Kerberos Time Skew Too Large

Hi Everyone,
Here's a strange one. Mac is bound to an Active Directory and is pointed to a domain controller for a time server. It is in sync with the DC to the second, but every two minutes, the following gets added to the system log :-
Jul 26 15:04:06 new-wave-films-imac DirectoryService[49]: Active Directory DS Plugin: Kerberos Time Skew Too Large. Check Date/Time!\n
Anyone got any ideas?
Thanks.

Not Kerberos related, but I ran accross other Time related problems...
Are the Time Zones & Daylight Saving settings the same also?

Reg: logon time is too large

hi all
i have installed oracle 10g on system ( p4 2x + 1gb ram ).
after installation when i log on to same system then it takes 20sec aprox. is there any solutions to reduce the log on time.
Thanks in advace

Ok. Then I would say it is now time that you put a logon trigger and start trace on your session. Analyzing the generated trace file may reveal vital information.

I have a 500 GB hard drive and a 1TB Time Capsule running on a MacBook Pro. It was all working well until the MacBook went in for a repair a week or so ago. Since then, TC will not perform a backup; instead, it says the backup is too large for the disk

Since having my MacBook Pro repaired (for a video problem) Time Capsule returns the following message: "This backup is too large for the backup disk. The backup requires 428.08 GB but only 192.14 GB are available."
I notice that there is also a new sparse bundle.
Since TC has my ONLY backup (going back about 4 years) I am reluctant to wipe it and start over fresh as I am afraid of losing files.
Is there a way of dealing with this?
I am using Snow Leopard 10.6.8

The repair shop likely replaced a major circuit board on your MacBook Pro, so Time Machine thinks that you have a "new" computer and it wants to make a new complete backup of your Mac.
You are going to have to make a decision to either add another new Time Capsule....or USB drive to your existing Time Capsule....and in effect start over with a new backup of your Mac and then move forward again.
For "most" users, I think this is probably the best plan because you preserve all your old backups in case you need them at some point, and you start over again with a new Time Capsule so you have plenty of room for years of new backups.
Or, as you have mentioned, you have the option of erasing the Time Capsule drive and starting all over again. The upside is that you start over and have plenty of room for new backups. The downside is that you lose years of backups.
Another option....trying to manually delete old backups individually....is tricky business....and very time consuming. To get an idea of what is involved here, study this FAQ by Pondini, our resident Time Capsule and Time Machine expert on the Community Support area. In particular, study the pink box.
http://web.me.com/pondini/Time_Machine/12.html
Once you look through this, I think you may agree that this type of surgery is not for the faint of heart. I would suggest that you consider this only if one of the other options just cannot work for you.

TIme Machine backup grows too large during backup process

I have been using Time Machine without a problem for several months, backing up my imac - 500GB drive with 350g used. Recently TM failed because the backups had finally filled the external drive - 500GB USB. Since I did not need the older backups, I reformatted the external drive to start from scratch. Now TM tries to do an initial full backup but the size keeps growing as it is backing up, eventually becoming too large for the external drive and TM fails. It will report, say, 200G to back up, then it reaches that point and the "Backing up XXXGB of XXXGB" just keeps getting larger. I have tried excluding more than 100GB of files to get the backup set very small, but it still grows during the backup process. I have deleted plist and cache files as some discussions have suggested, but the same issue occurs each time. What is going on???

Here is the log for the last failure. As you see it indicates there is enough room 345g needed, 464G available, but then it fails. I can watch the backup progress, it reaches 345G and then keeps growing till it give out of disk space error. I don't know what "Event store UUIDs don't match for volume: Macintosh HD" implies, maybe this is a clue?
No. It's sort of a warning, indicating that TM isn't sure what's changed on your internal HD since the previous backup, usually as a result of an abnormal shutdown. But since you just erased your TM disk, it's perfectly normal.

