OS X V10.7 Lion :: TM To Backup From An External SSD Boot Drive?
Mar 25, 2012
I have just installed a 240GB LaCie Little Big Disk Thunderbold SSD as a boot drive for my 2011 iMac (which contains only the 7,200 prm HDD). This has improved read/write speeds dramatically. I have transferred all my data and applications to the external drive in order to see the full benefit of the SSD.
However, I had not considered Time Machine. I thought it would simply be a matter of identifying the external drive and then connecting to the Time Capsule. However, the external drive is not visible in Time Machine set up and I suspect there could be a good reason: that it is not possible.

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it? Â

I have a requirement to encrypt the whole of my boot drive and my mobile Time Machine backup drive that I shall be taking with me on travels. I know I can use FileVault, which will give me an encrypted disk image but I don't like the reliability of sparse images and need the whole of the boot drive to be encrypted. I have tried Truecrypt to encrypt the TM disk, but could not get Time Machine to see it. I've been looking at the Checkpoint Full Disk Encryption product. What I'm trying to find out is if I can encrypt a USB HD with it, but seem to be going round in loops between Checkpoint and resellers.

I just bought a new iomega external drive that I would like to format to be a bootable backup drive. (I'm not sure if I'll use rsync or TimeMachine yet for doing the actual backups).
Should I format it using DiskUtility or TimeMachine? Will TimeMachine create a bootable backup?

My 6-year old MBP17 just lost its logic board. It is now officially a paper weight. Can I boot-up an old Mac Mini from the Time Machine backup created from my laptop (until I purchase a new MBP) ?

I would like to use FileVault to encrypt both my hard drive and time machine back up external drive. Does encryption noticeable slow down the computer.

I used my external hard drive to store important documents off of my previous Mac. None of these documents are on my new Mac. Will I lose these docs if Time Machine backs up to this external hard drive? Will Time Machine save over those docs?

I am trying to get Time Machine to backup my external hard drive. I have the external drive formated as Mac OS Extended (journaled) and I have also removed the drive from the Excluded list.I put some 'test' files on the external drive and told TM to do a backup and when it is finished the only way I can see my external hard drive in TM is if it is connected to the computer. It doesn't seem to be backed up anywhere in TM that I can see.
Info:iMac

I noticed that Time Machine backs up the system ever so often. What happens if I disconnect the external hard drive I'm using as the back up and Time Machine tries to initiate a back up? Will it corrupt anything?

I have a hard drive which is attached to my iMac 24*7. I plan to move all my movies & pictures over to it. Would the Time Machine backup (through a different hard drive) backup my Hard drive?

I just installed a Lacie 1TB P'9231, with the instruction from Apple Tech Support.Â
Still my back ups are failing. I have 625MB available, but it says back up requires 45.3GB of space. What do I do?

I am unable to boot lion from an external drive on both a MacBook Pro mid-2009 and an iMac late 2008. Both have lion installed and I would like to boot from either a FW drive or USB key. I have reformatted both a FW drive and USB and set them to GUID and installed lion but I can only boot them to the Disk Utility App (drive shows up only as 'EFI Boot' when I hold option down).Â
The firmware is up to date and I also reset the PRAM. I am able to boot both computers from an external USB Snow Leopard drive.

Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB). Tested booting from the external disk and it appeared to work correctly. Upgraded to Lion. Several days later attempted to boot from the external disk (by setting the start up disk in the system preferences) but it fails. The system always boots into Lion.
What I've tried: Setting the start up disk through system preferences. Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk. Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).

I had a IBook G4 and an external hard drive as its back up.IBook running something like Snow Lepord, anyway I have a Intel Macbook now with Lion, Ive been told here there is a possible confliction between the AMP external harddrive and lion.I will say a few times I have for limited time been able to access the drive on the newer MacBook, but then Lion (I think) drops it.Â

I have a external HD which has always worked fine under snow leopard. Since upgrading to lion I keep getting the following message The identity of the backup disk has changed since the previous backup.The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk. And after this the drive disappears from the desktop appearing agian only after restart. What can I do do rectify this? Delete and re-intialise the drive?

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

Is there a way to make a backup of your Time Machine backup on a 2nd hard drive? I want to be doubly sure that my data is backed up!Right now I get an error saying that the second hard drive isn't authorized to copy my Time Machine data from the original hard drive I have set up as my Time Machine.

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.

When I eventually upgrade to Snow Leopard, I'd ideally like to do a fresh install (I did Tiger>Leopard as an upgrade install), but I really don't want to have to go through the hassle of reinstalling all my apps afterwards. So, would the following work as a best-of-both-worlds alternative?
1. Update my backup bootable system drive image on my external FW drive
2. Wipe the drive in my MBP and do a fresh install of SL
3. Use the Migration Assistant to automagically copy all my data and apps over from the backup drive as if I was upgrading from an old Mac to a new one
On paper at least, it looks like it ought to "just work"... but I'm wondering whether or not Migration Assistant will work between a Mac and an external drive, or does it have to be between two actual Macs?

Today is a bad day. My old 24" iMac has finally died it looks like and is experiencing the Gray Screen Of Death. I did have an external backup drive using time machine, so I was just going to restore it to my other iMac, but I can't find my boot disk.
I know how to do it with the boot disk, but is there any way to do it without one? I just want to restore the whole thing.

I got the fatal folder with with question mark and grinding sound of the hard drive when starting my 2008 Mac Pro this weekend. After some diagnostics it was obvious the Hard Drive is dead, of course its the main drive that runs the OS and all my apps. I am picking up a new drive today and was wondering the best approach to get it up and running again. Everying it is backed-up on my external drive through Time Machine. Since the drive is dead I can't use a copy cloner to the new drive. Would I install the the hardrive and start the Mac Pro to boot off the Leopard CD, intall that and then try to run the backup from Time Machine?

I have a Western Digital My Book World Edition as a NAS. I also got an external drive (a Western Digital Elements Desktop) to which I want to backup everything from the NAS, and then store it at a different location. My problem is that I can't find any software that does this, everything I find seems to work the other way around (using the NAS as a backup). It would be sweet to have the backup working as automatically and simple as possible, so when I wan't to backup my files the next time, it should only copy the files that have changed or are new. Is there a solution to this problem? I'm using a Macbook Pro with Snow Leopard.
