Exactly what does "Remove Disk" in Time Machine do?

I am concerned that my current TM disk is having issues. I would like to use another drive to make a TM backup but I am not ready to toss the relationshop the current disc has with my system.
Will "Remove Disk" temporarily dis-able the current TM drive as a TM drive?
Or are the implications of "Remove Disk" far more far-reaching than that?
thank you,

Removed disk in Time Machine, now can't reselect to get my old backups back

I accidently clicked Remove Disk in Time Capsule on my MBA. Now when I try to reselect it in Time Machine (using the Time Capsule disk listed) it doesn't find my old backups.
I don't want to start again as there is all my old backups sitting on the Time Capsule taking up space. Any advice to get my backups back?
One thing I have noticed is the icon for the Time Capsule used to be the Wi-Fi 'fan', but now it's got the people holding hands icon instead. Sorry if they have correct names for the icons but that's the best description I can use. I also have no idea if this is important or not.
Thanks.

If you mean the TM Preferences window shows "None," it just hasn't updated the window yet. See #B3 in Time Machine - Troubleshooting

I'm not sure what you mean. Can you post a screenshot?

Undo Remove Disk in Time Machine

Hi,
I used the Remove Drive button in Time Machine. When I go back into Time Machine and hit the Select Backup Disk button the drive I want to use in not listed. I can connect to the drive in Finder so connectivity is not the issue. I cannot find a solution to this problem. Any suggestion welcome.
Thanks

So you removed a drive from TM, which you were previously using as a TM backup, and then you tried to select it again?
And you did nothing to the drive in between?
TM will only recognise disks formatted as HFS Extended. You didn't reformat the disk?

First Imac in the post. What size hard disk for Time Machine

I have a 500GB hard disk in my new imac (Which I dont have yet)
What size drive should I get to backup my system.

Peggy's answer is essentially correct. OTOH, if after moving into your new computer you are using only 40GB of that huge drive, it would silly to get a 1GB drive, at least until you've found a way to fill up more of the drive....and you will eventually. So to amend Peggy's answer, look at how much drive space you are currently using. If you own a digital camera figure you could easily fill 1GB a year per child. Music and/or Video? Estimate how much you've added in the last year and use that as a rough bench mark. Add another 5GB and add all that together to see how much of your drive you'll have filled by this time next year. Use that to gauge how big your external TM drive should be, based on the 2 to 3 times bigger figure.

I have backed up my disk using Time Machine. Now I want to delete the backed-up files from my hard drive. But when I do and reconnect the external hard drive, the files are also deleted on that. What do I do?

I have backed up my disk using Time Machine. I then deleted the back-up files from my MacBook hard drive.
I then reconnected my external hard drive and find the files I deleted from my hard drive are also deleted from
my external hard drive. Can someone tell my what what happened? I'm confused.

Hello,
Time Machine is not a good way to do that, when it eventually needs more room it deletes old Backups to make room.
If you really want to keep Files but remove them from the Internal Drive, then I'd get another external drive to copy or clone them to that is not used for TM.

Remove disk from backup disks in Time Machine, old backups no longer accessible

I accidentally removed a disk from my backup disks in Time Machine. It said it wouldn't delete any backups, but after reconnecting it, I cannot access any previous backups through the Time Machine interface and it says "Latest Backup: None". The data is still visible on the drive.
What can I do? I really need these backups.

See Pondini's TM FAQs for starters.

I have a 2013 macpro I upgraded to yosemite. Now I find time machine does not work, nor my old back up using a click free wireless back up. What is the status of time machine and yosemite?

What is the status of time machine not working with yosemite?
I upgraded mu mac pro to yosemite and since have found time machine does not work.
Also, my old backup via a clikfree wireless backup does not work any longer.
Is anyone working on this issue?
Is there anyway I can backup my information today and until time machine &
yosemite get fixed?

