Air port can no longer detect Time machine or Airport express

I have a Time capsule (last generation) and an Airport Express. TIme capsule was set up a few months ago and working fine. Today I tried to Add the Airport express to the network to use it in another room. Everything semed to work OK and I got the message that the system is added successfully and waiting for AExpress to start. It took for ever so I opened the AIrport utility window again and try to re do i. I am not sure what I did wrong I can no longer detect either of my device with Airport utility to set up a secure network. MY Internet connection is fine and I can connect using the AIrport to other networks that Airport detects in the area fine also. I just don´t see the net work I configured or the devices. I sure would like to know how it got messed up and how to get out of this. I have tried unplugging and restating the time capsule etc as they suggest in Apple manuel. But I have not tried resetting the time capsule. Would this erase the back ups it already has? Please help.

Can no longer configure Time Machine

I upgraded to OS 10.5 from 10.3 a few weeks ago, Time Machine was working fine till today, when menu bar says Time Machine not configured, the Lacie disk I back up onto (which shows on desktop) now says Lacie and no longer shows the greenish TM logo (my HD on desktop still shows it okay) and when I turn TM on in prefs, it shows nothing to choose as my backup disk. I'm very confused...
Thanks in advance.

The preferences file may be corrupted.
Do a "full reset," per #A4 in Time Machine - Troubleshooting (or the link in *User Tips* at the top of this forum).
If that doesn't help, your backups may be corrupted.
Repair them, per #A5 in Troubleshooting.

RE: Time Machine - I have just replaced a drive on my drobo (to increase capacity). Time machine is backing up OK but I can no longer access Time machine back ups made before the date when I replaced the drive. Why?

Any help would be greatly appreciated.
Thanks

Hold down the option key and select

from the Time Machine menu in the menu bar. The menu icon looks like a clock running backwards. If you don't have that menu, open the Time Machine preference pane and check the box marked

Can I use time machine through airport express and an external hard drive?

I want to be able to use time machine remotely. I own a WD 1TB passport external hard drive. If I connect it to an airport express, will it backup my macbook pro?

Not sure what you mean by "remotely". Remotely on your network, or remotely over the Internet?
In either case, the AirPort Express does not support a hard drive. You would need an AirPort Extreme for that.
Trying to use Time Machine over the Internet is incredibly slow and unreliable. Remember, you are uploading. Upload speeds are often 10 times slower than download speeds with most Internet Service Providers.

Has anyone had had success with Time Machine and Airport Express 6th gen?

For the last six months I have attempted to use the Time Machine product to provide first level backup for my two MacBook Airs and iMac. Tryed a number of powered USB drives, tryed all of the current 10.8, 10.9 OSX software. The Time Machine product seems to work for about a month to six weeks and then fails with message about the file integrity or access problems. In all cases I can acess files on the drive and the only application that struugles with the AE usb drive is Time Machine.
You would think that if it works for a month it should work for a year?
I have purchased Carbon Copy Cloner and it seems to function without a problem and I think that I am probably better off with a once a day clone than a Time Machine with data integrity problems.
Has anyone had long term success with Time Machine and AE sixth gen?

You are connecting a USB hard disk to the new 802.11ac AirPort Extreme, not an Express, correct? If so, it works fine with both bus powered and self-powered drive enclosures, and I have no immediate explanation for what's going on.
You would think that if it works for a month it should work for a year?
Yes, besides the passage of time the only thing that is changing is the amount of available space on the backup volume, which could be a factor. Are you using separate drives for each Mac, or are they all being backed up to the same drive? If it's only one drive, is it partitioned or are they all sharing a single partition?
Are you sharing backup volumes with other, non-Time Machine files? That shouldn't cause the problem, but it's not a good idea.
What errors are being logged in system.log? Filter for backupd to find all Time-Machine related entries.

Networking time machine to airport express

i am trying to extend my wirelass to my barn.
i bought a 328ft cat6a patch cable and am planning to bury it.
i want to keep the time machine (A1355) in the house and have the express (A1084) in the barn.
before doing so, i plugged it into the back of my time machine in the second port (i have a microcell cellular booster plugged into the first) and then into the airport express.
ignorantly, i thought it would be that easy.
now, when plugged in, i can't use either network. i'm sure it's some setup procedure that i just can't figure out.
i unplugged so that i can beg for help. Bob Timmons, you seem to be the answer man. Please help.
thanks

Do you have another Mac there that is using the Leopard or Snow Leopard operating system, or a PC?
One of these computers will be needed to set up the AirPort Express A1084 that you have, since Mavericks (10.9.1) does not support the older versions of the Express.
Apple, of course, wants you to buy a new Express, which would provide about twice the performance of the older A1084....and it will ony take a minute or two to setup with your Mavericks Mac.

How can I get my time capsule and airport express (as a network extension) working properly together?

