Time Capsule Installation Producing Different Errors

I just bought a 1TB Time Capsule to go along with my 24" iMac.
I already have a home network where my Desktop Mac, Desktop PC and Laptop all connect through the net and to each other through a D-Link Wireless Router.
On the Time Capsule papers, it is recommended to connect the Time Capsule with the router.
1) Can someone explain why this should be done?
I can understand the benefit of a possibly stronger signal but is there another reason to connect the Time Capsule to the Wireless Router (via Ethernet Cable)?
Anyway, I have connected the two together and then I turned on the Time capsule for the first time.
Let's forget about Time Machine (Backup) for now.
First thing it did was ask me to do a firmware update which I did.
Then it asked me to choose one of three choices (through Airport Utility):
1) I have a wireless network and want to add Time Capsule or replace an existing device on my network.
2) I don't have a wireless network and I want to create one
3) I want to connect Time Capsule to my computer or network using Ethernet.
I chose option 1 as I figured that I'm ADDING something to my network or that I may be replacing my router in some alternate sense.
The next screen asked me 3 more questions...
1) I want to replace an existing base station or wireless router with Time Capsule.
2) I want Time Capsule to wirelessly join my current network
3) I want to connect Time Capsule to my network using Ethernet to extend my current network or create a second network.
This is a harder set of questions as in one way or another, all 3 seem to fit my setup.
I wish to connect to the Time Capsule and then the Wireless Router through all my computers. The Wirelss Router is connected to the Time Capsule through Ethernet so option 3 may seem valid.
Option 1 is valid if it is deemed that I am actually replacing my wireless router now with the Time Capsule.
I chose option 2 as that was the most simplest option.
I don't know if this is correct but this is my understanding that I'm just JOINING the Time Capsule to my current setup.
Then it asked me to select the Network Name. So I selected the Wireless Router name from the Drop Down Box. I hope this was the right thing to do.
Once I chose the wireless router, it asked me to select the WEP key but it gave me several choices:
WEP 40 bit
WEP 128 bit
WEP (Transitional Security Network)
Which one do I choose for a standard 10 digit hex key?
I chose 40 bit first time around and I chose the Transitional Security Network 2nd time around.
I entered my WEP key and then continued to update the settings.
It did it's thing and then it restarted the Time Capsule but when it came back on, it said that there was an error setting up the Time Capsule.
I have checked the cables and made sure everything is connected properly.
Can someone please help me understand the logic behind all of the choices above and also why I am unable to set it up? How can I get passed this error?
I have reset the Time Capsule several times now by pressing the reset button for 5 seconds.
Appreciate the help,
JH

Any help on this at all?

When doing a restore with Time Capsule, I get -8003 error; restoring nothing

Hi,
When doing a full restore with Time Capsule, I get -8003 error; restoring nothing. This happens with all recent backups. Also after doing a verify/repair of the TimeCapsule disk.
This is a dissaster for my originals (my Ableton Live projects). I am very dissapointed in TC and TM at this moment, because I trusted my backup system in combination with my MBP fully.
Please help?
Best regards, Tom

Hi Pondini,
Sorry for the late response, but the problem was something else and were two separate ones.
Somewhere along the way the TC backup couldn't find backup to the original TC volume, that's why I let TM backup towards my user volume named 'Tom'.
When I wanted to restore the root of my drive when selecting the diskname and 'Restore' in any point in time, this resulted in error -8003 in the activated TimeMachine.
Then I tried to do it via the recovery OS and even via the original OSX DVD. Both not enabling me to select the TC volume named 'Tom'. Then I remembered that I first backed-up onto the original 'TimeCapsule' volume/partition. When I copied the sparsefile to the 'TimeCapsule' partition, I was able to recover the entire disk using the recovery OS.
All my files are backup and I am a happy Mac user once again :-)
Thanks & Regards, Tom

