Can time machine back up a computer with multiply hard drives?

I have a MacPro with three hard drives in it. I have been very impressed with how Time Machine works on another iMac I have and want to try using Time Machine on the MacPro - BUT - I want to know if Time Machine could handle backing up three different hard drives, and, if so, in the unfortunate event that one of those three hard drives fails, could I get Time Machine to restore just that one drive and leave the other two untouched?
Thanks - Rob

Yes, if the drive is large enough.
See #1 and #2 in Time Machine - Frequently Asked Questions.

Also yes. OSX drives are restored per #14 in the FAQ, other drives per #15 and/or #E3 in Time Machine - Troubleshooting

How to stop Time Machine backing up on a specific external hard drive?

I work on a iMac 2.66 Ghz Intel Core 2 Duo, with Mac OS X 10.6.8. I use two external hard drives that are the exact same model, 2 TB WD My Book 1110 Media: one is intended for back-up, the other for storing video editing files. They're both connected through USB 2.0.
I set the "back-up" hard drive as back-up disk for Time Machine, through the Time Machine preferences. Now, everytime I connect the "video" hard drive, Time Machine recognizes it as a back-up disk, and starts backing up on it. I could delete the "Backups.backupdb" file that Time Machine had created by connecting the "video" hard drive to another Mac and moving it to the Trash, but as soon as I reconnect the "video" hard drive to my iMac, Time Machine backs up on it again.
Is there a way to "de-select" a hard drive from Time Machine's list of back-up disks?
Note: I should mention another thing that might indicate a conflict. When both hard drives "back-up" and "video" are connected to my iMac, if I open Final Cut Pro X, I can only see my "back-up" hard drive. To access the files I am working on, I need to eject the "back-up" hard drive, and suddenly the "video" drive appears.
If you have any idea of how to solve this conflict... I am a bit lost.
Thank you!

Welcome to Apple Support Communities.
Give them unique volume names using Disk Utility.
Then set Time Machine back up to that unique volume name.
For example, I regularly use 4 external drives (though they're not all the same model).
The descriptions quickly tell me which drives I have connected to my MacBook when open Finder:
My Time Machine backup volume is named 'Time Machine 1TB'.
My iPhoto backup volume is named 'iPhoto Backup 320GB'
My iTunes backup volume is named 'iTunes Backup 120GB'
and the last is 'Windows 7 Backup 250Gb' but since it's a Windows volume, it is formatted NTFS.
This likely means that you will have to erase and repartition one of your drives to name it.
You MIGHT be able to rename it using Finder, right-clicking on the volume, and selecting Rename (current volume name).
WARNING: I can't be certain of what just renaming it that way could screw up in the way of permissions and file links.
Within Disk Utility, it seems it is absolutely not possible to change a volume name without clicking the Partition tab, and that involves erasing.
Given the choice, I'd probably choose to rename (erase and repartition) the Time Machine drive. A current backup or two on Time Machine, and I'm good. I don't really need to go 'way back' to recover files, because I really don't ever erase anything. I just keep buying bigger drives!
And I still burn the 'absolutely critical, priceless, can't ever be without this stuff' files to DVD or CD at least monthly or quarterly, in case one of my TM or backup drives fails at the same time as my primary hard drive. Call me paranoid, but I worked in Information Technology for many years: Murphy was an optimist!

HT3275 where did my time machine back up go to on new hard drive?

Hi, I recently had hard drive fail on my late 2006 iMac. Had a new hard drive installed. Restored my computer from the most recent time machine back up from my external drive, but can't find restored data on iMac. Any ideas?
Went to the latest backup and hit 'restore' took about 2.5 hours for the data to transfer to new hard drive. I can tell it's chewing up the new hard drive space but the data/profile from my old mac is nowhere to be found on the new hard drive.

It might have created a new user and loaded under that.. new user being the old user. But if you have issues do it again, only this time pick where the backup will go.
http://pondini.org/TM/16.html
The other questions might also be relevant as a new hard disk will make the Mac appear to the TM backup as a new computer.
See 14-18 for restore info.

Having trouble restoring old files from an external Time Machine back-up to a new internal hard drive...HELP!

