Backup to Ext. Hard Drive/Time Machine - Partitions??

I have a MacBook Air that is almost full and I need to back up to an external hard drive. Mainly, I have photos and videos that are taking up the majority of space. I have a Seagate 1TB, and am ready to do this, but cannot decide how many partitions to have. I was told to have two: one for Time Machine and one as a Backup.... Is this a good suggestion? If so, how large should each partition be?
Once I get it all set up will the MacBook Air take over and regularly back up my files? Also, I was told that I could use the same external hard drive to manually back up a pc's files.....??

If you wish to have a permanent storage of the data on your computer, then you cannot use Time Machine for the backup. The question then is what is the purpose of the external drive - storage or backup. It should not be both even if you partition the drive. If the drive should fail or become corrupted and require repartitioning then you have lost both the stored files and your backup.
You should use a separate drive for each purpose. If you need storage now as well as a bootable backup, then you can clone your computer's drive to the external drive for now which will also serve as a backup of all your data:
Drive Partition and Format
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.
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
You can incrementally update this clone using one of several backup utilities:
Suggested Backup Software
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup

Recommendations for 1tb/500gb ext hard drive (Time Machine compatible?)

Getting a Macbook Pro with either 320gb or 500gb internal drive. (If not when I buy it will eventually upgrade to 500gb). New to Macs. Looking for good, reliable(?) ext drive for system backups I guess with Firewire 800 connectivity as the Pro has that. Suggestions?

There are 3 I will endorse with confidence they are:
OWC Mercury Elite Pro Series
OWC Quardra D2 Series
G-Tech G-Drive Series
All have similar feature sets and build quality. Although I have 4 of the Lacie's I wouldn't hesitate to use either OWC or G-Tech either. I would also recommend you read the following article about backup strategies from MacWorld, while I think the author goes a little over the top the point I'm trying to stress is the importance of redundant backups.

Restore iPhotoLibrary specifically from EXTERNAL Hard drive Time Machine back up?

My laptop Photo Library is corrupted somehow. I tried to restore from a prior in Time Machine on laptop and made the mistake of not saying to keep BOTH copies, but after trying for 3 hours of telling me it was doing it through various windows, a little one popped open saying something about permissions and it opened an old iPhotoLibrary from 2 years ago! ... I do have that one now and am copying it off my laptop as fast as I can to FLICKR
cuz APPLE has become a PHOTO sinkhole... (We are talking 20,000 pics folks with scanned in family pics from 100 yrs ago!)
I think I have a good copy on my External Hard Drive Time Machine back up from about 3 weeks ago. How do I use that to Restore from
or should I just wait for this PHOTOS thing to come out?
NEXT Question is there a convenient way to split it into MULTIPLE ones..eg KEEP old stable photos in one or more.
and use another for all the new ones not editted or sorted yet? I do see there is a new Option under iPHOTO/File menu to just switch
libraries but, of course, you cant even see that if your Library wont open!

For TM help post in the forum for your OS - and see https://www.apple.com/support/timemachine/ and http://pondini.org/TM/FAQ.html and http://pondini.org/TM/Troubleshooting.html
Depends on undisclosed information
With the current OS and iPhoto you switch library using the switch library command - with any version you can switch libraries by holding the option key down while you launch iPhoto which brings up the select library window
And generally it is not a smart idea to have multiple iPhoto libraries - it generally has no advantages and makes things much more difficult and complicated and often leads to user errors that cause major problems
If you want to anyway the most convent way to split libraries is to use the paid version of iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -

Time Machine won't backup to ext hard drive?

I keep receiving the error message that Time Machine won't backup to my ext hard drive since it can't create the backup file. Why? Same ext hard drive for over 2 yrs. Using iMac (early 2008) with Mountain Lion.

Is it at least twice the capacity of the original?
Is it formatted with a GUID partition?

Hard drive failure! New hard drive/Time machine backup/iPhone questions

Hello,
I have a 2011 MacBook Pro who's hard drive failed (rather acutely too, I do use disk utility to check it's health regularly) and I bought a replacement to install (SSD!). I have a bunch of questions but have only found partial answers in searches. Maybe it's best to list them:
1. I'd like to do a fresh install of the OS X using OS X Recovery because I'm concerned my Time Machine backup is partly corrupted. I hadn't updated to Mavericks, will I be able to install Mountain Lion? If not: will this be a problem with my backup files?
2. Say the OS X Recovery works, how do I use Time Machine to restore things like my iTunes library/iMessages/email/iPhoto library etc? In other words: just the data I can't get any other way (I hope it's not too corrupted). And/or should I use my iCloud backup on a few of these (iMessages/contacts)?
3. Do I need to set up the new OS X install with the same account names/home disk name etc. for the restored backup files to function?
4. Is this going to f'up iCloud or vice versa?
5. Finally, how do I sync my iPhone to the "new" computer without erasing the iPhone (which had an iOS update since my last backup to Time Machine). Or do I have to restore the iPhone too.
6. How come Apple doesn't have a mobile theme for their website yet?
Any help would be much appreciated,
Matt