Time Capsule WDS trial and error--working now

*{ I }*
I consider myself an expert in using Mac computers and Mac wireless systems although I am no hacker and no programmer by any stretch of the imagination (although I did teach myself how to use HyperStacks way back in 1990!). Although Apple overall provides a relative ease of use for computer technology, setting up a WDS network under b or g mode is still not always perfect. In this post, I relay my experiences of using a new Time Capsule to join an existing WDS network in 802.11g mode. It took several trials and errors and there might still be some glitches but for now it seems to be working.
note: you might want to skip to the last section roman numeral five if you want to skip the "travels with Conal and his Time Capsule" and see what my most helpful hint is.
*{ II }*
WDS stands for Wireless Distribution System which is when you use wireless routers to extend the range of your networks using a wireless method rather than linking each router by long cables. In the ideal situation, you would link the routers by cables but in a home situation one may not be able to have unsightly cables hanging everywhere.
My previous WDS system looked something like this:
DSL Modem == Extreme ~~ Express1 ~~ Express2 ## laptop
Key
== represents wired connection between routers
~~ represents wireless connection between routers
## represents wireless connection to a wireless device that is not a router (eg., laptop)
Extreme = Airport Extreme, the previous generation that looked like a saucer (or humourously I have heard called a "boob-style" station.
Express1 and Express2 = Airport Express, the previous generation that only could broadcast in b or g
My laptop usually connects to the network from Express2 because that has the strongest signal in my room.
*{ III }*
When I received my Time Capsule, I wanted to replace the existing Express2 and make Express2 simply become a wifi client (not a router) so that I can still use it for AirTunes and not to have it broadcast router signals. The reason for this is because Express2 and Time Capsule reside in the same room and aside from the redundancy of network signals, I don't know if having two wireless routers in such close proximity to each other would cause havoc on my network performance. I wanted the network to look like this schematic:
Extreme ~~ Express1 ~~ Time Capsule
I unplugged Express 2 and took it to the same location as Express 1 and Extreme 1. Then I plugged in Time Capsule. The idea of putting them in close proximity for set up was so that they could properly configure each other.
I opened up Airport Utility and it saw all four of my routers. I went through the wizard for Time Capsule selecting the option for it to replace an existing router. When all configurations were automatically set Time Capsule rebooted and in about two minutes or less, Airport Utility tells me there was an error configuring the Time Capsule. I knew immediately then that I had a few long hours ahead of me.
After that first failure I tried these various ways:
1. retried the wizard automatic way (never worked for my setup which albeit is not the simplest of network setups is neither the most complicated)
2. performed a manual configuration whereby I added the Time Capsule Airport ID to Express1 making Time Capsule a remote router of Express1; then I manually added Express1 to TimeCapsule as a router that it should connect to (that didn't work for some reason)
3. finally I got out the ethernet cable, hard reset Time Capsule, plugged in ethernet cable from laptop to TimeCapsule, and the manually added the Airport ID to Express1 and vice versa.
Note that I went through trial #2 several times fiddling around with other various WDS configuration etc. Finally what really worked for me was #3. I find that despite that I should be able to configure a new router wirelessly, I was not able to do so with success. I had to do it in a wired ethernet fashion.
After that was done, all was set. Well, almost because I still had to reconfigure Express2 so that it no longer would work as a router but as a wifi client.
*{ IV }*
Now my whole network looks like this
DSL Modem == Extreme ~~ Express1 ~~ TimeCapsule ## Express2 ## laptop
Note that Express2 and my laptop are actually both connected wirelessly to TimeCapsule. I am unable to draw it in another way due to the limitations of using linear text to represent parallel items.
*{ V }*
So, my advice for those who are having trouble with configuring Time Capsule or other wireless router, sometimes you might want to try plugging in an ethernet cable so that not only is the connection more solid but that pretty much continual contact with the router is available.
I realise that WDS in 802.11n is configured slightly differently and so perhaps WDS setup has improved but as it stands in 802.11g and 802.11b in the way Apple has implemented it, I would not suggest someone below the level of expert doing it. It can be very baffling, confusing, and irritating. I would never ask my father to try to set up WDS on his own even though there is a wizard for it. I know some people (like Chris Prillo) has had no problems with the wizard, but I have always had problems with the wizard. Not only did I have problems with it when trying to get the Time Capsule to replace an existing router, but when I set up my original WDS network I also couldn't use the wizard to set it up. It kept giving me errors.

