Time Machine backup causes network connections to fail

We have a simple network with OS X Server (10.6.4) + a 10.6.4 Mac client and a Windows XP client. For some time we have been suffering sporadic drop outs of the network connection from the iMac OS X client to the server: the shared drives just disappear and you can't reconnect.
I have now narrowed this down to a problem with Time Machine. By logging on as a user on the OS X Server I was able to observe that the user session on the server suffered the same problem sometimes and this ONLY happens when Time Machine is running - I think its always when Time Machine is backing up the server.
Its an absolutely infuriating problem and very disruptive for our business. I am loath to switch off Time Machine on the server but don't know what else to do. Has anyone else experienced this problem or got any ideas?

Yep, Rikakiah, seems you are right, I am not alone! There are two other threads here which discuss the same issue:
http://discussions.apple.com/thread.jspa?messageID=11539266&#11539266
http://discussions.apple.com/thread.jspa?messageID=11539227
From my testing it seems that the problem may be related to some interplay between Time Machine and LDAP - I say this because I can sometimes clear the problem and regain access to my shares by going into Workgroup Manager, removing the group assignments (which give access to the shares), saving the change, then adding the group assignments back.
This made me think that your solution should fix it, but unfortunately although I have excluded /var/db from Time Machine backups, I am still sporadically getting the problem.

Time Machine Backup causes system crash ...

After installing Mavericks my iMac 27" was very instable. Every now and then I noticed the spinning wheel and then step by step all functions were shutting down: 1. no menues, 2. no shortcuts, 3. no window change and so on. At the very end only swiping between desktops was possible. Tonight I just let him do hoping this will be fixed. I the morning I noticed the login screen, but without any function.
Actually I assume that the Time Machine Backup causes the problem! I switched it off about two hours ago and the system works perfectly until now.
I am using a TC 1. Gen. with Firmware Version 7.6.4 and Air-Port utility Version 6.3.2.
Routing and WIFI is both turned off on TC, I only use the TC for TM Backup and iPhoto/iTunes Media in a LAN.

Your problem is apparently caused by a third-party system modification. Reboot as usual (not in safe mode) if you haven't already done so. Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Next, do the same thing with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Next, this command:
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Again, one line. Finally, one more:
ls -1 /Library/{InputManagers,StartupItems}
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.

How to setting up new (June 2011) TC to do wireless time machine backup but not connected to network?

Hello. Just got new (refurbished June 2011, 2TB) Time Capsule. My building has a shared wifi network, and I'm assuming it's hard to join the network with Time Capsule and still be satisfied with security/privacy/performance. (Of course, if I'm assuming wrong, please let me know!)
My understanding is that I can use Time Capsule wirelessly to do Time Machine backups by switching out of my wireless network to - I assume - a new Time Capsule generated network(?). It's an extra step, but that beats connecting cables to the computer everytime I need to do backup. Basically it's like an external wireless hard drive that I have to join everytime the backup is updated, right? (Again, if there is a better way to go about doing this, please let me know.)
So how do I go about doing this? The setup manual isn't helpful (not at all).
Here's more detail if necessary. I have 10.8 Macbook Air (which I plan to upgrade to 10.9 soon) and my spouse is running 10.9 Macbook Pro. I am also assuming I don't have to partition Time Capsule, and when the Time Machine backs up, it'll figure who's who.
Thanks in advance.

Security is ok.. but performance is abominable.
The TC unfortunately has some design limitations that Apple imposed that makes it rather poor for anything but ethernet.
There is a couple of ways around the problem of sequential internet or backups.
1. Get a wireless bridge that is suited to your in-building system.. and plug that into the TC so it can take normal router settings .. This will give you double NAT but I doubt your in building system will be handing out public IP anyway. An airport extreme can do this. Although it is pricey for the same results as a $35 standard wireless bridge. All devices in your place will then get both internet and backup direct to the TC.
One flaw here could be the download limits.. if you have two connections do you get double the downloads.. ??
ie how many IP are allocated to you?? And is it divided between all of them or the more IP clients the more download bandwidth?
2. Use a USB wireless stick in the Mac.. these can be tiny little things now.. just buy Mac compatible ones.. use that for internet and use the internal (faster) wireless for local connections. there are some manual setup tricks needed here but nothing hard.

Time machine backup from network share

Hi there,
I was wondering whether there is a possibility to backup a personal folder on a network drive/share via time machine?
Anybody?
Pierre

This may help, in a backwards way. When I attempted to attach a Buffalo Technology NAS to my system and use it with Time Machine, I was unable to make it work. So I contacted Apple Technical Support on the phone and was elevated to talking to one of their Senior Engineers. He informed me that Apple designed Time Machine to only be compatible with USB and Firewire, and that Apple does NOT support use of Time Machine over an ethernet connection to an NAS. So he recommended I return my NAS and purchase a USB/Firewire type external drive for use with Time Machine. Which is what I did and have been happy ever since.
Hope this helps

Time Machine Backup to network shared drive.