Do you still have the original System Reinstall DVD set that came with your Mac?
If you created that Lion external drive you have from YOUR Mac, when Lion was installed on it, and it also contains a Recovery HD partition you can use that to boot to the Recovery HD and reinstall Lion on the new drive. And or Clone that external to the new internal drive you installed.
Right since your Mac came with Snow Leopard you can't use the Online Internet Recovery system to reinstall Lion, as your system didn't originally come with Lion, but you should still be able to boot to it to do diagnosic things like using Disk Utility, going to the Net to get help and even Restoring the system from a Time Machine backup. But you will get an error if you select Reinstall Mac OS X. The firmware update is usually applied with system updates.
If you created a New Time Machine Backup when any of the Download Only version of OS X were installed on your internal drive Time Machine, the system, Copies over the files needed to boot the system from that backup drive. If it was a care over backup from when Snow Leopard was installed is might or might not be bootable. Only way to tell is to connect it and at startup hold down the Option key to get the Boot selection screen, IE The Boot Manager screen, and see if it shows up as a Boot Source. If it does thenn it contains the files needed to get to the Mac OS X Utilities, IE the Recovery HD files.
What you should do is Boot the system from either the Time Machine backup, if it is bootable, or your External that has Lion on it, The Recovery HD if that drive contains a Recovery HD, or your Original Snow Leopard reinstall DVD that came with your Mac and then try to Restore from your Time Machine backup drive.
If that fails to restore your system properly then nyou should reinstall Snow Leopard and the iLife Apps from the Original Discs then upgrade to Mt Lion which will be in the Mac App Store under your Purchases area. Then maybe you can restore your files from that Time Machine backup.

I've had a bunch of issues with my computer (you can look at some of my other questions on these forums) which, to my mind anyway, seemed to be finally given a diagnosis when my HD crashed. It may be paranoia but there have been enough problems that I'd rather do a clean install to be on the safe side.
I have an early 2011, shipped with Snow Leopard.
I was under the impression that Time Machine can't be used as a boot drive and the OS X Recovery is a firmware update (on my computer) or hard wired in (on later computers). I might be wrong. I was planning on using the internet recovery, the HD failed right after I got some password protected files unencrypted and onto an external drive (was that necessary?) but wasn't sure if it's a problem if it installs Mavericks.
So Setup Assistant will configure my accounts the same and I don't need to worry about that? That's a relief.
Thanks for the lengthy response.

External Hard drive/Time Machine backup error message

On a sidenote, I posted a question a week ago about what external hard drive would be compatible with my Macbook, and I so happened to get a WD My Passport Studio hard drive as an unsuspecting gift, so I didn't have to buy one.
Anyways, I started the backup on this hard drive and I had an error message: "Unable to complete backup. An error occurred while copying files to the backup volume." I searched this on the Apple Support Communities and found that I wasn't the only one who had this problem. So, I came upon one discussion that suggested downloading Time Machine Buddy (link:http://pondini.org/TM/A1.html) (link that prompted me to download: http://pondini.org/TM/C3.html). I downloaded it and found out that the error was occurring in my Library folder, specifically in the folder entitled "db" in the "Receipts" folder. There's one file in the "db" folder entitled "a.receiptdb" <----can someone please explain what the heck this is??? Lol. Anyways, I decided to exclude the whole "Receipts" folder from being backed up and now my external hard drive is backing up my files fine. My MAIN question is this: What is wrong with my receipts folder that is causing the error?
P.S. here are the error messages in the Time Machine Buddy log:
Error: (-36) SrcErr:YES Copying /Library/Receipts/db/a.receiptdb to (null)

As you can see, iy is located in the "db" folder. I have no idea what's wrong. Thank you for your time! It is MUCH appreciated.

The connection to 10.6.7 may just be a coincidence. I had a similar problem with a disk and was about to throw it out but decided to try a different USB cable. That fixed the problem and the drive is still in use.
Try a new cable if you have not already done so.