You are over complicating things. I have a Time Capsule (TC), AirPort Extreme (AE) Base Station and AirPort Express (AX) all working flawlessly with WDS.
Make sure to write down the MAC addresses of the TC, AE, and AX. You will need them to configure WDS.
Using the AirPort Admin util configure the TC. Turn on WDS and set the TC to be the main.
Using the AirPort Admin software configure the first AX. Turn on the WDS and set it as a remote client of the TC. You will need the MAC address of the TC.
Using the AirPort Admin software configure the second AX. Turn on the WDS and set it as a remote client of the TC. You will need the MAC address of the TC.
You may have to reboot each device after each config change.

Copying data from a Time Capsule to a different Mac

After having searched the forums for quite a while and still not finding the correct answer, I decided to share my solution for this very specific scenario: I have a Time Machine backup onto a Time Capsule from a Mac. Let's call it Macintosh A. So, for whatever reason, Macintosh A is out of commission—perhaps it's in the shop, or it experienced a hardware failure, whatever—and you want to get data from the backup onto another Mac, we'll call it Mac B. Here's how. First off, these instructions assume a few things:
You know how to navigate files and folders on the Mac
You are running OS X Mavericks (the procedure will be similar in other versions of Mac OS but these specific instructions are for Mavericks)
You are on the same Wi-Fi or ethernet network as the Time Capsule
You are viewing files and folders in column mode (wherever I say click on a folder, it translates to double click if you are in icon or list mode—if you're using cover flow, stop and change to one of the other actually useful view modes)
You know the device password to your Time Capsule (this is usually different than your Wi-Fi password)
Wherever you see Macintosh A in the instructions, substitute your backed up computer's name (I know, but this trips up a surprising number of people...)
Make sure that when you set up the Time Capsule via Airport Utility, you tick "Enable file sharing" (see the Disks tab in the Airport Utility configuration window). Next, while in the Finder, select "Go: Connect to Server..." and in the subsequent dialogue box, click on "Browse". This will open a Finder window listing the available volumes. Click Network and your Time Capsule should appear as one of the options. Click on it and you'll come to a connect dialogue. Click on the "Connect As..." button and it will open a password dialogue box (this may take a bit of time, especially if you are connecting over Wi-Fi). Enter your Time Capsule password and click "Connect". Click on the Data folder and you will come to something called a Sparse Bundle. It will have a name something like this: "Macintosh A.sparsebundle". This is simply a type of volume that you can connect to from your Mac. Double click on it. Depending on how you have configured your Finder, your Time Machine Backups icon may show up on the Desktop or simply in the Finder window Sidebar under "DEVICES". Once you locate this, navigate to the "Macintosh A" folder and you will see a series of folders named by date. Now you can navigate through those folders to find the specific files that you want to recover. Once you locate those files, simply copy them to your Mac (Mac B, in this example).
The abstruse nature of the Time Machine and Time Capsule backup system is daunting. And let's not forget that when you are trying to restore files, it's often because there is some sort of computer failure and this is stressful enough without having clear cut instructions on how to restore files. And often enough, people don't want to restore their entire system—they may just want to access certain files. This is for them.
Good luck and happy restoring!
Albeeboy

Take a look at Migration Assistant, in the /Applications/Utilities folder. You can use a Time Machine backup to restore your data files.

Access your TIme Capsule from a different network?

Okay, I've been looking everywhere for a guide or how-to to do this, but my searches have been more or less fruitless, coming across outdated, incomplete or incompetent so-called "guides", so I thought I'd finally post a question myself, and see if anyone has actually been successful in doing this.
What I want to do is be able to do is access all the files stored on my Time Capsule from anywhere (using accounts and/or passwords), provided I have an internet connection. I use my Time Capsule as an external hard drive, and it's great at home, but I have a lot of music, movies, photos etc that I don't have space for on my MacBook, so being able to connect to my Time Capsule from other locations would be awesome. I have seen many guides and how-to's, but no matter how closely I follow the steps, it never seems to work. If anyone has had any success using one of the guides, feel free to post the link below.
I am running the latest firmware on the Time Capsule (7.5.2) - the serial number is 6F01208ZAQG if that helps, the latest version of Airport Utility (5.5.2), my Time Capsule is connected to the internet via a Thomson TG585 v7 router (via Ethernet cable), I am on a MacBook running OS X 10.6.5, which is connected wirelessly to the Time Capsule, and if it makes any difference I am in New Zealand.
Any information would help, but if you're going to say "it doesn't work" or something not-so-helpful like that, could you please give a reason? I'm tired of you pessimists shooting everyone down.
Thanks in advance,
Ryan