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the word "Starting" (without the quotes.) You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard."
Each message in the log begins with the date and time when it was entered. Note the timestamp of the last "Starting" message that corresponds to the beginning of an an abnormal backup. Now
CLEAR THE WORD "Starting" FROM THE TEXT FIELD
so that all messages are showing, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ If all you see are messages that contain the word "Starting," you didn't clear the text field.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. Don't post more than is requested.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.

How to limit the amount of disk space Time Machine will use?

On Yosemite, how do you limit the amount of disk space Time Machine will use?
I'm using a Seagate Goflex Home 2tb drive connected to my router as a Time Machine backup drive. I use this for three things 1)Time Machine 2) an occasional backup of windows document subdirectory 3) backup of music and photos for long term storage. Doing something like re-partioning the drive is not an option. I'll just go buy another drive for time machine's sole use. In addition, using software from Seagate is not an option. I don't want to use their software for different reasons (mainly the GoFlex home is really designed as a "media server" which I don't use. I, of course, use iTunes. ) On the Mac, I'm only using about 250GB total but time machine is rapidly using up space.
Apparently using a terminal command like below, used to work, but no longer works under Yosemite.
For a limit of 100gb the number below would be 100 x 1024
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 102400
To remove the limit, use the following command:
sudo defaults delete /Library/Preferences/com.apple.TimeMachine MaxSize
Now, I'm not too familiar with terminal and I'm not about ready to issue a command without knowing exactly what it is going to do.
Is there an easier "switch" someplace or an app that does this?
If I don't limit the size, at some point there will not be any space left for windows backups and additional photo and music files.

Hmm- added "sudo" and there was no error reported:
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize xxxxxx
I guess we'll see.

Recently my MacBookPro locked up on startup. Could not get past a certain point of progress bar. I had upgraded to Yosemite few weeks back, with no issues. I ended up doing a Recovery with Time Machine and I got all my apps, photos, documents, etc. back okay --- except I got error messages that my "registration for Photoshop (I use CS4 Extended) and Photo Mechanic are no longer working". I worked on Photoshop first, and tried (several times) to fix it with their online help suggestions. Nothing worked.
Is there a simpler way to "get my licenses/registrations back"??? I am also going to contact Camera Bits about the Photo Mechanic issues. Thanks

Same problem and for months now. I haven't been able to find a solution, but I suspect that's because I don't know exactly what's wrong.

What does red disk name in Disk Utility mean?

I've got a second HDD installed and noticed that Disk Utility displays its name in red instead of the usual black and partitions are not visible underneath. It's currently going through the process of encryption. What does the disk name in red mean?

Since my last post I rebooted and I no longer have any device in red text in Disk Utility. But what I have now looks strange too.
I created two partitions, called "Time Machine" and "HDD", which I subsequently encrypted. I can no longer see the physical disk in Disk Utility. The partitions I created appear as root devices, with what looks to be their respective encrypted logical drives inside each bearing the same name as the root device.
Here's the output from the command you asked for:

How large should a disk for time machine be vs the hard disk

Can anyone tell me how large a disk for time machine be vs the size of the hard disk?

I usually say 2x or more but your milage may vary on that based on how much your hard drive is actually used, what sort of data (how large the files are) you typically handle and how far back you want your TM backup to go.

Restore one hard disk from Time Machine backup

Is it possible to restore only one disk from Time machine backup? I have a SSD with OSX 10.8.5 on it while user folders are on a separate 4TB hard drive. I also have a Time Machine volume for backups. Yesterday the user drive failed beyond repair, but fortunatly I do have a recent backup. When I tried to resotre following insructions provided in the Time Machine manual, it does not give me an option to resore a specific disk from the backup, and tries to resotre only the System disk backup, in this case the SSD. Is there a way to restore a disk on which no system is installed?

HT201250 Is it possible to use Dropbox or Microsoft OneDrive as the backup disk for time machine?

