How big of an external disk do I have to use to back up my mac mini using the time machine app?
I have a new Mac Mini, and I wanted to begin using time machine to back up my files. I tried to use an external hard drive that is used for our other machines (PCs) and it would not allow that hard drive to be used b/c it did not have a valid file structure. I did not know how to fix that, so I was going to buy another external hard drive to support backing up the Mac Mini with OSX10.8.1 and a 500GB hard drive. I saw somewhere that as lonmg as I had twice the RAM (4GB) it should be ok, but that seemed to be too small. I was considering buying a 500GB if necessary.
Does anyone know if I can use a small 8GB flash drive to support the backups or do I need a 500GB or similar external hard drive to backup the Mac Mini with time machine?
Thanks.
It is recommended that Time Machine has its Own Dedicated Hard Drive that is at least Twice the size of the Drive(s) you intend to Backup.

How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac
How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac?
The question pretty much says it all.
I have a Mac Mini with an attached 3TB Hard Drive used for Time Machine Backups.
I have an Airport Extreme base station which services that machine plus several others.
I would like to backup my new iMac and a MacBook Pro to the Mac Mini.
What do I need to do on the mini to export that hard drive so that it can be used as a Time Machine target from the other systems?
All systems are running 10.6.8.Well you would have to do backups over a network which is much slower and has highest chance of becoming corrupt. I think your best option would be to get an apple time capsule to act as a network and back if thats how you wanna do that

I just purchased 2 WD TB external hard drives. I have one formatted to be used with the time machine and it is working well. the other that i am using to store large files is excluded from the time machine. I can't click on it and add as per instructions. It won't allow me to. I need to back t his up as well. Ive backed up this one so I am able to reformat it but it doesn't recognize the drive unless it is formatted in FAT which is what WD advices it be formatted in. It should be in Mac extended journaling but I can't get it to mount in that. Help?
In addition, TM will not backup drives partitioned in FAT as the OP stated his 2nd EHD is formatted. My recommendation to the OP is to reformat the 2nd EHD to Mac OS Extended (Journaled) and then include it in his TM backups. Of course in order to do this the OP must first move the data on the FAT partitioned drive to his internal HD and then once the EHD is re-partitioned correctly he can move it back.
In addition as Pondini mentioned the 2nd EHD must be directly connected to the iMac rather than be a network drive, TM is NOT, repeat NOT a network backup solution with the single caveat of using a Time Capsule backup. -
what do i do if i want to use a portable hard drive for backing up, if i also see
the time machine also on there?flora1917 wrote:

Do you mean you're already backing-up to a Time Capsule, and want to switch to using an external HD? If so, just format the drive and select it via Time Machine Preferences > Select Disk. See #21 in Time Machine - Frequently Asked Questions.
If you mean something else, please clarify. -
My mac book was incredibly slow. When I went to Mac store, they asked me to reinstall the OS with CD and not with the time machine. I reinstalled the operating system. But when I opened the applications, all those started as fresh applications as usual. I have the backup of all other data in another hard disc. But unfortunately, I forgot to copy the photos before reinstallation. I have those photos in my time machine back up. But when I opened time machine, it started like a fresh (very new) time machine and it started backing up my present OS (the reinstalled one). I cannot open the previous time machine, which is in the same hard drive. I wish to open the previous time machine to get the photos which are backed up previuosly. When opened the time machine disc (manually by clicking the icon), i can see all the thigs which I had previously in my macbook. But unfortunately, i cannot access those through time machine! Can anybody help me please?

How big should my external hard drive be for me to use Time Machine?
i am a student and dont have a significant amount of files and that on my computer so how big shuld my external hard drive be?
I will be using a normal external hard drive so will i be getting the full and the important features out of time machine if i do this?There are two questions you should ask yourself:
1. How long will it take me to fill up my internal HDD?
2. How far back chronologically do I realistically expect to have go to retrieve data?
I submit that in the vast majority of cases, a HDD of the same size as you have in your MBP will be ample. If things change, adjustments can be made well in advance. Its the very rare user that will generate multi GBs of data and file changes every session.
As an example, I have a 750GB HDD in my MBP and a 750 HDD dedicated to Time Machine. The oldest backup goes back 7 months. At the rate that I update Time Machine, I expect the Disk to be filled and start deleting old data in about 3 months. For me, that is more than sufficient.
There is another aspect of backup strategy you should consider. I would highly reccomend that you have a second external drive to store your most important files that may be duplicates of those in Time Machine. All HDD will fail. You just never know when that will happen. If your Time machine disk expires, this way you are not left in a calamitious situation.
Though some of my views may be in the minority, the final decision is always yours.