Welcome to the discussion area!
It's been some time since I have used the "feature" to access files on the Time Capsule over the internet, so I can't remember all the details from 12-18 months ago. Some specifics I do remember:
1) You must have a "static" IP address for your internet service from your ISP
2) You must use a simple one port modem that will allow the Time Capsule to be the "main" router on the network
3) You must use Mobile Me from Apple to set this up
However, I notice that Apple no longer talks about this feature on the newer Time Capsule literature online, so that might be a hint that it is no longer being supported.
When did have it working, even small file transfers took forever. The connection, if I was using wireless, was often lost before transfers could complete.
I haven't tried the "how to" in the article below because I no longer travel for my job, but it might be worth a look for a different approach if Mobile Me is no longer providing this service.

2TB Time Capsule getting "An unexpected error occurred. Try again" error

Hi,
I have been using 2TB Time Capsule as wireless hotspot and for Time Machine for about one year but all of a sudden it stopped doing backups. When trying to do a backup Time Machine said it couldn't find a disk to make the backup.
Airpot Utility is still able to see my time capsule:
However when trying to configure it using the utility first it spends some time at this point:
And after 2 or 3 minutes I get this error message:
Things I have tried with the same results:
- Setting my network preferences to change the "Configure IPV6" value on TCP/IP advanced setting to "link-local only" as suggested by a post I read but no luck.
- Also tried doing a hard reset of the device by pressing the reset button with a pen for 5 seconds until the led blinked fast. But I get the same error when using the Airport Utility.
-I even tried doing a factory-reset by unplugging the Time Capsule from power, pressing the reset button with a pen, plugging back the power and waited until the LED blinked fast. But I got the same error message when trying to configure with the Airpot Utility.
There are a few occasions (about 10% of my tries) where I am able to get one step further: I get to the point where it asks me for a password and for a name for the Time Capsule, however when clicking next it seems that it starts to configure some things and I even get internet access via the Time Capsule, however the Airport Utility shows the same unexpected error message after a few minutes. In this scenario Time Capsule works fine as access point, but it the disk still shows as unavailable for backups. I haven't found what conditions make me be able to get to this single further step. It seems to be related to the hard-reset. But it is confusing because most of the times I do the hard-reset procedure it doesn't allow me getting to the password and name setting step. 90% of the tries get stuck in the previous step.
Any thoughts about how to solve this problem? I am worries about not been able to backup my Mac. By the way, my Mac is a MabBook Pro running Mountain Lion.

There is some bug with the TC disk and Mountain Lion..
Look at Pondini section C .. much of it relates to later OS .. Lion and ML.
Some things are obvious and others are just a mess.
Note C9.. that is important. Use short names.. no spaces and pure alphanumeric.
http://pondini.org/TM/Troubleshooting.html
Try manually mounting the disk.. in Finder.. use Go, Connect to server.. and type in the address,
AFP://TCname or TCIPaddress (replaced with actual name or actual IP). eg at default, AFP://10.0.1.1
Any failure to connect try another factory reset and use ethernet.. and do it in full isolation from the network.. ie just the MBP and the TC with ethernet between them.
What version is the TC.. A1xxx from the base please??
What firmware revision?
Using v5 utility can sometimes get around things but you cannot use it on Gen5 TC.
You can load v5 utility into ML with a trick.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
For screen shots see this post.

Can't back up to time capsule, repeatedly get message error occurred while trying to copy files to the backup disk

I have just installed a time capsule on my new IMac.
I have set it up with ethernet connection to my modem and to my IMac
Every time I try to back up I get an error message about not being able to write files to the backup disk; I have reset it, re-booted it and done everything else I can think of.
Does anyone have any suggestions on remedying this problem?