Hi,
I bought a time capsule a while back and connected it to my modem, and it seems to be backing up my hard drives but I can't tell if I'm getting my wireless signal from my time capsule or from the modem itself, which used to before I bought the time capsule.
It's bugging me because I'm trying to get my airport express to work as an extension to my network, and airport utility half the time can't pick up the express. I heard that it will only work of the time capsule is working as the base station,and I'm not 100% sure this is the case.
Also, how far can the airport express be from my time capsule for it to be picked up? I tried resetting it which helped to start with, but when I was setting it up to extend my network it just told me that there was an error and to try again, which I did with the same result.
Any advice would be much appreciated!
Cheers

Always do setups with ethernet.. setting up wireless via wireless is like cutting off the branch you are sitting on.
You do not need the TC in the network to do the setup.
Plug it by itself into the computer. Same with AE. But do each separately.
Give the TC a different wireless name.. like TC.. then you will know the TC wireless is separate and different to the main modem router. Simply allow it to be extended.
Plug it back into the main modem.
Now do the AE.. set it to extend the wireless of the TC.
When you do this check the signal level. The airport utility v5 has a full diagnostic of wireless client levels.. do not use v6 utility.. it is useless. The AE is placed somewhere in between the TC and the clients you want to connect.. it has to get decent signal itself to extend wireless. And there is no way we can tell you how far apart.. pick the half way point.. around about and suck and see. If it doesn't work move closer to the TC.
Count the walls the signal is going through.. about 15% signal loss for each one.. if angle is acute 20%.. floors are worse.. they might be 20-25%..

Time Machine and Airport Express

Got Time Machine to work with a Mini and my AEBS after the 7.3.1 upgrade. Did the full initial backup with no problem. However, I then had my Macbook backing up to the same AEBS and USB drive for several hours and the Mini's Time Machine tried and failed to do an incremental backup. Now I get a "disk is read only" error when I tried do perform a Time Machine backup and the error message recommends reformatting the drive. I'm now verifying the disk with Disk Utility.
1. Has anyone been able to have two Macs share an AEBS drive for Time machine without conflicts?
2. I initially set up each Mac on a separate partition on the USB drive. Is that recommended or should they share a partition?

In theory it should work, but I don't think you need to partition the drive as TM should manage each drive's backup separately.

Can I use my time machine backup to migrate my files to macbook pro retina from my macbook pro 15 inch?

I'm using a macbook pro 15 inch mid 2011 running on mountain lion.
I have a complete backup of my files on time machine. If I get a macbook retina, whats the best way ti migrate?
Can I use my time machine to restore to the new retina mac?
Thanks

I'd just use the Time Machine restore function when setting up your new machine. If you don't have the TB>FW adapter, how do you plan to connect to your external drive with your TM backup? You may have to resort to Migration Assistant - but it would be helpful if you had the TB>Ethernet adapter so that you could hardwire both machines to your router - going wireless is going to take a long, long time. If your external has a USB port, you could use that for a TM restore...

How can I use the Time Machine Backups from my Old Computer?

I have two months of Time Machine backups made using my old Macintosh computer which died and I no longer have. I have now purchased a new computer and am trying to use the Time Machine back ups from the original computer, but it will not recognise them. How can I get my new MacBook Pro to use the Time Machine Backups from my old Computer? I phoned the Apple help line and they said I cannot use them and would have to delete them. This sounds crazy if you can only use the Time Machine back up file with one computer and have to delete it when you buy a new Mac. Surely there must be some way to transfer ownership (not files) from an old to the new Mac?
Thanks
Richard

Thanks Kevin for the suggestion posted on MacOSXHints how to "Repair Time Machine after logic board changes".
http://www.macosxhints.com/article.php?story=20080128003716101
It seems as though I am not alone with my frustration with the way Time Machine uses the MAC address of a computer to tell one system from another. This means that if you have your Mac repaired with a new logic board, or replace your system with a new one, you can't resume backups where you left off. Reading through the readers who used the fix using Terminal, it appears that the fix does not always work. I contacted Apple again, but they were no help. Surely Apple should come out with a solution as more and more people use Time Machine/Time Capsule.
It is CRAZY that after a change computers or a switch in the computer logic board that you cannot resume your Time Machine back ups.

Can I have 2 Time Machines for 2 backups?

I have an external hard drive that I use for my time machine. Recently I've been having some problems with my iMac that are hard drive related. I wasn't able to repair using disk utility and had to erase and reinstall Snow Leopard and then transfer everything back from time machine.
After this I realize just how fragile this all is. I have many photos and videos of my family from years ago and was relieved that I had everything backed up. Hard drives are so inexpensive these days, I feel it may be wise to have another backup in the unlikely event both hard drives were to have problems at the same time.
Can I have two Time Machines? If not, what are my options?
Thanks for any suggestions on this topic.