This is a completely normal start to a backup. Just after that last message is when the actual copying begins. Apparently whatever's happening, no messages are being sent to the log, so this may not be an easy one to figure out.
First, let's use Disk Utility to confirm that the disk really is set up properly.
First, select the second line for your internal HD (usually named "Macintosh HD"). Towards the bottom, the Format should be +Mac OS Extended (Journaled),+ although it might be +Mac OS Extended (Case-sensitive, Journaled).+
Next, select the line for your TM partition (indented, with the name). Towards the bottom, the Format must be the same as your internal HD (above). If it isn't, you must erase the partition (not necessarily the whole drive) and reformat it with Disk Utility.
Sometimes when TM formats a drive for you automatically, it sets it to +Mac OS Extended (Case-sensitive, Journaled).+ Do not use this unless your internal HD is also case-sensitive. All drives being backed-up, and your TM volume, should be the same. TM may do backups this way, but you could be in for major problems trying to restore to a mis-matched drive.
Last, select the top line of the TM drive (with the make and size). Towards the bottom, the *Partition Map Scheme* should be GUID (preferred) or +Apple Partition Map+ for an Intel Mac. It must be +Apple Partition Map+ for a PPC Mac.
If any of this is incorrect, that's likely the source of the problem. See item #5 of the Frequently Asked Questions post at the top of this forum for instructions, then try again.
If it's all correct, perhaps there's something else in your logs.
Use the Console app (in your Applications/Utilities folder).
When it starts, click +Show Log List+ in the toolbar, then navigate in the sidebar that opens up to your system.log and select it. Navigate to the +Starting standard backup+ message that you noted above, then see what follows that might indicate some sort of error, failure, termination, exit, etc. (many of the messages there are info for developers, etc.). If in doubt post (a reasonable amount of) the log here.

My mac will not copy more than one file at a time and gets locked up if the file is too large, my mac will not copy more than one file at a time and gets locked up if the file is too large

my mac will not copy more than one file at a time and gets locked up if the file is too large, my mac will not copy more than one file at a time and gets locked up if the file is too large

So now that you have repeated the same thing three times that doesn't make things any clearer at all.
You are copying files from where to where?
How are you attempting to copy files, software or click and drag?
Any other detail would be helpful.

HT3275 my time machine says the backup is too large but it should only be incremental

I have time machine trying to back up my mac (OSX10.6) to a time capsule but it gives the error:
"This backup is too large for the backup disk. The backup requires 240.66 GB but only 8.25 GB are available."
This time capsule is used for backups on multiple macs in our house and has previously performed a successful full backup for this mac. I thought it would just delete old backups to create space for new ones, but it doesn't seem to want to do this.
How can I fix this?

TM often seems unable to fix the old backups if the disk is used by several computers.. so this is not unusual.
You either need to delete the sparsebundle for your computer and start a fresh backup.. 240GB is a lot of stuff btw.. is it restarting or corrupted an old backup and needs to restart.
The alternative is to use a USB drive connected to the TC and use that as the TM target. A local external disk would do the same thing of course.

Time Machine - This backup is too large (incorrect sizes)