Time Capsule Installation on VMware Fusion Windows xp and Mac 10.5.2 sides

I've got the Time Capsule w/ time machine working on the Mac side of my laptop, and yet am avoiding a second attempt to load / install the same on my XP side due to the first time I tried, it didn't work and I had to go back and re-install it on the Mac side.
I'm assuming that the currently working 'Time Machine' is only able to see and back-up, via the Time Capsule, the Mac side of the hard drive? Although, if it sees the whole drive, both XP and OSX sides, then all is good, and my windows based data is being backed-up.
Maybe the Time Capsule can only work with windows as an external drive,
and yet hoping it can also work as a semi automatic back-up disk.
Appreciate any insight, advise and/or references to material that would help.
Thanks

I asked this very question on another forum, as I had received differing answers previously. Here is the link to my question and to the answers I received, which seem pretty dispositive. http://forums.macrumors.com/showthread.php?p=5305380#post5305380
As you will see, the short answer is that the Win side is not being backed up, but how you should configure your TM backups of your Mac side depend on whether or not you first partitioned with Boot Camp and then installed VM Fusion, or whether you installed Fusion without Boot Camp. (I now use Windows Live OneCare to back up the Win side to the TC, although configuring it to work with TC was a nightmare I care not to have ever to repeat.)

Time Capsule initial back-up error

The back-up was not performed because an error occurred while copying files to the back up disk.
What are the solutions to the above error message? Disk Utility verifies the time capsule disc as okay, I have no external devices attached -- and am using an ethernet cable to carry the back-up data to the time capsule as it is the first back-up. About 4 gig gets across then the operation quits. I am guessing there is a rogue file which is tripping up the back-up. All thoughts gratefully received.

Not one of Apple's more informative messages.
You're right; most likely, there's a problem with a file on your system. See #C3 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results.

Time capsule aborting backup with error message

My Time capsule has worked properly for a year but has now stopped. I keep getting an error message which says "The backup was not performed because an error occurred while copying files to the backup disk" and then continues with "The problem may be temporary. Try again later to back up. If the problem persists, use the Disk Utility to repair your backup disk".
I've erased the disk, reconfigured it and it appears to working correctly. However, after backing up anything from 4gb to 20gb (of 93gb to back up) it stops with that message.
The airport utility I am using is version 5.5.1 (551.19) and the Time Capsule is 7.4.2. I think there's another version for this but the 'Check for updates' says nothing to update.
I have now connected via ethernet in an attempt to rule out any wireless issues, although the wireless network is functioning perfectly.
What can be the problem here?

Hi, and welcome to the forums.
I hate that message -- there's no clue about what to do when that doesn't work.
It's most likely a corrupted/damaged file on your internal HD. See #C3 in Time Machine - Troubleshooting.

Time Capsule not producing wireless signal

We have a time capsule serving as our main wireless for the house and it recently stopped producing a wireless signal and has a solid amber light. I've tried leaving it unplugged and I've tried resetting the device. Neither of those plans had any effect at all. How can I fix this?
I believe my wife bought this in 09 and its got a 2 TB hard drive. Not sure which version that makes this.

Unfortunately, a solid amber is light is not a good sign.
Try a complete Factory Default Reset on the Time Capsule using the steps below. This procedure will not affect any of the data that you have stored on the internal hard drive.
Power off the Time Capsule for 15-20 minutes or longer
Hold in the reset button on the back of the Time Capsule first, and keep holding for an additional 9-10 seconds while you simultaneously plug the power back in to the Time Capsule
Release the reset button after the 9-10 hold period and allow a full minute for the Time Capsule to restart
The Time Capsule light should normally stay solid amber for about 30 seconds and then change to a slow, blinking amber light, indicating that the Time Capsule has been reset and it can now be reconfigured.
If you try the Factory Default Reset a few times and the light stays solid amber, unfortunately the hard drive has failed, or there is an internal power supply issue with the Time Capsule.
You should take the Time Capsule to an Apple Store.....if you have one in your area.....or contact Apple Support directly to discuss your options.
http://www.apple.com/support/contact/
If the Time Capsule is out of warranty or not covered by AppleCare, Apple will not offer repairs but there are some shops that specialize in this type of repair. See this link for more details:

2TB Time Capsule getting "An unexpected error occurred. Try again" error after a hard reset

Hi,
I'm working with a brand new 2TB Airport Time Capsule and after I performed a Hard reset as expalined in the forums I'm not able to configure it any more. I receive "An unexpected error occurred. Try again" from the AirPort Utility.
I'm running Mavericks in my Mac and I'm not sure what else to do. Any suggestions?

