OS X :: Making Time Machine Work On A Smaller External Drive?
Nov 22, 2009
I'm just about to receive my new Core i7 iMac with a 2Tb Hard Drive and was just wondering whether I could use my old 1Tb Hard Drive for Time Machine Backups.
As far as I know the requirement for a Time Machine Backup Drive is that the drive is at least the same size in terms of capacity as the internal HD of the system you're planning to back up.
I would really like to use my old drive as 2Tb external drives with FireWire 800 are in the 200+ region on Amazon and I'm not sure I would like to spend that much at the moment.

I'm trying to move my Time Machine backup from my Drobo to another disk, so I can reformat my Drobo, then copy back the TM back. The problem is that I don't have a disk that's bigger then the Drobo, so I need to copy it onto a smaller disk before copying it back to the Drobo.I've tried to do this the way that's described all over the web (using Disk Utility), but this always results in the error: Restore Failure, Not enough space on /dev/disk1s2 to restore. I believe this is because everyone is going to a *bigger* disk and I'm trying to go the other way.

Do I have to get the time capsule from apple, or will any external drive suffice?

My MBP has a 320GB harddrive with like 240GB used on it but I only have two 250 GB harddrives so you can see the problem I'm in. I would like to combine into a single virtual drive so that it can accommodate my Time Machine backups.

I checked other post and MROOGLE but didn't find an answer to this question. I am interested in purchasing a Mac Mini, but due to the small size of the internal HDD I would have to have an External HDD attached for iTunes Media. Will Time Machine allow me to backup my internal HDD and External HDD to an additional External HDD...?

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?

I'm going to upgrade my harddrives soon. I use about 300gb of space in my hd, and want to upgrade to a raid-0 (2x1tero) hd configuration... and use my current 500gb drive for my time machine hd. Will that work up until i approach 400-500 gb? Or do i need a 2 tero hd for time machine to work at all? I am not that concerned with having time machine go back too far, i just want an uptodate backup mostly...

I have snow leopard. I have a 1TB time machine set up. After all I just realize that it is too big for what I actually need. I think half of that would be more than enough. I have another 500GB hard drive. I was wondering how can I move my time machine files from a Bigger hard drive to a smaller hard drive.
All discussions, post and forums explain how to do it from smaller to a bigger hard drive using Disk utility. But that did not work for me, there is a error saying that the source is bigger than the destination. Does anybody know how can do this? basically using the apple computer and trying to avoid 3rd party software.PS, The back-up file inside the 1 TB hard drive is much less than 500 GB.

I would like to set up Time Machine with an external HD. Is it worth it? Isn't it supposed to be a seamless backup over a network storage? But if I have to keep plugging my external HD in everytime I would like to backup, will that be good enough? Say, I plug in my external HD every 2 weeks, that would give me a good sufficient Time Machine backup? How long does it take?

I was wondering how time machine would work with an external hard drive.
I need an external drive so that I can make sure that my work is backed up; I believe that Time Machine takes a new backup each time a file is edited?
Anyway; does the external drive have to be partitioned or formatted in any particular way for time machine to function?
I ask because I would like to use my external drive to store games and music (as a backup, not a primary source), but also be able to use it with time machine.
Also, does time machine make a copy of the entire mac drive, or does it just backup specific folders (such as your user areas). If so, can I select these myself?

I have an external 500gb drive plugged into my brand new Time Capsule. The 500gb drive basically stores my entire library of music and my iTunes points to this external drive.
Is it possible to have time machine backup all information on the 500gb drive to the time capsule, so encase the external drive takes a dump, I don't loose my entire music library? Maybe time machine is already doing this, I am not sure.

As my 160N series Linksys router neither has gigabit ports, usb connector or dual band networking, I am looking for a replacement.
When it comes to Apple routers I am looking at 2 options - either the base station with an external USB drive or get a 1TB capsule with the buildt in drive and worries regarding reliability.
What I like about the Time Capsule is that it is neat to have all in one, takes up less space and only has 1 plug to attach, while Iike the idea that I can just connect a bigger drive later on the base station solution.
1. Will the connected USB drive function just like the internal drive in the Time Capsule for Time Machine use?
2. Will everything be transparent to Snow Leopard?
3. In case of both units with an attached USB drive - can I control who actually can see the drive and access it?
4. Do they support this DNLA thing so that e.g . PS3 can access an attached drive??

I've got an external drive that was a Time Machine backup drive. It's at the police station as evidence for something and they will not let me take it back. However, they will let me come down and make a copy of it. I might only have one shot at this so I'm trying to think of the best way to do it successfully and quickly.
Can I just bring another external with me, my Macbook, and then copy the files from the Time Machine backup external drive to the other external drive? If so, what is the facility for doing this quickly? I'm kind of new at Macs and am unsure. I do not have an extra Mac that I can simply use Time Machine to restore to to replace it's contents.

