OS X :: How To Go About Backup / Mirror External HD
Sep 29, 2010
I just did a zero delete on my computer and only have CS5 master suite and Lightroom on my computer now (MacBook Pro 2010). I have 2 external harddrives I'm using. Both are 1TB. I have the Master drive with everything on it, and I want to use the 2nd drive to keep an updated copy of everything. Then I have a 3rd Hard drive, that I want to backup the 2nd backup and keep that off site. What is the best way to go about this?

Alright, so this is what I have and what I want to do... What is the best and easiest way to get this done...
I have two 1TB WD Blacks... One I want to use to store all my videos... The other I want to use to backup the first... What are my options? The stuff on this drive rarely changes, but there are times where I will burn several DVDs at a time to the drive... I do this in order to play them wirelessly through my AppleTV...
My main drive is backed up using the TimeCapsule.

At this point I wish I just got a MacPro instead, this wouldn't be a question. I have a new 17"uMBP, bought specifically to take advantage of eSATA through the expresscard slot. I do photography and video work. I bought the best possible card, the Sonnet Tempo dual eSATA, to offer highest transfer speed and because it's the newest technology. To accommodate my media I bought a OWC Mercury Elite Al-Pro 2TB RAID 0. It's great. I wish I got the Qx2 RAID 5 but it's a little pricey and expensive to upgrade, but at least it has redundancy. I need to have a reliable backup solution. Drobo is expandable but I've seen so many poor reviews. I could buy another Al-Pro 2TB RAID 0 and connect them both and do a software RAID 1 with them. Or I could buy a cheap 2TB eSATA external and do daily backups. I could also get a dock and fill up drives as needed. Is there really an advantage to mirroring other than if my drive fails in the middle of a job? Wouldn't the software RAID needlessly slow down my system? Even if I did get the Qx2 RAID 5 it is bad to rely on such a system by itself to both store and backup my media or is it in itself a very reliable solution?

Upon booting the machine, the LCD display flashes a proper view of the login screen for about 1 second
but then goes dark. When an external monitor is attached the external monitor works perfectly fine -- the
only trouble being that the external monitor is not currently set to "mirror" so it is impossible to log in and access the machine. The IT dept at the institute has a monopoly on repair of computers and so the quick answer -- take it to Apple is not all that easy. Is there a way to:
1) set the iMac to mirror display upon booting up by some clever key combination?
2) set the machine to mirror by remote access and command line methods?
3) mirror by changing something using target mode?
4) or the obvious...somehow login using the real estate provided by the external monitor.
Also has anyone seen this problem with iMac displays? An Intel iMac I think 2.16 Intel Core 2 Duo processor running Tiger.

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?

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.

What backup solutions are available for backing up two drives on to one backup drive without causing any confusion?
My setup consists of:
- Powerbook (80 GB)
- external Firewire drive (160 GB)
- external Firewire drive (500 GB) for backup
I'm running MacOS 10.4.11, so please don't suggest Time Machine.

I have 500GB LAcie USB Hadrive, which i currently have partitioned into 200GB for Timemachine, and 300GB which i use to drag and drop files/folders directly from finder.Is there anyway for me to partition the 300GB so i can use this HD to backup some of my bootcamp files.If i can, what format do i partition in. Can i just partition the 300GB now or do i need to reformat the HD and add 3 partitions from the start. Also is xp good at picking up and syncing HDs, esp for drag and drop stuff. Im so used to mac, i assume xp will make my life difficult.

I'm going to install Snow Leopard "currently running Leopard 10.5.8" and I was hoping to put it on my 1.5 TB external HD, that way I don't need to burn it to a CD since that seems like a bit more work since I already have a external HD lying around. So that part seems straight forward enough to me, but then I have the problem of where/how do I backup my mac, I was going to back it up to my external "using Carbon Copy Cloner" but I only have one. So would it be safe to backup my mac to this external and also put the new snow leopard OSX. I mean is there any reason this wouldn't be possible or am I putting all my computers information at risk by doing this? Also I already formatted this External Hardrive to Mac OS X extended journaled.

I am thinking about buying a HD for a full system backup and all files. I am worried about getting such a big HD and having it fail, thus loosing years of data. Is there any redundancy in a 1TB drive does partitioning help? What if the entire drive fails or are there multiple drives in those external hd? I need a reliable backup system for music, photos of child, that will last years. I want to be able to use the HD with both formats, pc and mac...what should I format with or is that a good idea?

Formatting my HD and freshly installing mac OS X, I dragged final cut into my HD and even ran the app from there, does that mean I'm good to go or is it still using files in my internal HD and would not work if completely deleted from the mac internal drive?

i as planning to sell my macbook in the near future and i wanted to back up everything to my external hard drive. I heard of offsite backup but i didn't plan on doing it yet. Anyways i used time machine to make my external hard drive to be my backup disk. First i had to take everything off it (80GBs worth of music, movies and documents) and i put it on the desktop cuz Time Machine said something about incompatibility and i had to erase my external drive first. I then backed up at least 120GB of content altogether to the external hard drive. I checked my external drive and found out the stuff i took out and put on the desktop was NOT backed up. So i deleted the backup and put the 80GB of movies, music, etc stuff in a folder in my computer.
However i can't back up to my external drive anymore. It says it only has 61.28GB of memory left. I'm wondering why is that if i deleted the backup already! I then tried to take the backup out of the trash and put it back in the external drive and it won't go in because there is only 62.28GB of memory. I don't see any partition of any sort on my external drive, no folders, files or anything yet it has magically lost 190GB of free storage.