O.k. So my main hard drive died on my iMac and I had to replace it. I have my old system backed up on my external with Time Machine. How do I access it to get my old files back on my new hard drive? I have read multiple forums and I have yet to find a solution. I was told that when I first turn the computer on and get to the third screen, it would ask me if I wanted to restore from a previous back-up. It did but it didn't show my external until I went through the set-up and got to my home screen. The drive showed then. It also asked to install updates...and I did. So everything is up to date. I have not turned time machine on yet because I'm affraid that if I do, it will erase my old back-up on my external. I tried using the Migration Assistant in Utilities and all I get is the spinning wheel when I tried to get that to work. So now I am here asking for help. I'm not very hopeful that I'm going to be able to get all of my old files back... Any help would be greatly appreciated.

Thank you for the video link. I did it pretty much exactly the way the young man explained. The one thing I didn't do was click "customize" as he does and unclick the multiple language support and he also clicks "rosetta" to support older programs. I wonder if that's the issue? The guys at Macmall told me that I would need to update the o.s. before I restored. I did that originally but have since (as mentioned before) erased the main drive. I noticed that when he does his install, his external drive does not show up on the list in which you want to install the o.s. on... should I unplug my external? I'm just trying to look at ever detail. I know the recovery file is there. The one thing it (the external) did say before I started posting here was "in progress". I'm not sure what that means? I promise I'm not an idiot. I consider myself an above average user. I usually help other that have issues... but I've yet to restore from a Time Machine back-up and I'm looking forward to learning how to do it.... the right way. I appreciate all of the advice. I have some pretty important files on my external back-up. I am really hoping that this is possible. I'm beginning to think the external is where the issue lies. The "in progress" next to the file name concerns me. I know there's a lot of data on the drive because it's nearly half full. So there's stuff there....
Deep breath in...... reeee laaaaaaaxxxx

Time Machine back up made from an external hard drive

Hi...to all
Last week i bought a Macbook. I pluged in my external hard drive Maxtor OneTOuch 4 Plus and it did a time machine backup on the Maxtor OneTOuch 4 Plus. The folder that was generated by the time machine on my external hard drive has the name backups.backupdb.
Then, i decided to return the Macbook and bought a Macbook Pro.
When I pluged the same external hard drive, Maxtor OneTOuch 4 Plus, although I am able to access and open individual files and folders, I am not able to copy neither any nor all the folders from my external hard drive to my new Macbook Pro. Moreover, I am able to access/open the files located in my external hard drive but when try to copy specific files from this drive to my Macbook Pro I get the following error message: Sorry the operation could not be completed because an unexpected error ocurred (Error code -50). Now, here is where it gets interesting: after 2 failed attempts to copy files from my external hard drive to my Macbook Pro desktop and receiving the above error message I am then able to copy the specific file (singular). This would mean that to copy the files and folders in the external hard drive i would need to do it on a one by one basis? If so, it would take forever...
Can someone please kindly help out.
Thanks on advance

Can Time machine back up to two hard drives?

I want to make a Time machine back up to two different external hard drives. I can't use RAID-0 because the size of my external drives is different.

HT201250 Since time machine backed up my computer does that mean I can delete files so I can increase storage space on my hard drive?

Since time machine backed up my computer does that mean I can delete files so I can increase storage space on my hard drive?

NO!
Time Machine is not an Archival Backup. It will keep files for a while, but if it needs the space, it will delete files that no longer exist on the hard drive.
Get a couple external drives and move the files to both of them.

I have just installed a 2TB time capsule on my iMac i7, it see my second 1TB hard drive but the 256 SSD doesn't come up in the list of hard drives I can back up. How can I enable the time machine to see my first SSD 256gb hard drive?

iLife is preinstalled on all the Macs. If you purchased iLife in the App Store or your computer came without DVDs, open App Store > Purchases and download the applications. If your Mac came with discs, insert the Applications DVD and install iLife applications

NicholasLiban -
When you use the Lion restore as described, it does a fresh install on the hard drive that you can select at the beginning of the process. This provides a complete install of the very latest version of Lion, including the recovery partition. The drive that you choose for the installation destination winds up like what you would have on a brand new computer from Apple.

I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?

