Changing disk for Time Machine.

Can I just move the existing Time Machine files from the old to the new drive and then assign the new drive as the one I want to use for Time Machine?
I just want to make sure I have the old History also on the new drive.
Thanks

What's the best process to create a bootable backup?
Is there a system tool that will create one or is there a commercial program that is recommended?

Changed disk for Time Machine -- delete old backup folder?

I got a bigger external drive for backups so I can use the smaller drive for data. I changed disk for TM in System Prefs, and all seems to be well; it's backing up to the new drive. Can I delete the previous TM backup folder on the smaller drive? Or does the new backup location need it for some kind of reference?
Thanks!

If you change TM destinations, it will restart from the beginning (or, resume if a previous backup was started on that volume in the past for the computer in question). In other words, you are safe to delete the old backup.

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?

I need to configure a new hard disk as backup disk for time machine. The set up program is running and it says it will take 9 days to backup about 56 GB. Is it normal ?

5 hours to do 6 GB of transfer is NOT normal, even for USB 2.0 so there's something wrong here. I'd say cancel it, wipe the drive and then test the integrity of the drive. Do some file transfers over to and see if it's behaving normally. It could be a bad USB cable, it could be a bad drive or bad enclosure. As it's new, I suspect you haven't really put it through its paces yet and it's important to do that first before commissioning it to serve as your "reliable backup."

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.

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.

If I choose a hard drive ask my backup disk for time machine, will it clear out the data that was previously stored in my hard drive?

Hello edjhsu,
Unless the drive is in a format that isn't compatible with Time Machine, the files will not be overrwitten. However it is typically a better idea to keep your files and your backup separate, especially since files on the Time Machine drive will not be backed up by Time Machine.

How to turn off the 'Use disk for Time Machine?' warning

I have Time Machine set to OFF.
I use cloning software instead; "SuperDuper" with a "Voyager Q" unit attached via FW 800
I rotate my external backups HDs using 2 x 3.5" HDs.
How do I get rid of the annoying message; ‘Use disk for Time Machine?’ each time I attach an external HD?
I have tried the solution at;
http://www.macworld.com/article/133175/2008/04/105notmdrive.html
but doesn't work for me.
Mind you, the article was written for 10.5 and I was hoping the same solution would apply to 10.6.
Anyone have an answer?
Many thanks in advance,
Michael.

Think I just found the answer to my own question.
External drive has to be mounted on the desktop BEFORE the following command is run.
defaults write com.apple.TimeMachine DoNotOfferNewDisksForBackup -bool YES
this assumes you've setup TM
Now I don't see that annoying message.

Don't, Time Machine knows nothing about Windows, and vice versa.

Changed Hard Disk for Time Machine

I have a question, I've searched and can't find the answer (maybe I'm just not good at searching).
I ran out of room on my external HD for time machine backups, so I added another external HD and changed the time machine location to the new HD. I did not copy any backup files to the new HD, I figured that I'd just keep the old ones on the old HD and start from scratch.
I am using an old iMac G5 that has one (yes, one) USB2.0 port, the other USB ports are the old, slow ones. I have the new HD plugged into the USB2.0 port and the old HD plugged into one of the other ones.
Then I selected "back up now," and it's been backing up for more than 12 hours and it's only about 1/3 of the way done according to the progress report (37.4 GB of 96.9 GB).
Question -- does time machine automatically copy my old back up from the old HD to the new HD? That's the only thing that I can think of that would make this back up so slow. It shouldn't take 12 hours to back up 37 GB, right?

Thanks. I think I need to just wait until it's done and then check things out. I let it run all day while I was at work, and it's another 1/3 of the way to the end. I don't want to stop it and then find out that I just need to let it run its course.
Here is the backup log from the time machine widget:

External hard disk for Time Machine

I'm considering baking up my iMac. I have a Lacie external hard disk with a Master Boot Record partition type. On it, there are already some data files from both Windows and Mac machines.
I understand that, for Time Machine to work, the partition type needs to be changed to GUID (for Intel based Mac). Obviously, I will need to copy these data files to somewhere, then use Disk Utility to change the partition type, partition the hard disk (one partition to be used for Time Machine back-up).
My question is, will it be safe to copy the data files (previously from Windows and Mac machines) back to another partition of the hard disk which will then has a GUID partition type? Will the files (including those from Windows machines) be usable?

