Can I backup the contents of an external drive to a network location using Time Machine?

I have just installed a Lacie Thunderbolt external drive as I want the speed to access large volumes of photographs. If I configure it as RAID 0 I will need to back up the data on that drive. I have a NAS drive which I already use for Time Machine and which works well. Can Time Machine be configured to include the external drive in the backups to the NAS?

HT3275 How can I backup my computer to a hard drive attached to my router using Time Machine?

Time Machine does not list my external drive as an option.

Is it a "normal" external HD, connected to the router via a USB or FireWire cable? If so, that's not supported.
If it's a Network drive (NAS), connected to the router via an Ethernet cable, make sure it's compatible with Time Machine for the version of OSX you're running (many aren't, and some that worked on Leopard don't work on Snow Leopard, etc.).
If it is compatible, the maker should provide instructions.

Yes, if they are not exclude then TM backs them up.

If the folder was replaced, it was written over.
Nothing short of forensic data recovery (probably involving taking the drive apart to scan the discs seperately) is going to recover anything (if indeed even that will).

Turn Time Machine OFF temporarily in its preference pane. Leave the window open.
Navigate in the Finder to your backup disk, and then to the folder named "Backups.backupdb" at the top level of the volume. If you back up over a network, you'll first have to mount the disk image file containing your backups by double-clicking it. Descend into the folder until you see the snapshots, which are represented by folders with a name that begins with the date of the snapshot. Find the one you want to restore from. There's a link named "Latest" representing the most recent snapshot. Use that one, if possible. Otherwise, you'll have to remember the date of the snapshot you choose.
Inside the snapshot folder is a folder hierarchy like the one on the source volume. Find one of the items you can't restore and select it. Open the Info dialog for the selected item. In the Sharing & Permissions section, you may see an entry in the access list that shows "Fetching…" in the Name column. If so, click the lock icon in the lower right corner of the dialog and authenticate. Then delete the "Fetching…" item from the access list. Give yourself read access if you don't already have it. Click the gear icon below the list and select Apply to enclosed items from the popup menu.
Now you should be able either to copy the item in the Finder or to restore it in the time-travel view. If you use the time-travel view, be sure to select the snapshot you just modified. If successful, repeat the operation with the other items you were unable to restore. You can select multiple items in the Finder and open a single Info dialog for all of them by pressing the key combination option-command-I.
When you're done, turn TM back ON and close its preference pane.

How can I backup my files to an external drive

how can I backup my files to an external drive?? Can't seem to drag files to the external drive icon

Is the drive formatted for the Mac? Is it a new drive? If so it's not formatted properly:
Drive Preparation
1.Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

I seem to have a corrupted iTunes library. I can't transfer the library to an external drive. The transfer hangs up on a specific tune. Anybody have any ideas. I am running OS 10.6 w/ a 2Ghz Duel core processor.

I have a power pc (g5) computer that I will soon be replacing with a current i5 or i7 mini. How do I transfer the Time Machine files from the internal hard drive on the G5 to an external drive that I will later use with the Mini?

Hi, likely the easiest is to just poll the drive & get something like this...
Get MacScan...

But if you have a good external drive already, just clone it.

HT201250 Can I back up using Time Machine if I have some files already on the ExHD, or do I need a clean ExHD to use Time Machine?

If you try to use a new disk with time machine, it will try to reformat your EXHD. so I would save the items on your EXHD before backing up with time machine or partitioning your EXHD in disk utility

External drive does not show up in Time Machine

I just applied the lastest update today and now my external drive does not show up in Time Machine. It does show up in Finder.

Gracias Sir Kappy, These instructions didn't include Yosemite, but I followed the closest and used Mavericks instructions and the command-R was the key, which I suppose means 'restore?' Nothing is explained as we should all be able to read the programmers minds by now...
Thanks for the help and problem resolved.

If I store files in the TimeCapsule's own HD, will i be able to use time machine to back those files up also? (specifically can i store/run my iPhoto library from TC and then have Time machine also make/include a backup up of the iPhoto library?)

I curretly use my iphoto library from an large external HD (2 tb) and then have time machine back it up to my airport extreme (which has an external HD attached, 500gb ) Long story short... I am running out of storage space on the 'large external hd 2tb'. however, I still have space on the HD (500gb) that is attached to my airport extreme.
My question is,
1. If i move my iphoto library over to the HD attached to my airport extreme, Is there a way for Time Machine to also back this up.
2. same question only applied differentliy = If i purchase a Time Capsule. and store files on its HD. (specifically an iPhoto library) would time machine create backups of this 'locally' stored data on its own TC HD?
TC = time Capsule
HD = hard drive
TM = Time machien

1. If i move my iphoto library over to the HD attached to my airport extreme, Is there a way for Time Machine to also back this up.
Sorry, but no. Time Machine cannot backup from network drives.

Again, sorry, but no. Same reason. The TC's internal HDD is treated as a network drive.

Where did this backup window come from on my desktop. I have always used time machine to backup to an external disc and within the last 2 weeks, this backup window keeps appearing. Where did it come from? Thanks for any help

where did this backup window come from on my desktop. It specifies personal data & settings and tells me when the next backup is scheduled [which I never set up]. I have always used time machine to backup to an external disc and within the last 2 weeks, this backup window keeps appearing. Where did it come from? Thanks for any help

To check your S.M.A.R.T status open disk utility and click on your drive and then click on the info icon.

Can I combine the contents of 2 hard drives in to 1 drive?

I have a new 1TB hard drive that came with applications pre installed. I'd like keep its contents and add the contents from my recent Time Machine backup. Some of the applications are redundant but that's OK with me. I just don't want to lose the contents on either hard drive. My initial hard drive is 256GB and has Mavericks, MS Office 2011, iTunes library and a buch of other apps and files and photos. The new drive is 1TB and is pre loaded with a buch of cool apps. Some are dupes like MS Office 2011 and the typical Macbook apps, iTunes etc. but I want to add the contents from my 256GB drive to the contents of my 1TB drive without losing anything. Do I used "Install from backup disk" in Time Machine?
I backed up the 256GB drive and installed the 1TB drive just waiting to hear how to move the contents ove without wiping the contents of the 1TB out.
Thanks!

I went old school and copied apps, documents and photos from the old drive to the new one.

My macbook pro is slow and gets the loading wheel often - Tried everything, been recommended to start using time machine

Hey, my macbook pro started going slow out of nowhere and gets the loading wheel often, I can't close it without the charger attached otherwise it heats up real bad. I've been told to get a hard drive and back up everything through time machine and then reinstall it but wouldn't that just carry over whatever problem I'm having. I've tried everything that I've found on here like going into disk utility and repairing anything broken, I checked my memory and all that and it was good but I deleted anything unnecessary and put all my music and movies onto an external hard drive.

If you don't already have backups, and you have any data that you want to keep, shut down the computer immediately and don't turn it on again until you have at least one external hard drive to use for backing up. Then see below.