Good morning.
I'll start by saying that I've searched for an answer to this problem in these discussion forums and elsewhere on the internet. I haven't found this exact problem anywhere. So I apologize if this has been posted and answered already and I'd appreciate just a quick link to the solution if it's out there. So, with that said...
Got a Time Machine question I wonder if some of you folks might be able to help me out with. Here's the deal: I've got two internal hard drives, one 2.0TB and one 240GB (SSD, which I'm using for my boot/application disk). I back them up to the same external Time Machine drive, a 2.0TB Western Digital. I've been backing up both drives without a major problem for about six months (aside from an occasional "ran out of space unexpectedly" error, which I was able to fix with help from Pondini and his awesome Time Machine troubleshooting guide).
In addition to my main backup, I also have a separate 2.0TB Seagate that I keep offsite and bring in to update it every month or so. I'd just finished running my monthly update to that drive and switched back over to the WD drive. It refused to pick up where it had left off, which it does sometimes. So I sighed and reformatted the drive using Disk Utility to the usual Mac OS Extended (Journaled) format. I'm ok with having to start the backup from scratch if need be since I've got a redundant drive. Unfortunately this time things didn't go quite so smoothly.
When I went to do the first new backup to the newly formatted WD drive, it sat and spun for about a minute then gave me the following message:
"Time Machine couldn't complete the backup to "The Master's Watch". This backup is too large for the backup disk. The backup requires 2.00 TB but only 2.00 TB are available."
Okay, now you know as well as I do that no drive ever reports an exact 2.00TB of space available (on a 2TB drive). After a fresh reformat, my WD typically reports about 1.92TB of available space. And the maximum size of the backup (which, again, had been working just fine up until the swap back to the WD drive) would be in the neighborhood of 1.7TB (1.5TB on the internal 2TB and 190GB on the 240GB SSD). At the most.
I tried everything I could think of, including every suggestion I could find on Pondini's site. I re-reformatted, verified all disks involved, repaired permissions, chucked the TM preferences file, even ran some intensive scans on the backup WD using Drive Genius. Every test I ran came back and said the disk was perfectly fine.
So... for the moment I'm running temporary backups using Carbon Copy Cloner, which is definitely doing the job, but if possible I really would like to get Time Machine running on this drive again. I haven't ruled out the possibility that the drive may just need replacing (since it's... 3 and a half years old, I think?). But if there's anything that I may have missed that may get me up and running again, I'd really appreciate the insight.
Thanks for taking the time to consider my problem. Let me know if there's any further details about my system that may help track this issue down.

I would make this temporary situation part of a permenant plan that excludes TM from any critical duties.
I know this may not be what you want, (and I hear Pondini breathing over my shoulder), but I offer my opinion only.

Time Machine Error - The backup is too large for the backup disk

I have been using Lion (currently 10.7.1) on my MacBook Pro (13" - early 2011) since it was released. I haven't had any serious problems with it.
All of a sudden, I am getting an error in Time Machine. When it tries to run a backup, the error "This backup is too large for the backup disk. The backup requires 7.51 GB but only 630.1 GB are available." What gives? That's plenty of room. I have installed Logic Studio and a few plug-ins, so the 7.51 GB is probably right. The free space is correct as well. I can't understand what the problem is.
The backup disk is an external USB 2.0 drive with no other Time Machine backups on it or any other files. The folder "Backups.backupdb" is the only thing on the root of the disk.
I am reluctant to reset the Time Machine and lose all of the backups, but I will if anyone recommends it.

Hi Linc,
It is not working at the moment, as I have restored the original Lion image again; it has all my work and apps on it.
Many thanks for the info on the log, though. It tells a strange story. Here's the log from the last backup that worked to the first one that failed: --

I don't understand. For starters, I think it's a little wasteful that 3.5 GB has been used to back up 601 KB. That's the difference in free space on the backup volume between the two backups. That can't be normal, surely.
The only error is that mds[32] error, and from what I've read on forums, that seems to appear on backups that work perfectly.
Too weird. It looks like I'll have to reinstall Lion and all my applications again to get Time Machine working, or find another backup solution.

My time Machine keeps saying, "Time Machine could not complete the backup. This backup is too large for the backup disk. The backup requires 345.74 GB but only 289.80 are available." I have already excluded files. I have a 1tb external drive. HELP!!!

For over two weeks now I have been frustated and not having my TIme Machine back up to my 1tb external drive. I dont understand why now its a problem. It keeps saying
"This backup is too large for the backup disk. The backup requires 345.74GB but only 289.80GB are avialable. Time Machine needs work space on the bakup disk, in addition to the space required to store backups. Open Time Machine preferences to select a large backup disk or make the bakup smaller by excluding files." So I have already excluded almost all of my files, and even deleted the backup disk yet, that quote still keeps popping up. I am truly at a wall with this. I have a Mac OS X version 10.7.5. CAN SOMEONE HELP ME PLEASE????

Used Time Machine Backup Today- Now This backup is too large for the backup

Hey Everyone!
Some advice please,
My Hard Drive recently crashed. Fortunately, I've been using Time Machine. Apple Store gave me a new Hard Drive (for free), and I came home and restored to Time Machine. I am very impressed, and have lost no data or applications.
So now I have a problem. I can no longer back my hard drive, presumably because there were so many changes to the software today. I am getting This backup is too large for the backup volume. What is the easiest way to delete my old time machine backup and start from scratch with my computer in its current state? Everything seems to be working smoothly, so I don't see any reason to keep my old backups. Any suggestions? Is there any logical reason why I would keep the old backup?

