Time Machine does not start after external hard drive is connected

These are the iCloud storage options: http://www.apple.com/icloud/includes/lightbox-storage.html
Also bear in mind that:
1. restoring data over icloud takes time
2. iCloud is not designed as a replacement to Time Machine.

Time machine does not find my external hard disk.

is this because it is formatted ms-dos. it has been this way since i've had it and have used it to manually back up photos and other things, which worked fine. i see back up folders on there but time machine does not recognize it as its back up. can anyone enlighten me.

Your external HDD needs to be formatted HFS+ (Mac OS Extended - Journaled) for Time Machine to use it as a backup destination. You can move your current data off the drive and format it via Disk Utility.
You mentioned there are TM backup folders. Curious that you cannot access them. How are you trying to access them? Are you using the TM interface or viewing it via Finder?

Time Machine Backup not possible (normal external Hard drive)

Hi,
has anyone else had the problem that after the Lion upgrade its not possible to even really access your external time machine?
i have a 1TB Samsung HD103SI Media and when it tries to boot up it wont show in finder, i can see it in the disk drive utility and try to repair it but it only gets me an error saying i have to reformat that drive?
i hope this can somehow be fixed otherwise all my backups are gone

Hi,
Sorry to hear about your Issue...
Was your Samsung Formatted to Mac OS Entended (journaled) when you first started using it with TM...?
If so see the Troubleshooting Section in this Link to Pondinis excellent Tips on Time Machine...

If i have Time Machine backed up on an external hard drive, do i just plug the drive into another macbook pro and all my stuff is in the new computer? also, does it matter if the new computer is running Lion when the backed up info came from Snow Leopard

If i have Time Machine backed up on an external hard drive, do i just plug the drive into another macbook pro and all my stuff is in the new computer? Also, does it matter if the new computer is running Lion when the backed up info came from Snow Leopard 10.6.8?

No and Yes
Don't use TM for this purpose, clone your drive to an external, plug the external into another MBP and reboot from it. Please note that booting a machine that came with Lion may not be possible from a drive with Snow Leopard.

How can I get Time Machine to back up an external hard drive (iPhotos) that is attached to airport extreme base station. Note: Time machine is usb to macbook pro and external drive with iphotos is usb to airport extreme base station. Help please. Thanks!

Once you have the drive connected to your Mac, click System Preferences (gear icon) on the dock
Click Time Machine
Click Options
Be default, the hard drive will be Excluded from backups. Click the drive to highlight it, then click the "-" (minus) button at the bottom of the list to remove the drive from Excluded items.
The drive will be backed up on the next Time Machine pass
Everything above assumes that the hard drive has been formatted in Mac OS Extended (Journaled) as Time Machine will only backup drives in that format.

I am having trouble installing. downloaded Mavericks but it will not let me install to hard drive, says that is reserved for Time Machine. I have an external hard drive, but disconnected that before download.

I downloaded Mavericks but can't get past the install; it thinks my hard drive is reserved for Time Machine. I have an external hard drive but dis-connected that before download.
I have Time Machine turned off.

Check to see if you have a file name Backups.backupdb on the disk drive.
If the installer sees such a file it assumes that the disk drive is being used by Time Machine.

Since installing Lion, I have not been able to utilize Time Machine (does not recognize the back-up drive); my wireless mouse does not function properly; I have experienced unreasonable delays in the system. Is there a fix or upgrade coming?

Is there a fix or upgrade to deal with the many problems I am experiencing since I installed Lion? I can no longer utilize Time Machine (Does not see the back-up drive); my wireless mouse does not work properly; my iMac has slowed down considerably. I am reminded of having a PC machine again. Bummer!

Either downgrade to Snow Leopard or try reinstalling Lion.
Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Time Machine will not back up external photo drive

Time Machine will not back up external photo drive, slightly different format, one case sensitive the other not. How do I resolve. Bought new external drive same format as TM in the hope that I could copy the files from photo drive but that will not copy all files as it is saying file already there. Again the case sensitive issue...
Paranoid about losing 1Tb of photos all cataloged in LR5
Possible solutions I have looked at but not yet tried.
Use the new 2Tb drive to make a new TM backup then reformat the old 4Tb drive the same as Photo drive.
Then do a complete backup of all files and photodrive to TM.
A lot of work, USB 2, so if any one has a simpler answer I would love to hear.