Hi All,
I'm a relatively new Mac user (only had my MacBook Air (2010) since about Oct/Nov. I've been trying to get Time machine up and running so that it backs up to a shared 2TB drive on my wife's Windows Desktop Computer, but have only been partially successful.
Theese are the instructions I used: http://safalra.com/other/time-machine-network-drive/
Everything went super smooth and I was rewarded with a Time Machine Backup of about 94GB in progress when I went to sleep last night. However, when I woke up this morning I saw the error that something went wrong (same error I always see) and that I should try again later.
I restarted the backup on the Time Machine to see a backup progress of "43K of 32GB". It seems to be staying right there though. This seems to happen every time I try this. Has anyone had any success doing a Time Machine backup to a Windows Network drive?

The most recent error was along the lines of C3: ". . . an error occurred while copying files to the backup volume".
"The backup was not performed because an error occurred while copying files to the backup disk. The problem may be temporary. Try again later to back up. if the problem persists, use Disk Utility to repair your backup disk.:
Also, here's the 4 most recent log entries I have from Time Machine Buddy. They go newest (top) to oldest (bottom).

Using time machine backup on disk connected to airport extreme router?

So I've read a number of articles about using an external hard drive connected to the airport extreme base station as a time machine backup. The thing is that I'm writing this in august 09, most of the articles (which say the feature is officially unsupported) date about a year and a half ago. I'm wondering if there have been any developments since then.

I also have this problem -- it started about 2 weeks ago (around July 20?), possibly at the time the new Airport Extreme firmware went into effect. I have two separate Mac laptops that each use Time Machine to back up to different disks that are attached to the Airport Extreme (i.e., each laptop has its own backup-destination disk). Both were working flawlessly before (for more than 6 months); now, each one reliably drops the connection to the disk (produces an error message, and thereafter cannot re-connect to the destination disk until I cycle the Airport Extreme with power-off/on). I had hoped that 10.5.8 would help (the release notes talked about improved stability with Airport connections), but not so.

Can anyone access time machine backup files by connecting to time capsule by ethernet cable?

I operate an imac connected to a time capsule. It works great. My internet is connected to the time capsule with an ethernet cable and I access the internet on my imac using an ethernet cable connected to the time capsule. I can also connect to the time capsule using wireless.
A colleague of mine wants to connect to the internet and because of location issues the only convenient way is to let him connect to my time capsule using an ethernet cable. He can access the internet fine and he uses a windows PC. Now my question is, will he be able to access my time machine backup files if he connects to my time capsule using an ethernet cable? I have not given him my password.
Any help will be appreciated. I want to help him get online but I want to make sure he cannot access my time machine backup files.
Thanks

There are actually 3 passwords on the Time Capsule - assuming it has the same setup as my Airport Extreme Base Station.
One password for the WiFi connection.
One password to access setup of the device
One password for access to the storage drive - most people leave the check-box to just use the base-station setup password again.
And, as I said before, you also have the option to encrypt your TM backups. So even if somebody runs off with the device and breaks in to the disk, it will all be garbage without the TM password.
This is the screen as it is on my computer:
As you can see, to access my drive I have it set to use the device setup password.
Here is a screen shot of the other options:

Restricting Size of Time Machine Backup on Firewire Connected Drive

I've got an external 1 TB drive connected via FW800. Time Machine works fine, but I am also using this as a shared drive and want to limit the size of my Time Machine (to 600G for now) without having to formally partition the drive.
I've read all the tips on how to do this for a network attached drive using terminal commands to adjust the size of the sparsebundle. However, as this is a directly attached drive, Time Machine did NOT create a sparsebundle, just a folder called Backups.backupsdb. I tried, using Disk Utility, creating a sparsebundle image on the external drive but Time Machine does not see this volume when you select Change Disk under System Preferences, all it recognizes is the main hard disk.
What am I missing? Ideas? Thanks!

The only solution for a directly attached drive is to partition the drive. Note that a TM backup volume should be at least twice the size of the volume it backs up. A 600 GB partition would be adequate for a 250 or 320 GB hard drive.
It is possible to partition a drive on the fly with Disk Utility. but doing so will possibly result in loss of data depending upon how much data are already stored on the drive. For what you've describe it would be necessary to have at least 600 GBs of free space after the end of the existing data stored on the drive. This free space would have to be contiguous. Otherwise you would need to use third-party partitioning software like iPartition that ma be able to partition the drive without any loss of data, but you would still need 600 GBs of available space in order to create a new 600 GB volume.
Frankly, it would probably be better to have one drive devoted to backup, then buy another drive to use for storage needs.

Time machine backup on network drive

i have a netgear router with readyshare usb network drive i have a 2TB external hdd that i use for a central location to view files for both my imac 10.7.5 and multiple pc's windows 7 i currently have a external hdd connected to my imac just for time machine however this is only 320gb not large enough. was wondering if i could somehow make an alias of my current time machine bacup and place it in my network drive so that my backup would use this space too or maybe even make this time machine drive larger? or if i delete the connected time machine drive will the alias still be as is? i understand that i can just create a partition however if i understand the process correctly this would erase my files and the only option would be ExFat format from imac for windows then i would make and extended journal for use with time machine. i am not sure i want to do this because i dont know if i could reformat the disk with the default software still on thie 2TB drive. also i dont know if i could use it with all my pc's and imac. currently i can transfer files to either computer.