Yes, but not simultaneously. You can switch the desired backup drive using TM preferences, but TM cannot backup to two drives concurrently. However, I would suggest not using TM for your second backup. Instead consider making a bootable clone on the second drive. You can then use a third-party backup utility to incrementally update the clone. Because this software is running independently of TM you can have both a TM backup and a third-party backup. With TM backing up hourly you can set the second backup schedule to backup weekly and/or monthly.
If something does go amiss with your main system drive, then you can boot from your clone in order to restore function to the main drive.
To avoid using up space on the TM drive be sure you add your second backup drive to the TM Exclude list.
Basic Backup
Get an external Firewire or USB drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. (Note: Most PPC Macs cannot be booted from a USB drive.) You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. Tri-Backup (Commercial)
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete FireWire drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

How can I get my time machine to allow me to recover files again? After upgrading to OS X, the time machine still backs up the files; but, I'm not able to navigate within the time machine or select any folders or files for restore.

How can I get my time machine to allow me to recover files again?
After upgrading MBA to OS X, the time machine still backs up the files; but, I'm not able to navigate within the time machine or select any folders or files for restore.
I've searched and can not find a solution to the problem that's being encountered.

Yeap that all makes sense now.
Do you only have the current backup showing in the TM display?? Won't it fill in the rest?
Over wireless are you waiting for the indexing to finish.. ??
Previous backup may not show for a couple of hours.
Long short of it.. Mavericks version of TM is a pain.
Sometimes it is easier to completely ignore the TM backup and do the restore manually.
I have posted the details here. See if this helps.
Can't access old files on time capsule

HT3275 can't backup with time machine

I can't backup with time machine and I do not receive any errors, time machine just stays in the 'looking for backup disk' mode and will not go any further. I went as far as buying a new usb backup disk to replace the old one and still the same issue occurs. I've tried using different usb ports on my mb pro and that doesn't work. No amount of restarting, ejecting discs or checking preferences helps. Disk utility states the drive is fine (even the new one), the permissions or sharing haven't changed.
My system is up to date with the latest updates, and this all just happened out of the blue one day. I suppose I could do a system restore but I'm afraid of losing my data; and I'm not 100% sure how to do that.
I'm running OSX 10.8.2, 2.3 GHz Intel Core i5, 4GB memory

There is good advice available about Time Machine. Go to Pondini's paper(s) before you do anything so drastic as a system restore.

Why can't i find Time Machine Back Up Device in Hard Drive

Why can't i find Time Machine Device in Hard Drive when i have plugged it already. White light just keeps on blinking.

Understanding and resolving a blinking status light
Here are the reasons that the status light may blink:
Your Time Capsule has detected that the internal hard drive has reported a SMART error
The base station has not yet been configured
The base station has been reset.
A new firmware update is available for the base station.
No IP address is available for the base station.
A Wi-Fi base station in Extended Mode is out-of-network Wi-Fi range of a primary Wi-Fi base station.
The WAN Ethernet cable is unplugged from the Wi-Fi base station.
The Wi-Fi base station lacks a path to the Internet (or local router).
Internet access may be temporarily unavailable from your Internet Service Provider (ISP).
A persistent, blinking, amber status light indicates that your base station may require your attention.
How to resolve a blinking amber status light alert
Launch AirPort Utility to determine why your base station status light is blinking amber.
AirPort Utility opens automatically if your Wi-Fi base station requires your attention. You may also choose to launch AirPort Utility at any time.
In the AirPort Utility window, locate your Wi-Fi base station and double-click on it to open the Summary window. Note: If you have more than one Wi-Fi base station, double-click on the icon for the Wi-Fi base station that has the amber circle next to it.
When the Summary window appears, double-click the amber circle to the right of Wi-Fi base station Status to open the Status window.
The Status window lists any conditions that require your attention. Respond to each item until there are no more items listed.
Eliminating the blinking, amber status light may require making changes to a specific setting, or putting a checkmark in the "Ignore" checkbox beside any option you don't wish to change. A checkmark simply tells the AirPort that you are aware of the issue and you have chosen to ignore it. For example, you may wish to leave your AirPort open without a password so that anyone can join your wireless network.
Click Update to apply your changes (the base station will restart).
After the base station has restarted, the status light should be green and not blinking. If the status light stays amber in color and blinks after the Wi-Fi base station restarts, you may repeat the steps above.

Can't backup with Time Machine: "sparsebundle is already in use"

Can't backup with Time Machine suddenly. Message says "back up disk image ...'/Volume/... /myMacname.sparsebundle' is already in use".
I have no idea what this means. Can someone please help? Please note that I recently upgraded to Mountain Lion.
Thanks.

Been having the same problem on mountain lion
Most forums say you must disconnect the users in AirPort Utility, but v6.1 no longer has this feature
So simply open “Finder” on the left under “Devices” you should see your “Time Capsule”. If not then it should be under “Shared”. Click on it and then select “Disconnect”. Then simply reconnect and that should be it
You can also restart the Time Capsule just by using Airport Utility.
Open Airport Utility and select the Time Capsule. Then up on the top bar select Base Station and click on Restart
Mine is now all working again