What message did you get? You should never change permissions (or anything else) on a Time Machine drive -- TM does that for you.
Start with #C2 in the Time Machine - Troubleshooting *User Tip* at the top of this forum.
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 (especially the destination for the backups), what you've done, and the results.

Time Machine says both of my external hard drives require reformatting to case insensitive. What do I do?

I have been successfuly using Time Machine to back my iMac to an external hard drive (via usb) and everything has been fine for the last year. I have been using TM to back up to a HD called Terra LaCie via usb.
A week ago, my iMac hard drive was full--so I spulrged and bought a 6 TB external hard drive (Western Digital My Book-Thunderbolt). I set up the new Thunderbold HD to use RAID 1 (mirror) and copied most of my iMac hard drive over to the Thunderbolt HD.
I kept my working photographs (most recent) on my iMac and felt good to know my older photographs are on my new Thunderbolt hard drive.
For a few days, Time Machine seemed to work fine (backing up my iMac to Terra LaCie HD. I haven't been concerned with backing up the Thunderbolt drive (as I feel that mirroring is same as backing up).
Yesterday, Time Machine indicated the lastest back-up failed (for the HD called Terra LaCie). Now, when I go into Time Machine, the dialog box indicates the following message:
"Are you sure you want to erase the backup disk “Terra Lacie”? Erasing will destroy all information on the disk and can’t be undone.
The disk must be erased before it can be used for Time Machine backups because a disk you are backing up is case sensitive, but the backup disk is not."
When I open Time Machine to look at my external hard drives (I also have a third usb portable drive); two of the three drives indicate the following:
"reformat required; case insensitive disk".
The small, portable hard drive (that I'm also using) doesn't say it needs to be reformated (but my new Thunderbolt and my old usb HD both indicate the same message (above).
What should I do? I just spent days transferring my photographs from my iMac to my new Thunderbolt. Should I just not use Time Machine any longer and work from my Thunderbolt drive?
Am I to understand that my iMac suddenly become case sensitive? Sorry if this was too much information about my hard-ware set-up.
Any help someone can provide me would be greatly appreciated. I suppose I need to understand Time Machine and perhaps my Thunderbolt better.

Hi BDAqua,
Bravo, you helped me solve my problem.
The Case Sensitive Disk was the small portable hard drive that I was using termporarily.
I just disconnected it and I started TM machine and everything seems to be working just fine.
Thank you very much!!!!

Time machine can not select my internal hard drive any more.

Hi all
Time machine can not select my internal hard drive any more. I only can back up external disks. Does anyone know how to fix this?
All answers are much appreciated

I don't know the answer but I have the same thing happen. I have two external drives I use for backup. Sometimes it can see one and sometimes another. Then sometimes it can't see either one. I will take one out for a while then plug it back in and then it may see it. Maybe it's a cable issue or something but I will be curious to hear what someone more knowledgeable says.

HT201250 Time machine back up using a external hard drive connected to the Airport extreme

How can I setup a time machine back up using a external hard drive connected to the Airport extreme? Even better for time managment purposes I want to use the Eithernet Thunderbolt connection for the first back up and then through the wifi there after for daily routine Time Machine back ups.

You can attach a hard drive, but Time Machine backups to a drive at the USB port at the AirPort Extreme are not supported by Apple, so it's not possible to say what your actual results might be.
If you decide to try this, it would be wise to have a secondary backup plan in place as well.

Thank you in advanced.

Hi,
How did you clone the HDD ? One-for-one or different method ?
Regards.

HT201250 I have thousands of pictures on my Mac. If something happens to my Mac I don't want them lost. I do time machine back ups to an external hard drive once a week. Is this good enough for making sure my pictures don't ever get lost?

Purchase a couple of these when they go on sale.
Start burning all the photos onto DVDs.
At least you'll have all your photos if your computer, time machine or any other backup you use goes bonkers.

Can Time Machine back up a second external hard drive that is attached via usb to a Time Capsule?

Can Time Machine back up a second external hard drive that is attached via usb to a Time Capsule?
I have a iMac with 10.7.4

I want to back up the data on the external Hard Drive that is attached to the Time Capsule to the Tim Capsule using Time Machine.
Thanks for the clarification. Unfortunately, that will not work. You will need to connect the drive directly to your Mac if you want Time Machine to backup the drive to the Time Capsule.