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.

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.
Info:
MacBook Pro, OS X Mavericks (10.9.4)

I was thinking that if i bought an external MOBILE hard drive (un-powered) i could take it with me sometimes when i need it in UNI (in Lectures where there is no power source to plug drive in), but also attach it to the mac and since it is un-powered and mobile time machine will work without needing external power.

Just wondering what experiences other people have had using time machine on a Mac Pro OS 10.5.2 with an external FW400/800 HD.
I am looking at a Lacie D2 Quadra 500GB to back up the standard 320GB internal drive. Never used time machine before, is it any good or is it better to use retrospect or similar. I never use more than 100GB of my main drive as most is backed up to DVD for extra safety. Is it worth getting a SATA card.

I have a MacPro, OS X 10.5.7. I have TM configured to back up to an external 1 TB firewire drive. I use Adobe Lightroom for photography. it provides a checkbox to allow you to backup all photos as you import them from your camera card. Adobe recommends selecting an external drive for these backups. But for some reason, it does not allow me to select the external drive that TM uses.

I have a 320GB internal drive and 1TB (MyBook) external drive. I recently bought a second 1TB external drive (MyVault)to use with Time Machine. I have removed the exclusion of MyBook so that Time Machine backs it up but so far it has refused to do so. It is happily backing up the internal drive. I have looked in the Mac OSX Leopard Missing Manual but still have no clue as to what I am missing. The initial setup (and backup) did not include MyBook until I discovered that I would have to remove it from the exclusions.

I'm looking to get a new drive to use with my MacBook for Time Machine. My current one (something from iomega) clicks like crazy whenever the backup runs, and drives me nuts.
I probably only need 250-320 GB, though I might get a larger one and partition it, using the other half for media, as I'm doing with the Iomega. My top priorities are a) quiet, b) off switch. Any recs?

So I've run into a Mac issue I'm not sure how to handle. I've got a Mac Pro running Leopard. I've got 3 internal Harddrives: 1.) 250 GB (runs my OS and applications), 2.) 500 GB (where I store all my source files for my business), 3.) 750 GB (serves as the backup for Time Machine for all the files on Harddrives 1 and 2.). So I began thinking the other day. What would happen if somehow all 3 harddrives were destroyed (theft, fire, power surge, flood damage, etc.)? I would lose years worth of source files from my business (graphic and web design files mostly).
So I went and bought a 1 TB external drive today. Ideally I would like to put the external drive in another location and bring it out maybe once a week to backup the 3rd harddrive from above (the one being used for Time Machine). Does anyone have any suggestions on how to backup this harddrive...some type of program that essentially acts like Time Machine? I just basically need it to mirror my Time Machine Harddrive. I found a program named Super Duper (http://www.macupdate.com/info.php/id/13803/superduper) not sure if anyone has had experience with it or not. I'm open to any suggestions on how to use the external harddrive to back up my Time Machine harddrive.

I have had Time Machine configured to back up my photos and videos on an external drive. My Time Machine backup is a separate drive attached to my MacBook by FireWire. I have Leopard OS. I have in the past successfully retrieved deleted photos from the Time Machine backups using iPhoto.
Now, unfortunately, the external drive with the photos and videos has developed a problem (possibly power-related) so that my MacBook no longer recognizes that drive. Obviously, this means that iPhoto can't find/open that photo library. Which means that iPhoto can't access the backup via Time Machine. The photos must surely be on the Time Machine backup but I can't figure out any way to retrieve them.

I recently bought a small capacity external hard drive. I don't download and store music, movies, et cetera so I purchased a 250gb Western Digital portable one.
I want to mostly back up my writing (I do a lot), some photos (for convenience, although I don't have many), and files (I have client information on my computer). So for the most part, they are small things.
If my computer was to crash, my worry is mostly that my writing would be lost. My question is, if I use Time Machine, does it automatically back up everything ? Or do I select things? Am I better off dragging and dropping? I am new to this.
Also, I also run Parallels as for one of my jobs, I have to use a Windows based program. I don't do anything else in my Parallels. If I was to lose the info on my computer, and Parallels was backed up, would I have to reinstall it on a new computer? This concerns me as I no longer have my Windows CD that I needed for the initial installation.

I was trying to move all of my movies on to my external hard drive and I copied all of them (took two hours) on there. Then I deleted all but three of them off my computer and emptied the trash. I then look back at my hard drive's files and they aren't there!!! The only thing that was there was the 3 files.
But I also have time machine saved to update my external hard drive. It did and I can see the previous computer times/events/whatever you want to call it. I go to Hard drive>backups.backupdb>My Mac Book Pro>2010-05-04>Macintosh HD>Users>Me>Movies which only shows my iMovie library. I do the same thing but with Music>iTunes>iTunes media>movies to which only one file shows up.