I have a MacBook Pro for which I have not set up Time Machine. I have a Dropbox account and a Microsoft OneDrive account, each with plenty of space to serve as backups. Is it possible to use either of these as THE backup disk for Time Machine? It doesn't appear intuitive from Time Machine on my MBP.
Thank you.

No. Time Machine does not work with "cloud" drives.

Restoring disk from Time Machine

Hello!
I wiped my disk clean, rebooted using Snow Leopard DVD as a start up disk, and then attempted to restore my disk from my Time Machine backup. Everything seemed to flow just fine... UNTIL the "Transferring Information" window displayed "Transferring your Applications folder...". The blue progress bar has been stuck in the same place for 15 HOURS!!!!! The status still reads "Transferring your Applications folder...". Any insights into HOW I CAN MOVE FROM WHERE I AM TO SUCCESSFULLY RESTORING MY DISK FROM TIME MACHINE, IN A TIME-EFFECTIVE MANNER?
Oh man, I know someone out there can help! I really appreciate anything you can offer in advance! Thank you!
All the best,

Did Disk Utility find any errors on your TM drive?
No errors.
"*The Mac OS X installation couldn't be completed.* / If you continue having a problem installing Mac OS X, the installation log may help you diagnose the problem. To save the log, click Save Log. / To start installing Mac OS X again, click Restart. / To start up your computer using a different disc, choose Startup Disk from the Utilities menu."
There is also a window that is titled "Installer log" will 248 lines that I do not know how to read. Many have phrases like "ReportCrash [179]".
So it didn't get as far as it did the first time? You may have a bad or damaged SL disc, or a problem reading it. See if you can clean the disc.
No it didn't. I tried to clean the disc. I have restarted, and retried, four times now, and continue to get the same message.
If you're anywhere near an Apple Store or Authorized Apple repair location, make an appointment and take your Mac, the disc, and your TM drive. See if they have another disc they'll let you use to see if you can get any farther.
Is this a Genius Bar appointment you're referring to?
One line, early on in the report, that jumped out to me, is "You can't save the file 'Autosave Information' because the volume 'Mac OS X Install DVD' is read only."
Yes, that is a bit irritating, isn't it? I don't know what good it is.
Well, I guess we all did our best. If there's anyone out there with any new insights, I'd love to hear 'em!!!
Again, big thanks to everyone!!!

Can two macs use same disk for Time Machine backup with Airport Extreme?

Hi
I use a Western Digital disk as a wireless Time Machine backup connected to the USB port on my Airport Extreme and it works great. My question is: can my girlfriend use that same disk for Time Machine backup from HER computer too? (I don't mind formatting the disk if needed.)
If she can't, is it then possible to connect a USB hub and have two disks hooked up to the Airport Extreme?
Thanks for helping. I am constantly in awe of all the help people like you give people like me. Thanks!!!

I've gone through the manual setup and the assisted setup and can't seem to get my MacBook to use the Time Machine. Any thoughts or help would be greatly appreciated.
Well, as the Jolly Giant points out....+this type of configuration is not supported by Apple+, so it's difficult, if not impossible, to provide a fix for something that Apple says that you cannot do. Reference these Apple Support documents regarding this topic:
http://support.apple.com/kb/HT2038
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
Your situation is not unlike other users who try this and find that one computer may backup...(usually for a limited time before corruption issues start to creep in)...but another computer cannot backup. Count me as one of those users who thought that because things seemed to work that I had somehow "beat the system".
I started getting the corruption error messages after 4-5 weeks of successful backups, so I figured that it did not make sense to continue to try to get a second computer to backup (yes, I too could not setup a second Mac to backup).
Sorry, I could not get a second machine to backup, so can't tell you how to accomplish that goal. If you want to continue to try backing up this way, you might want to also think about a second backup strategy...just in case backups become corrupted on the WD drive.
Maybe if Apple says you cannot do this, they just may be right?