External Hard Drive/Time Machine Questions

The hard drive on my four-year-old-plus MacBook Pro is apparently failing, and I can't afford a new MacBook Pro yet. So I bought an external hard drive, hoping to clone my hard drive and run my computer off the external hard drive if the main drive crashes.
At the moment I can't afford an Apple external hard drive, so I bought a non-Apple model. So I was surprised when it asked if I wanted to use Time Machine to back up my data while I was setting it up. I chose yes, though I'm not even sure if I've set it up correctly.
OK, let me start from square one...
My external hard drive has 1 TB of storage space, and I initially formatted it in one big block - no partitions. If I want to boot off a cloned hard drive, will I have to partition it, so I'm booting off a particular partition?
If I do have to partition it, I understand I can use Apple's Disc Utilities to do the job. Can anyone tell me if there are any special steps or conventions I need to follow? I'd probably create a partition of about 200 GB for my cloned hard drive. (I'm currently using about 120GB on my internal hard drive.)
In fact, I might make two separate 200-GB partitions, cloning my hard drive to one partition, then cloning it to the second partition a few weeks later, just for security.
My first Time Machine backup is scheduled to begin in just half an hour or so. Will it merely copy all my files to the external hard drive, or will it create an operable clone? Approximately how long do you think this initial backup will take, using firewire?
Also, once I get my hard drive cloned, I'm thinking of booting up with the clone and upgrading to Snow Leopard. If everything works fine, then I'll upgrade my main (internal) hard drive to Snow Leopard as well.
Sorry for all the questions. I think I understand the basics; there are just a surprising number of details to figure out.
When I can afford it, I hope to upgrade to a new MacBook Pro 13" or 15" and an iPad, which I'd like to take to work with me.
Thanks for any tips.

yes.
you would need to partition it and use one partition for cloning and the other for TM backups.
i don't recommend such a setup, however. it's like putting all eggs in one basket - if (not when) the external fails, you'd have lost both backups @ the same time !
If I do have to partition it, I understand I can use Apple's Disc Utilities to do the job. Can anyone tell me if there are any special steps or conventions I need to follow?
yes.
you can use the instructions in [this|http://web.me.com/pondini/AppleTips/DU.html] user tip.

the partition for the clone needs to be just a big as your startup disk (e.g. 120 GB). the partition for TM backups, otoh, would ideally be 2-3 times the size of your startup disk.
more information [here_|http://web.me.com/pondini/TimeMachine/1.html].
Will it merely copy all my files to the external hard drive
it will back up everything on your startup disk unless you specifically exclude files from backups.
or will it create an operable clone?
no.
use software such as _*Carbon Copy Cloner*_ to clone your system.
Approximately how long do you think this initial backup will take, using firewire?
the initial backup could take overnight - depending on how much data is to be backed up.
Also, once I get my hard drive cloned, I'm thinking of booting up with the clone and upgrading to Snow Leopard. If everything works fine, then I'll upgrade my main (internal) hard drive to Snow Leopard as well.
yes, that will work just fine. in fact, some users recommend this technique even if the internal drive is not about to fail - better muck up a clone than the regular startup disk.

Saving files on the same hard drive time machine is using

I was wondering how I go about saving files other than backups on the hard drive I purchased. If you can help it would be greatly appreciated. Thank you.

If you haven't started your Time Machine backups yet you can partition your new drive, using one partition for Time Machine and the other for file storage. If you assign partition #1 to Time Machine you can reclaim the space on partition #2 for Time Machine at a later time.
You can follow the directions in this article. for formatting/partitioning a drive for Time Machine but you want to end up with two partitions rather than one. People with PPC Macs should substitute Apple Partition Map for GUID when following the directions.

Remote bootable hard drive & time machine

I am trying to move my old external hard drive (time machine ) to a new one

I have tried to move my old external drive time machine to a new external drive:
1. have formated the new time external hard drive
2. I have unlocked and ignored the drives ownership
3. I have turn of the new hard drive and them tried dragging the file (backups.backupdp) to my new external hard drive
when I do that a message come up that says "this volume has that wrong case sensitivity for a backup"
What does this mean and how do I fix it?
Thanks
Denise

Although the documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. All existing data on the destination volume will be erased. That shouldn't be a problem, because you don't want to mix backup and non-backup data on the same drive anyway. Turn Time Machine OFF in its preference pane while copying the volume.