I want to set up the Time Machine and I would love to use the Time
Capsule but since I already have a wireless router I need suggestions on
what other
external disks Apple could recommend to use with the Time Machine and
how to configure that disk.
A complication that I need to resolve is the fact that I am using Vmware
Fusion to be able to use Windows on my Mac. Now it seems that Time
Machine is not backing up my files
on that virtual Windows without additional configuration and my question
is whether you can advise me here or whether this is only a matter for
the Fusion virtual machine.If you want to use Time Capsule you can.. you simply bridge it and plug it into the existing router.. wireless can be either turned off or used to reinforce the existing wireless.. eg use 5ghz in the TC which is much faster than your 2.4ghz.
You can also use a NAS.. many brands available but the top brands are synology, qnap and netgear readynas series. These will all do Time Machine backups although how well always depends on Apple sticking to a standard. There are cheaper ones.. I bought a single disk zyxel which was rebadged and sold through my local supermarket. It actually works very well for TM at least on Snow Leopard. Major changes were made in Lion and again ML so do not instantly think it will work on later versions. I haven't tried it yet with those versions.
Any external drive can be plugged into the mac. Use the one with the fastest connection or cheapest price according to your budget. USB2 drives are cheap and plentiful. But no where near as fast as USB3 or FW800. So just pick whichever suits the ports on your Mac. Interesting Apple finally moved to USB3 on their latest computers.
TM should exclude the VM partition file.. it is useless backing it up from Mac OS side.. and will slow TM as it needs to backup that partition everyday for no purpose.. TM cannot see the files inside it to backup just the changes.
You need to backup windows from windows. Use MSbackup to external drive.. if you have pro or ultimate versions you can backup to network drive. But MSbackup is a dog.. at least until the latest version it cannot restore the partition without first loading windows. There are about a zillion backup software versions for windows.. look up reviews and buy one which works for you. I use a free one Macrium Reflect which does full disk backups and is easy to restore.. to do incremental backups though you have to pay for it. -
I am looking to back up my MAC, and I need to know how big of an external hard drive I need
I am looking to back up my MAC, and I need to know how big of an external hard drive I need. How do I determine this?
Well, they recommend at least 2 - 3 times the size of your hard drive if you are using Time Machine because that keeps making backups until it runs out of space (and then deletes the oldest to make room for the newest).
However, if you prefer to have a bootable clone as a backup, you need about the same size as your hard drive since it is a perfect copy of your system (unless you want to partition and keep an older clone separately).
So, check to see how large your hard drive is and go from there. -

Please help new (senior) convert to Mac Pro (OS X). Am following the 'switching to a Mac' portable genius 2nd ed, and as it advised, I bought an external hard drive (a Mac My Word) and partitioned it with one partition for a secondary boot device and another for time machine. Book implied I needed both. Seemed to download OK but now when i plug in the external hard-drive it wants to reboot me fresh all over again. How do I keep the time machine partition going but have the secondary boot device only in case of emergencies? Do I 'eject' that partition- and if so how do I do it from outside the hard drive (I am not game to reattach it currently)
Launch the System Preferences application (under the Apple menu) and select the Startup Disk preference pane. Set your internal drive as the startup disk. Close the window.

Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Or you can simply use the Restore option of Disk Utility to clone the drive to the backup:
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive. -

I have reached capacity on my IMac hard drive. It is a 250 GB drive. I have an external drive backing up using the time machine utility. My question is once I replace the HD on the IMac, how do I load the new drive with the back up from the external drive?
So many possibilities.
I am not an expert, but I have learned this much is doable:
Buy an external enclosure to re-use you old drive.
Buy a new external drive at least as large as as your intended new internal drive. Make it self-powered.
Download CarbonCopyClone (free download, relatively small).
Make a CCC clone of the original disk on the new external disk
Install the original disk in the external enclosure.
Install the new disk in the main system.
Boot from that new external drive that has the carbon copy clone. CCC will be installed on it and it will be bootable.
Use CCC on the external to directly clone back to new drive you install in the main system (the "bootable" flag will copy).
NOTE THAT AT NO TIME IS YOUR ORIGINAL DISK BEING OVERWRITTEN IN THIS PROCESS. YOU CAN ALWAYS GO BACK AND REINSTALL IT.
Step 1 makes your old disk resuable as a spare copy for "anything".
Step 2 gives you something to use as CCC for after the recovery process.
Step 3 gets the software needed for cloning
Step 4 makes a bootable saved copy of your current system
Step 5 shifts your old disk to a usable place
Step 6 positions your new disk
Step 7 boots your existing install of OSX (just from a different drive)
Step 8 puts your original install on your new disk.
Now you have a bootable larger hard drive, and a bootable copy on a drive large enough to save all you can store on your new internal drive. And you have your old disk to use for "anything".
Now you have TM backup in one place, and CCC backup in another.
Two backups is better than one, and one of your backups is bootable in case of system failure. -
I have a Power PC G5 computer that I will soon be replacing with a current i5 or i7 Mini. How do I transfer the Time Machine files from the internal hard drive on the G5 to an external drive that I will later use with the Mini?
Hi, likely the easiest is to just poll the drive & get something like this...

i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard driveWelcome to Apple Support Communities
Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