I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?
What I am ultimately wanting to do is make more room on my computer by backing up all of my files onto the external hard drive and then deleting them off of my computer. However, neededing to be able to retrieve them from the external hard drive later down the road.
From what I have read and am trying to understand, is that I probably shouldn't have used time machine. I need to use the external hard drive like a basic flash drive where I can put things on and get things off without having it automatically update through time machine everytime I connect it to my computer.
Not tech savvy at all and barely understand basics. I need very simple and easy to understand explanations.

BIG BIG MISTAKE ..... youre making a linchpin deathtrap for your data trying to shove everything on a single fragile HD.
Dont suffer the tragedy other people make, buy another or 2 more HD, theyre cheap as dust.
The number of people who have experienced terror by having a single external HD backup is enormous. One failure that WILL HAPPEN, and kaput,......all gone!
Dont do it, its all about redundancy, redundancy, redundancy.
follow here:
Methodology to protect your data. Backups vs. Archives. Long-term data protection
Deleting them off your computer is fine....having only ONE copy is extremely BAD.
The Tragedy that will be, the tragedy that never should be
Always presume correctly that your data is priceless and takes a very long time to create and often is irreplaceable. Always presume accurately that hard drives are extremely cheap, and you have no excuse not to have multiple redundant copies of your data copied on hard drives and squirreled away several places, lockboxes, safes, fireboxes, offsite and otherwise.
Hard drives aren't prone to failure…hard drives are guaranteed to fail (the very same is true of SSD). Hard drives dont die when aged, hard drives die at any age, and peak in death when young and slowly increase in risk as they age.
Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.
Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret.

Can time machine back up an imac and an external hard drive?

I currently back up my imac via time machine but to reduce space on my hard drive I want to move my itunes library onto an external hard drive. If i do this can time machine still back up my imac and the external hard drive with the itunes library on automatically?
Regards

yes, given enough space on the destination drive (your library may grow over time). also, the drive needs to be connected directly to your Mac.
you might want to make sure the drive is not excluded from TM backups by checking in system preferences > time machine > options.
also, as for moving your iTunes library, see this read for tips/instructions.

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.

Can time machine back up on a wireless network

I would like to find a way to back up my Mac other than on an external drive. Besdides Time Capsule, can Time Machine back up onto other wireless networks? Also, is there a preferred, Mac-friendly online backup available (that may or may not use Time Machine)? I was considering using Carbonite.

Time Machine can backup to any device that has Time Machine Extensions.. eg some NAS have this.. or another Mac. Maybe some routers with USB drives.. I have heard of Netgear Mac compatible models.. but never forget.. apple change things around with every OS release and these companies will always be playing catchup.
You may also find it not easy at all to setup Time Machine.. I use a Zyxel NAS single disk model that does support Time Machine.. it has been fine.. but the setup is far more complicated than any TC.
Very few other devices will have TM available .. but if you use a third party software, then they will generally backup to any shared partition or drive in the network.
Buy a second hand TC and modify the power supply.. put in a big hard disk.. you can simply plug it into the existing network.. you will find it hard to get anything cheaper that works as well.. and none that will be as easy to setup.
Fine if you give up on TM.. then whatever external drive the software uses.. no issues.. but TM is designed to only work on HFS+ partition.

Can Time Machine back-up to an external ethernet Harddisk?

Can Time Machine back-up to an external ethernet Harddisk?
I think it is only possible when the external drive is directly attached via USB or FireWire.
I do see the ethernet disk in Finder and have access to it via ethernet, but it does not show up in Time Machine.
What if I connect it to an Airport Extreme ethernet port?
Time Capsule will work, but only with the internal harddisk?
My Ethernet disk is a LaCie Ethernet Mini Disk which supports Mac OS X.
Thanks,
Benny

backups to NAS devices are not officially supported. the only exception is Time Capsule. It also works with an Airport Extreme base Station. There are hacks to enable backups to NAS but you use them at your own risk. see this link

Can Time Machine back up both an iTune and iPhoto Libraries saved on a NAS disk?

Can Time Machine back up both an iTune and iPhoto Libraries saved on a NAS disk, as well as the host drive on a Mac Mini?
I would like to know if Time Machine could back up these Libraries from a NAS and the host/main drive of a Mac Mini onto an 3rd external drive attached by Firewire?
Thanks

no.
time machine cannot backup networked drives.
however, ChronoSync may be able to do what you want.