I have the exact same problem, but I am not using TM over a network... Only my local Mac Pro w/ a 600gb external drive. I recall back when I first got Leopard that time machine did in fact ask me if I wanted it to delete old backups after the drive filled up. Then one day it randomly decided to not delete old backups anymore... Instead displaying the same error message you get.
Can anyone help? (Besides telling me not to back up certain files, and to do it less often. Those are BS solutions! I want my entire HD backed up every time automatically erasing old backups when necessary. Is that too much to ask for?)

Time Machine backup to Windows Share Now Failing Verify

Hi Everyone - I have searched everywhere and can't find any help.
This is my situation. I have my TM backup to an SMB windows share and its been working fine for months. Two things changed recently: a) I installed Windows 7 on my windows box and b) I installed that TM update that provides greater reliability. Backups worked fine for weeks after both of these changes, but just this week backups failed and TM wanted to create a new backup. I tried to recreate a new backup, but it keeps failing with errors below. When I try to run a verify disk on the sparsebundle (with disk util) I always get errors, but of course, I can not fix the errors when the sparsebundle is on an SMB. I am currently running a chkdsk on the windows drive, but I don't think its damaged.

Can Time Machine backup USB Drive connected to Airport Extreme Base Station

I need a new N based wireless router. I would prefer to get just the $179 Base Station and not the $299 Time Capsule. I already have a nice external USB 500GB drive that I would connect to the AEBS. So, once I have this new wireless router/base station installed at home and I have the external USB drive connected to it, can my new Macbook Air with a USB connected 400GB drive be used to backup what is on the Macbook Air and also backup the 500GB USB drive info that is connected to the extreme base station?
Thanks
tj

I found this when searching Apple's web site but it is old, October 2007, and said it could not be done. Has this changed since then?
Here is what I found.
Mac OS X 10.5: Time Machine doesn't back up to AirPort Disks
* Last Modified on: October 26, 2007
* Article: 306833
Time Machine in Mac OS X 10.5 Leopard can be used to back up to many kinds of Mac OS Extended-formatted drives, but it does not support AirPort Extreme's AirPort Disk feature.
Time Machine can back up to another Mac running Leopard with Personal File Sharing, or to a Leopard Server volume, or an Xsan storage device.

Time machine backup causes system to crash

Hi, I had updates coming through on my macbook, and didn't realise until the next day that the power socket wasn't connected to my mac. When I tried to use my mac I kept getting an error, in that the computer wouldn't run at all, wouldn't start up.
I tried to use a backup from my time machine but I wasn't able to do so and retain all my information on iphoto mail etc.
When I try and reinstall from time machine I still get the same problem.
Is there any fix that I can do that will allow me to access these backups and run them?
Many thanks

I've been having problems over the last few days. It seems that it's stuck on 'Preparing Backup'. The menu bar icon shows activity all the time, but my last backup was over a day ago.
My system has been intermittently locking up as well. Sometimes it will unfreeze after a few minutes. Other times I'll have to power off using the power button. Not sure if this is related to Time Machine, but something's not right at the moment (maybe after the 10.5.4 update?)

Time Machine backup cause kernel panic crash

I bought the new iMac and transferred everything from my old G4. Initially everything worked great, but now I get a kernel panic crash when time machine runs a routine backup. Any ideas?
I am connected to a LaCie External Drive using the Firewire port.

It's could be something wrong with the setup of the LaCie, especially if it's new. Double-check it, per #C1 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
If it's old, it may be something wrong with the LaCie itself. Start by trying to Repair your backups, per #A5 in the same Tip.
Also, does the LaCie have it's own power supply?
Are any other external disks connected and being backed-up?

Time Machine backups cause error message "Disk No Ejected Properly"

I have a 2011 iMac using OS X version 10.9.4. I have had to change the external hard drive used with my Time Machine to get more storage. Every time the Time Machine backs up (every hour), I get the message "Disk Not Ejected Properly" Eject "FreeAgent GoFlex Drive" before disconnecting or turning it.
I am concerned about any damage that is happening because of this message. I researched this on this forum and other users had a similar problem. I tried 2 of the easier solutions: 1) make sure none of the boxes are checked in System Energy Saver (ie. put hard disks to sleep when possible, etc.) and 2) buy and connect a USB hub that has it's own power supply to keep the external hard drive powered constantly. Neither of these solutions has worked for me. I still get the message. So I have two questions. First, is damage being done to my computer because it "thinks" that I did not properly eject the disc. And, second, is there anything else I can do to stop this message besides not using the freeagent disc?

I had the same problem. it turned out to be a cable issue. Contact seagate for replacement cable.