External hard drive time machine backups not mounting

I have used Seagate 500.11 external hard drive as a backup location for the time machine for over two years. I just got a message that it had not updated in over thirty days. It is not listed on FInder, but it is listed on the disc utility. The Time machine backups are grayed out on the disc utility screen and cannot be mounted, even after the repair and verification tests said that their volumes were ok. What should I do?

Time Machine does not create bootable clones. It does not even create a bootable backup. If that's what you prefer then do not use Time Machine.
If you use Time Machine then you must allocate at least twice as much space for the backups than the capacity of the drive you are backing up. A 2 TB backup drive would be suitable for a 1 TB main drive or smaller.
If you plan to create a bootable backup, then partition the backup drive with one partition the size required for the clone. Then use the other partition for you additional storage neeeds.

AirPort Extreme & USB Hard Drive Time Machine Backups

Hi everyone. I'm a brand spanking new MacBook Pro owner and am looking at ways to backup my machine and to save my films, photos and files on a wireless network that is available to everyone in my home.
I'm the first to admit that I'm not the most computer savvy person but I'm okay with the basics. I've read through a lot of forum sites and the community pages on here and most seem to recommend Synology products. They do seem very good but are a good price too once you've bought the hard drives to go with it. I already own an external hard drive so I thought that maybe the AirPort Extreme would be the ideal choice as I know that it can be connected and files can be saved wirelessly. I did read tonight however that you cant backup your macbook using time capsule which is a little bit annoying.
I have two questions really, firstly is it the case that time machine won't backup to an external hard drive connected to the AirPort Extreme and secondly, how important is it to back up through time machine? I'm what you could describe as a low level user and will only be using it for simple tasks such as watching/saving films, storing and editing photographs, surfing the web and saving the odd pages and numbers document.
Thanks in advance for any help you can offer.
Simon

I have two questions really, firstly is it the case that time machine won't backup to an external hard drive connected to the AirPort Extreme and secondly, how important is it to back up through time machine?
The very latest 802.11ac version of the AirPort Extreme DOES support Time Machine backups to attached external USB HDDs. All other 802.11n models are not supported by Apple for these types of backups. A number of folks have been successful doing so, but most typically post here about data corruption issues.
Time Machine is not the only backup strategy, but it is very convienent. I would recommend that your overall backup strategy includes at least two types of backups: 1) Incremental ... like the ones Time Machine supports, and 2) Disk cloning. The latter is very effective for quickly getting you back up and running if your Mac suffers an internal HDD loss.

Erase Hard Drive;Time Machine Backup

I recently discovered that I have some bad directories in my main hard drive which is causing some performance deficits on my computer. I always use an external hard drive exclusively for Time Machine, and it backs up several times a day. If I wipe my hard drive, will I be able to select my Time Machine drive and restore everything I had prior to erasing the disk? In my Time Machine preferences, I have not excluded the backup of any kind of file. Will my computer (all settings, preferences, etc.) be exactly as it was before the disk erase if I back up from my Time Machine drive? I just want to make sure that I don't lose anything? Any help would be greatly appreciated.
-P.

Hey there,
Yes, if you backed up everything and restore everything, your computer should seem as exactly as it was. More on restoring from Time Machine can be found in the link below. Hope this helps.

External Hard Drive/Time Machine 101

I was using a 500 GB external hard drive with my MacBook Pro. I cloned my hard drive to the external hard drive, then used the remaining space to store videos, images, etc. When my aging MacBook Pro finally crashed, I was able to boot up the cloned drive and work with it.
I now have a new MacBook Pro with a bigger hard drive (750 GB, I think). I also bought a 2 terabyte external hard drive (My Book for Mac), planning on doing the same thing - cloning my hard drive, then using the remaining free space to store extra stuff.
However, I discovered that my new external hard drive is much more sophisticated than the last one. It gives me the option of using Time Machine or automatically copying all my files to the external drive. So I'd like to go back to square one, find out what my options are and figure out the best strategy.
First, if I use Time Machine to back up my files, will they effectively create a clone that I can boot up? (I've never used Time Machine before.) If so, then I'm thinking I might not partition my new hard drive. Instead, I would just let Time Machine back up my files. If it creates a 1,200 GB clone, then I could copy videos and images to the remaining 800 GB of hard drive space.
If Time Machine doesn't create a bootable clone, then I'll probably just do what I've been doing - use a program like Carbon Copy Cloner to clone my hard drive, then use the remaining space to store graphics. However, I wonder if I could still get by without partitioning my new hard drive. With two terabytes, it seems like it might be more efficient to just leave it unpartitioned and copy things into it as needed.
Any tips?
Thanks.