Completely isolate the Mac and the TC from the network.. plug the TC lan port by ethernet to the Mac.
Factory reset the TC.
Factory reset TC Gen 5 or AE Gen 6
Unplug your AE/TC .. hold in reset and power the TC/AE back on.. without releasing the reset.. wait until status led flashes rapidly.
Make sure in the ethernet settings you have ipv6 set to link local and the dhcp set for ip. It should give you an address of 10.0.1.2
Open the airport utility, using the top menu.. File, Configure Other.
Type in the address, 10.0.1.1 .. no password is required at this stage.
Click ok and the main setup will open.
Set all the names short, no spaces and pure alphanumeric.
Set the TC to the right mode .. dhcp+nat for router or off (bridge mode) for bridge.
Set wireless to create a wireless network.
No luck then the TC is faulty and needs to be returned.

Time Capsule suddenly producing very slow internet connection

I use my TC as a router and back-up. The internet connection is suddenly very slow and unable to load some more complex web pages. I plugged the cable modem directly into my MacBook Pro and the connection is fine, so I do not believe it is our signal from the internet provider. Yesterday I was unable to locate my TC back-up files on my computer, but today I could.

Same scenario. firmware 7.7.3. Drops from 8Mbit direct to 0,2Mbit through the Time Capsule (latest version 2TB).
Have a try naming the two wireless bands differently.
ie TC24ghz and TC5ghz .. then force the Sonos to use 2.4ghz and force the computer to use 5ghz.. do you get any improvement??
If not the TC could be faulty on the wan side.. to test you need to do actual file transfer tests between the client and the TC.. copy a large file to the and from the TC hard disk.. it should go at up to 50MB/s over ethernet and around 10-15MB/s over wireless.
The WAN issue with some modems is difficult to track down.. if the TC is new return it.. or still in warranty at least get apple to test it.

Do the new Time Capsules have a different design?

Having had my TC die, but out of serial number range for the paid repair, I did the job myself and it now works again - but for how long?!!
The fault was obviously overheated capacitors, the same as the articles on the internet show, so I'm not sure whether it is sensible to buy a new TC.
If the basic flaw has not been fixed with a new design that avoids these capacitors overheating then the same thing will likely happen again.
Does anyone know if the new ones have been redesigned?

Millions of later generation Time Capsules have been sold and we hear of a failure having to do with the power supply every once in while. Based on that, my opinion would be that the design is just fine. If my memory and observations are correct based on forum posts, I would also say that over the last 18 months, a higher percentage of AirPort Express devices fail than Time Capsules, even though the Express is a much simpler device.
Having looked inside at both an early generation Time Capsule and a later generation Time Capsule, there are definitely different types of capacitors used. Not having a schematic of the circuitry, I can't tell you whether there were any design changes in later versions in the power supply section or not. That would be a question for the Apple product engineers.

Failed backup with Time Capsule, how to correct Error 11?

I just recently bought the Time Capsule and started using it with my MacBook. It performed the initial backup just fine, but then about two weeks after, I started getting failed backup messages. I recently checked this discussion forum and tried some of the suggestions with no success. So then I launched Consule (like one of the discussion threads recommended) and typed backupd and copied and pasted what was recorded when I tried to run the backup again. Can anyone help me make sense of what is going on here and what Error: 11 means and how to solve it? Thanks.

According to your logs Time Machine is choking on the files labeled
tyetvrge.default
It is found by navigating to the "Profiles" folder found here
+/Users/apple/Library/Application Support/Firefox+
Open Time Machine Preferences and click "Options...". Then drag the "Profiles" folder into the Exclusion List. then try backing up again.
Let us know if this resolves your issue.
Cheers!