Looking for advice for setting up my 1.5 TB external backup drive. I think I would like to partition it into 2 drives one 500gb for Carbon Copy Cloner (or Super Duper) and the second 1 TB for Time Machine. The drive is a WD 1.5 TB My book and it came FAT32. Should I re-format this to Mac OS Extended (Journaled) or leave it as it is for the purposes of backing up? I really don't think that I have any files larger than the 4gb although I could have some ripped DVD's before Handbrake sizing down to iPhone size. What about the files that came with the external drive, are the worth installing or just go with the popular backup choices? Oh please let me ask this question as well, what cable connection to the my iMac is recommended? I was wanting to use Firewire but they only provided a 400 to 400 cable and I think I need 800 to 400.

I want to be able to boot from my external drive but I am running into difficulty getting it set up right. I have an intel MacPro running 10.4.11 I have a 500GB LaCie d2 HD QUADRA external firewire drive. It came loaded with Retrospect Express which I am not very happy with. I understand that the hard drive has to be formatted Mac OS Extended Journaled and the Partition Scheme has to be GUID.
My MacPro is partitioned for both Mac OS and Windows XP using Boot Camp. When I first tried to back up my hard drive using Retrospect I backed up the Mac partition first and then tried to back up the Windows XP partition next. When I tried this the Windows XP volume erased the Mac OS volume on the external hard drive. I found the only way I could backup both volumes was to make 2 folders in Retrospect and backup the Mac into one and the Windows into the other one. With this setup I couldn't boot from my hard drive. I contacted Retrospect but they weren't much help .. LaCie couldn't give me any help either except to say that I couldn't boot from there hard drive. I feel that I should be able to boot from the hard drive with the right software but I've hit a brick wall. I'm thinking about trying some other backup software like Super Duper but didn't want to start a long tedious process if erasing etc. until I got a second opinion on whether it's the right way to go.

This is proving a bit a bit of a puzzle to me. I have a 1TB External LaCie hard drive connected directly to my iMac via USB. It has two partitions, both empty. I set the back-up going and it works for a while and then I get:"Time Machine could not complete the backup. The backup disk may have been ejected or disconnected from your computer." Â
I've amended the Energy Saver settings in the system preferences to keep the machine on given the length of time the first update is going to take, but this doesn't seem to make any difference - and I'm not even touching it! I promise! Then the drive disappears from the disk utility. I then have to turn it off and then on again to get it back. I have the TM widget and this is what it has to say:Â
Starting standard backup
Backing up to: /Volumes/Time Machine backup 70/Backups.backupdb
Ownership is disabled on the backup destination volume. Enabling.
Backup content size: 196.7 GB excluded items size: 1.7 GB for volume Macintosh HD
233.92 GB required (including padding), 465.34 GB available

Is it possible to set up a backup between two external drives?

My Macbook running 10.6.8 recently died.My backup is on Time Machine and is on an external drive. I do plan on getting a new Mabook Pro with core i5 running 10.9. How do I transition my information from my back up to the new laptop smoothly. I realize I will lose some of my programs that were not 64 bit.

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.

Is it possible? I am seeking a solution for my household computing needs. We have a laptop (Mac) and a desktop (Dell). I would like to have one external drive to backup both the laptop and PC and also for storage for both. Is this possible? Would it be a four way partition? The only thing I would ever see a need to cross between partitions would be music from our individual itunes libraries.

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.

OK, I read about formatting Fat 32 to transfer files. I will try it tomorrow. My other question has to do with using this for backup. it is a 750 hard drive and I was wondering if I should do anything special if I want to use it for both Timeline and video storage separate from timeline.

So right now I have 2 external hard drives, a 2TB MyBook Mirror edition, set at RAID 0 so its a full 2TB, and a 1TB MyBook Home Edition. I also have three LaCie 1TB drives to back up the MyBook drives.
How I back up is basically copy the contents over to the backups once a month. The problem is, using USB (my only option) takes about 24 hours per TB. Backing up 3 days a month? Not fun.
Can Time Machine do this better? I still have Tiger, so can't test it yet but it seems tedious to do things my way. I would rather be able to plug them in and sync every few weeks and not have to replace every file, just the ones that changed or were added. Can this be done?
I don't keep the drives connected 24/7 so it would have to be manual, and also can Time Machine back up a 2TB drive to 2 1TB drives? The are stuck in enclosures so i have to connect the 2 separately through USB, can't use RAID.
If Time Machine is not the answer, is there some third party program the would not require me to re-copy every file? It would be great if I could save some time doing this.

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.
