OS X V10.7 Lion :: Back Up With Time Machine To A Previously Used Hard Drive?
Feb 24, 2012
I've just replaced an old MacBook Pro with a new one and used Time Machine to get the new MBP set up. All is well and it looks like my new computer is a mirror of the old (tested for a week now). If I turn on Time Machine with the new MBP using the same hardrive as the former, will the files remain and be accessible? Presently, I can only access the old files by going into the hard drive through Finder and even then, most are locked.Â

Time Machine is backing up my internal 1Mac hard drive fine to an external drive ("backup ext drive"). I have another external hard drive attached to the Mac that I would also like to back up to the back-up ext drive. I've looked around on Time Machine as best I can but can't find any place that lists drives to be backed up, so I can tell Time Machine to back it up, also. I have found a list in Time Machine of drives I can back up to. That list shows both external drives. But of course, I want to back this one up, not use it as a back up drive. Should be something simple I'm missing. I've seen a lot in the forum about issues backing up external ard drives via Airport Express (or Extreme), but though I have Airport Express, both external drives (back up ext drive and the one to be backed up) are directly connected to the iMac, so I'm not trying to use Airport for this.

I use Time Machine for backing up my iMac hard drive I am into photography and have a large number of photo files that take up a lot of space. The originals I burn to a DVD but the pictures I put on an external hard drive 1 tb so they are readily accessible. Is there any way I can use Time Machine to automatically back up this hard drive onto another external along with my iMac hard drive, or do I need to store the files in duplicate manually on 2 different external hard drives?

If I have two hard drives in my Mac Pro, can I back them up to one external drive with Time Machine?
If I have a third drive that I DO NOT want to back up with Time Machine, can I specify that I want to back up the first two but not the third?

I had Time Machine making wireless backups from my MacBook to a LaCie hard drive plugged into an Airport Extreme Base Station. It's worked great for at least year. The 10.5.8 upgrade seems to have broken it. It's still not an Apple supported configuration.

1) I have a full external hard drive and would like to transfer all my time machine back-ups to a new larger one. How do I do this?
2) And when I'm ready to transfer all time machine data to my new iMac using external hard drive can I choose all dates so I'm including all pictures videos etc?

I probably have all kinds of misconceptions about Resetting to an earlier time for the computer I have. It's a 2009 macbook, running OS 10.8.5. I got it last week, previous to this machine I have been running a powerbook G4. It does not have a backup with Time Machine either.

Mac Mini running 10.8.5. Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications. TM does back up the internal HD.

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.

Time Machine is not working correctly since installing Lion. I found (from using Adobe Bridge) that there seem to be automatic back ups being made 20 times a day and onto my hard drive! Usually I back up to an external drive specifically for back up using Time Machine. Now time machine takes several hours to back up when I have that disk wired in (with USB) and the Time Machine icon in the Apple menu is always showing that the back up is delayed. Â

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.

I have a 500 GB external drive that uses FireWire. Recently Time Machine started deleting several backups to make room for new ones. It now says the oldest backup is May 4th, 2012. I thought this sounded like a problem. When I looked into the details, my iMac now thinks my hard drive has 400GB instead of 500GB.Â

from there I only need my mail messages and folders.Â
How do I go about getting them on another machine (not the one that did the Time Machine backups)?Â

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 backed up my iMac desktop at work onto an external hard drive. I can see the files, but they are all locked. When I go to open, I receive the following message "The folder (whatever the name is) can't be opened because you don't have permission to see its contents." I understand that the system I want to transfer to is different, but is there -- shouldn't there be an override asking for the password.Â
Since I am the administrator to both systems, I would hope I could see the documents that I created.Â

Since the harddrive of my IMac was full, I added an external harddrive to the system for my photos. I use another external harddrive for time machine back-ups (backing up both the IMac and external harddrive with my iPhoto libraries). Recently the EHD with my photo libraries crashed. I now want to restore it from time machine onto a new external harddrive, but am not quite sure how to do this.

I am backing up my data from my mac book pro for a second time. I plug in my external, and it says it doesn't have enough memory to back up my computer. I have 1 TB hard drive and used about 650 MB for the first back-up. Obviously I don't have enough to back up everything for a second time. I just want to back up the new stuff. When I go to exclude the current external from the new back up, it's grayed out. Do I have to delete the contents of the hard drive and re-back up the entire computer?

I have a question which I am quite unsure. I am shopping for a HDD drive (Western Digital My Book 3 TB) and was told that it cannot be reformatted to be compatible with TIme Machine.
I would like to verify if it is true.

I was trying to set up my Time Machine to an external hard drive. I didn't continue because it asked to "initialize" the hard drive which I had a lot of important things on.
I have another external hard drive I'd like to use but, my Time Machine has this error code of -43. What is this and how can I use my Time Machine on another external hard drive?

Everyone seems to want to back up to a flash drive, but what about someone who is carrying around valuable files to work so he can work on them in various locations (home, lab, school computers etc) and wants to safeguard against possibly losing such a small object or some other file problem. I am missing something extremely obvious here? Time machine settings show my flash drive but does not allow me to include it in my back ups...seems strange.

When I ran TIME MACHINE for the first time, it reformatted my external hard drive. TIME MACHINE then backed up my system. Is it possible for me to store misc other files and what not on the same drive as the TIME MACHINE back up? Also, will these files be accessible from a PC also? I want to make sure I am not going to corrupt anything before trying this.

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.