You're slightly mixing terminology.
The *+Partition Map Scheme+* applies to the whole disk, whether it has one or multiple partitions. That's what needs to be GUID or +Apple Partition Map+.
The Format applies to each partition, and may be different for each one. Your TM partition needs to be +Mac OS Extended (Journaled),+ the other one can be +MS-DOS (FAT)+ for use with Windoze.
You can copy those files anywhere temporarily, while re-formattng the disk. It doesn't have to be a separate partition. It could even be CDs/DVDs. As long as you can copy and read back, it doesn't matter. If you put them on your boot drive, Windoze won't be able to read them while they're there, but once you get them back on a +MS-DOS (FAT)+ partition, it will.
See the instructions in item #5 of the Frequently Asked Questions *User Tip* at the top of this forum.
We usually recommend putting the Time Machine partition first (at the top of the diagram that Disk Utility will show you), so you can more easily expand or contract it later on, if you need to.

Anyone find a way to use an airport disk for Time Machine?

Apple says it is not possible ( http://docs.info.apple.com/article.html?artnum=306833 ). Yet I have seen some posts of people who claim they are doing it. How?

Here's the workaround that has been posted ...
(NOTE: Caution!!! There is a reason Apple did not include Air Disk support for Time Machine in the current release of Leopard. I would strongly discourage implementing any workarounds, especially if the data you are backing up is critical to you. However, if you're just curious to see if it is possible, then proceed with caution.)
Here's a workaround for the Airport disk problem that may or may not work for you:
1) disconnect airport disk and plug into computer as a USB drive directly.
2) Set up time machine to use this volume.
3) In terminal cd to volume "cd /Volume/HDD"
4) In terminal "touch .com.apple.timemachine.supported" this will create an invisible file.
5) In terminal "sudo chown root:admin .com.apple.timemachine.supported"
6) In terminal "sudo chmod 1775 .com.apple.timemachine.supported"
7) In terminal "ls -l -a" the .com.apple.timemachine.supported file should be -rwxrwxr-t
8) eject disk, unplug from mac, plug into Airport.
9) mount at mac using connect to server in finder (command k) and afp://airportname.local./HDname
10) see if time machine now sees the drive and tries to use it.

Proven external disk for Time Machine backups?

I'm looking for a good, reasonably priced, external disk to temporarily use for Time Machine backups. My 10.9.4 install is messed up and Time Machine no longer works with my ReadyNAS NV+ system. I want to use the disk to backup my MBP and reinstall the OS. Can someone please suggest a proven external disk (2TB+) with a USB 2.0 (or Ethernet) interface?
Thanks,
Ira

Hello all,
I decided to give my 2007 MBP one last upgrade with a new 1TB internal disk that I will install with 10.9.4 from scratch and will (slowly) migrate all my digital hoarding over to it. I've been using the same OWC FW800/USB enclosure since upgrading the original 160GB disk way back when. If TM still doesn't work with the new install (which will narrow down the TM issue to the ReadyNAS NV+), then I will put the current 750GB disk into the enclosure, flash it, and retry TM.
For the record, I chose the HGST Travelstar 2.5-Inch 1TB 7200RPM SATA 6GB/s 32MB Cache internal disk. It was just $75 from Amazon and I used Amazon Points to pay for half of it.
Regards,
Ira

Using 1 disk for time machine and to back up and windows machine

ok so my parents need to back up their machines, my mother on a mac and my dad on a pc (has to use it for work). we have a single disk drive from OWC and im trying to figure out if i can partition it so my mom can use TM and my dad can still back up his machine on it?
if i partition it on mac both the partitions get in the journaled format, and if i leave free space on the drive it doesnt show up on mac (didnt try to see if it shows up on my dads pc)
how should i go about doing this or will it not work?
-matt

Some more info would be helpful. Depending on the Mac your mom has it should be partitioned to APM (PPC) or GUID (Intel) although this has been called into question. It should not be MBR.
The external HDD needs to be plugged into the Mac for Time Machine to work. For Time Machine, that partition needs to be formatted HFS+ (Mac OS Extended - Journaled). The PC partition may not matter as the PC should treat that partition as a network share. However, if your intent is to occasionally plug that external directly into the PC, you need to format that partition FAT/FAT32. The Mac can read and write FAT/FAT32, but it cannot write NTFS (without a paid third party app), hence why I didn't recommend that format. Leave lots of room for the TM backup (2-3 X the Mac's content) as that will gradually grow in size.
