possible to rename the backup folder from "iMac G5" to "MacBook Pro"?
Is it possible to add a MacBook Pro backup folder to the one already there?
Any help is appreciated.

I'm not quite sure what you mean. It sounds like you successfully migrated, and got everything set up properly on the new Mac.
Now you want TM to just continue backing-up the new Mac to the old Mac's backups?
If so, then no, that's not going to work. TM keeps the backups for each Mac completely separate. This is usually an advantage, so you can back up two or Macs to the same drive without any conflicts.
Plus, the version of OS on your new Intel laptop is very different from the one from your old PPC desktop; a whole different set of drivers, and of course code for Intel vs. PPC.
So TM on the new Mac cannot treat the old backups as if they were from the new Mac. It must start a whole new "sequence" of backups for the new Mac. If there's room on the disk, you can leave the old backups there until you're sure you don't need them, but that presents another problem: when you want to delete them, you can do it only one at a time, via TM, using the procedure in item #12 of the Frequently Asked Questions *User Tip* at the top of this forum. That's rather tedious and time-consuming, so most folks just erase the TM drive and let it start fresh.
If I've misunderstood, please clarify the situation.

Help: startup-config file open failed (Not enough space)

Who can help me ? I've an uc500 and he stil running. Now i want to change something and want to save the configuration first. But the following message appears : startup-config file open failed (Not enough space)
this is the output from a dir flash:

OK.
Try this:
conf t
service compress-config
And see if that helps.
If not, see if you can tftp the running config off the router and TFTP it back to startup-config:
copy run tftp
copy tftp start
Then you can try a reload and see if it is cured.
I googled and found a few cases where alot of ACLs or NAT rules could cause MALOC errors (you would see those in your logs) when implemented and could manifest itself in this condition, which could be cured after the next reload, which is why I suggested that.
Of course, dont be remote when you do this and only do it during a maintenance window.

My Time machine backup fails with an error message

Time machine used to work just fine when I first upgraded to Leopard but now every time it tries to backup I get an Error message "Unable to complete backup. An error occurred while copying files to the backup volume." This occurs while Time Machine is "Preparing". Next hour it starts all over again and does the same thing. I have reformatted the backup drive but still get the error. I'm backing up to a 300g Firewire drive and have used about 207G for the backups.backupdb folder.
An ideas how to resolve this issue?

Here is a list of some TM articles that may help. You can look for more by searching Mac Help from the Finder's Help menu or searching the Knowledge Base from Apple's Support Page.

Time Machine backup fails in extended network

Dear all,
I've recently setup an extended network using 2 additional AirPort Express units connected to the main Airport Extreme modem (all working well). I'm using the Extreme for Time Machine Backups, which used to work just fine as well.
However, when connected to the Expresses, the Time Machine Backups fail with the message that the backup file is already in use. I'm guessing the Express modem tries to connect to the backup file, while the Extreme is keeping the file stand-by or something.
Does anybody know a fix to this problem?
Kind regards,
Dennis

It took a Snow Leopard a while but after 2 days it started working again. I've checked whether the connection was directly to the Extreme, but the connection actually went through one of the bridged Expresses.
I guys one just has to hope for the best ;-)
I've upgraded to Lion last week and backup works fine with the new operating system as well.

Time machine backup fails in my seagate 3tb external drive

Without any specifics it's impossible to assist you, however the best tool for debugging TM failures is using Pondini's Time Machine Troubleshooting guide.
Good luck.

Time Machine Backup Failed even though I still have 1.9TB of a 2TB Time Capsule. I am using Yosemite.

Time Machine Backup Failed even though I still have 1.9TB of a 2TB Time Capsule. I am using Yosemite 10.10.3 on an iMac (mid 2010)

The recent update in Yosemite (10.10.3) is causing some issues for some users.
Try a complete network power cycle as follows:
Power off each and every device on your network......modem, Time Capsule, computers, printers, etc......in any order that you want
Wait a minute
Power up the modem and let it run 2-3 minutes
Then, power up the next device that is connected to the modem an let it run a full minute
Then, continue to power up devices one at a time about a minute apart until everything is back up
Check the network
Wait for a backup to occur and report on your results

Time Machine Backup Failing For No Apparent Reason

http://i27.tinypic.com/313hg2c.png
I keep on getting that error whenever time machine tries to back up. I've completely reformatted my Time Machine drive, repaired the disk, and repaired my permissions all to no avail.
Anyone have any idea of what is going on? It just randomly started happening on day.

"Time Machine Backups" could not be unmounted (Disk Utilities)

Hi there,
I am having an error message when trying to back up time machine. Therefore I went to disk utilities and verified disk.. said it needs to be prepared. When I try to repair time machine, i then get the following message "The disk “Time Machine Backups” could not be unmounted". I tried again and then it says its been repaired. so when i tried a backup of time machine i get "time machine error. unable to complete backup. an error occurred while copying files to the backup volume"
I have installed "Time machine buddy" and I am getting"error reading system logs"
I have a mac osx 10.5.8. No antivirus or spotlight running that i know of.
Any ideas?

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode, see if external Drive can be repaired...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