Thanks Barry!
I called Apple (had to anyway for a new OS Leopard DVD) and he had me go into Disk Utility and choose Erase Disk (as you suggested). I didn't have to do any formatting.
The next step was to go into System Preferences and select Change Disk and set it to None. After that, he had me choose Change Disk again, and select the USB drive, and click Use For Backup.
Now it's backing up the new version of my computer. Problem solved. Thank you.
After having to get an brand new Hard Drive today, I highly recommend that everyone purchase some kind of external hard drive and run Time Machine regularly. Although the backups get large, I've never experienced such a pleasant experience getting my files back after a hard drive failure. This is awesome technology. I can't believe 95% of my applications still worked.

The datediff function resulted in an overflow. The number of dateparts separating two date/time instances is too large. Try to use datediff with a less precise datepart.

You'll get this error if the difference between the start and end date is greater that about 68 years due to the "second" DATEDIFF specification. Perhaps the dates are greater than the expected range due to a data quality issue.
Taking the advice from the error message, you could use minutes instead of seconds like the example below the version below. This could still result in the error of the difference is greater than a couple of hundred years, though. You might consider
validating the dates and returning NULL if outside expected limits.

Help needed with "Time Machine could not complete the backup" because it is too large

I'm receiving "Time Machine could not complete the backup" because it is too large for the backup disk. I have a 500 GB Time Capsule 802.11n (2nd Gen) and a MacBook Pro running on 10.6.8. I just replaced my laptop's original hard drive with a new 1 TB and restored that with what was on my Time Capsule. Now, I have no backups on my Time Capsule prior to the new hard drive. When I click get info on my hard drive, it states only 296 GB of the 1 TB is used. However, the Time Machine error message states that the backup requires 315 GB but only 221 GB are available. It has deleted all of my old backups, so I would think my Time Capsule should have plenty of room to backup the 296 GB on my computer. Is my old backup from my prior hard drive stuck on the Time Capsule and instead of Time Machine trying to just update those files, it is preserving the old hard drive backup separately and trying to make a new backup of my new hard drive using the remaining space? If so, how do I fix this? Any advice greatly appreciated.

TIME MACHINE Error: This backupup is too large for the backup volume ...

Hi Folks !
I have also my first problems with TM. It was running, the first time nicht&day to make the first backup and now seems the device to be full! This TimeMachineError was displayed:
This backup is too large for the backup volume. The backup requires 127.5 GB but only 46.5 are available. To select a larger volume, or make the backup smaller by excluding files, open System Preferences and choose Time Machine.
END OF ERROR Message
First thing > if I choose SystemPrefs/TM there is no chance to exclude file or folders the only dialog is for Volumes
Any Idea ?
Are the TM Preferences corrupted or why I cannot choose to define my backup ?
Ciao

When my Time Machine disk had only 50GB left, I got the message that it couldn't back up because it required 118GB to do so. Because there was, for some reason, only one day backed up, I deleted the backup files to start fresh. Now I am getting the message:
"This backup too large for the backup volume. The backup requires 1056.6 GB but only 929.4 GB are available."
Well, the backup only require 118GB a little while ago, and the initial full backup that I deleted was 880 GB. Nothing has been added to the startup disk, and a 400GB disk has been excluded to try to make this work, so this message can't be right.
How do I make this work? Do I have to keep reinstalling Time Machine every time I want to backup?

The message I get is: Time Machine could not complete the backup. This backup is too large for the backup disk. The backup requires 111.27 GB but only 42.1 GB are available.

I have a problem with my Time Capsule. The message I get is: Time Machine could not complete the backup. This backup is too large for the backup disk. The backup requires 111.27 GB but only 42.1 GB are available. As a result, my backups are no longer running. My umderstanding was that the Time Capsule would automatically delete old backups to make space. Can anyone help me figure out how to get my backups to run again?
