I am setting up Time Machine on 2 computers which will use the same external network drive. Should I partition the ext drive
Should the dirve on a networked external drive be partitioned to support the use of Time Machine on 2 Macs that are on the Network. The disk is a 2 Gig Drive and I would like to use some of the disk for external shared storage.
You are aware that there are problems with using NAS drive for Time Machine?

Time machine questions... how to use with an external drive etc.
Hi,
I am about to start using Time Machine. I have a few questions:
1. Can Time machine be used to restore data and applications / application settings?
2. I have a CalDigit VR eSATA drive which is 1TB RAID 1 which I was going to use as the Time Machine target drive.
Does Time machine store all of its data files in one main folder with many sub folders?
If my TM backup data takes up 600GB on the drive can I safely store other data on the 400GB or is it best to partition the drive HFS+ Journaled 600/400 and leave TM to its own dedicated partition?
3. Does TM keep adding data until it runs out of disk space and only then delete older BUs?
4. Is TM a good backup software for total recovery or is something like SuperDuper better? I would almost never use TM to recover a file that was deleted... but I am looking for a way to protect against data lost in the case of HD failure.If you haven't found this yet, take a look here: http://www.apple.com/findouthow/mac/#tutorial=leopardtimemachine
That should give you a rough idea of the "look and feel."
1. Can Time machine be used to restore data and applications / application settings?
Yes, unless you tell it not to, it saves everything (except some system caches, temp files, etc.). If your HD fails, you can recover your entire system to a new/repaired HD via your Leopard install disc (it has the restore utility) and your TM backups. OS, apps (Apple and 3rd-party), preferences, settings, data, the whole system.
Does Time machine store all of its data files in one main folder with many sub folders?
As you may be able to see in the video, the small Finder window is very much like the main one; you can see your data in the same way. TM presents a "picture" that appears to be a full, separate backup of the way your Mac looked at any time. Of course, that's an illusion. It only actually copies files/folders that have been added or changed since the last backup.
You can't tell which items are "real" and which are the "multi-links" representing a file that didn't change on that particular backup.
For more info on the internals: http://www.appleinsider.com/articles/07/10/12/roadto_mac_os_x_leopard_timemachine.html
3. Does TM keep adding data until it runs out of disk space and only then delete older BUs?
Sort of. After an initial Full backup, it does incrementals (hourly, if you let it). Then it converts the first of the day to a daily backup, which it keeps for a month, and deletes the other hourlies after they're 24 hours old.
After a month, it converts one per week into a weekly backup and deletes the dailies.
It keeps the weeklies until it runs out of room, then begins deleting the oldest. But because of the "multi-links," it doesn't delete it's copy of anything that's still on your internal HD. So it manages it's space and deletions automatically and intelligently.
4. Is TM a good backup software for total recovery or is something like SuperDuper better?
They both have their advantages and disadvantages. Many of us use a clone plus TM. The clone advantage is, of course, being bootable. TM isn't. TM's advantages are the very fast incremental backups (it doesn't have to examine every file and folder to see what's changed): the ability to restore old items; and the ability to restore your entire system to a previous state, even if that's a prior version of Leopard! -
How to set up Time machine for multiple computers
How to name and select for backup
A Time Capsule does not require you to do anything.. each computer will establish its own backup in a sparsebundle.. and keep it different from the other computers. It all just works. Mostly..!!

Setting up Time Machine with Snow Leopard and MyBook World Edition II NAS
I have just successfully set up Time Machine on my MyBook World Edition II NAS. It's not so straightforward, and the information on the Western Digital support site is either unhelpful or flat-out wrong, so here's a post that will hopefully save people in a similar position a lot of time and frustration.
Here are the key facts:
1. The MyBook World Edition II NAS does support Time Machine -- if you upgrade to at least firmware Release 1.01.14 (9/29/09). See http://www.wdc.com/wdproducts/updates/?family=mbworld. Amazingly, the Level I support people at Western Digital told me that Time Machine is not supported! I had to point him to this link.
2. MyBook World Edition II comes with a built-in user, WD_Backup, which appears to be the only user that can be used for the backup.
3. Follow the instructions here: http://www.wdc.com/wdproducts/updates/docs/en/appletimemachine.pdf. BUT, what the instructions don't tell you is the password for that user, which Mac OS will ask you for during the Time Machine setup. On my device, it was "admin" but other posts say the password can be "backup" or "wd_backup."
4. Ignore some of the misleading statements in the Western Digital "knowledge base." For example, it says Time Machine is not supported. That used to be true but with the firmware update, is no longer true. Also, some instructions direct you to make a partition on your drive for Time Machine using Disk Utility. This is not possible, as far as I can tell, because the MyBook World Edition II shows up as a "share," not a "device" in the system, and therefore Disk Utility does not see it.
5. The reason I wanted to set up a partition, where I could limit the disk space, is that I read that Time Machine creates daily backups, with incremental versions of documents. Thus, the Time Machine backup will eventually fill up whatever space is given to it. Since I could not partition the MyBook World Edition II, what I did instead was to enable the "Quota" functionality and then put a disk quota on the WD_Backup user. I hope this will do the trick. (I have the further issue of having two Time Machine backups, one for me, one for my wife. How our Time Machines will battle it out for the disk space, I have no idea.)
I hope that the Western Digital people will create greater flexibility for Time Machine users in future firmware updates.
Anyway, hope this helped.You do need to know that Apple may not support this: Here's the official word: http://support.apple.com/kb/HT1733 (Leopard) or http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html (Snow Leopard).
You may be able to get it to work successfully, but there's no guarantee it will work well, or in the future.
From a post in another forum (found by V.K.):
The technical reason why Apple limits Time Machine to 10.5 AFP volumes appears to be to prevent disk image corruption. There were additional features added to AFP in 10.5 to support Time Machine. These presumably allow the disk image engine to force disk image journal data to write out all the way to the disk. Without such features, a network interruption can result in a corrupted filesystem on the disk image despite journaling. Remember, journaling relies on the journal being written all the way to disk before the changes take place. If you can't guarantee that (e.g., because of network/NAS buffering) then the journal is useless. Time Machine appears to rely heavily on disk journaling to deal with network drop-outs, interrupted backups, and the like. Take this away and your data is at risk.
If the NAS you are using supports these features it should report them to the OS and you should natively be able to choose that volume. If you have to trick the OS to use the volume it means the NAS does not support it.
To summarize: if you care about your backup data you should avoid using non-natively supported AFP servers.
That post obviously applies to Leopard; Snow Leopard appears to have added some requirements, that are also not supported by all NAS devices: some that were working with Leopard no longer work with Snow Leopard.
As long as you understand the risks, it's your call. But do yourself a favor and maintain some sort of secondary backup, such as a "clone" via CarbonCopyCloner or SuperDuper, or some other backup app. (Many of us do that with any backup app: no app is perfect, and all hardware fails, sooner or later.) -
My mac book air connects to my network and gets internet access but airport utility cannot find my airport base station to set up time machine
airport utility cannot find my airport base station to set up time machine
Normally, AirPort Utility is not used or needed to set up Time Machine backups......unless a default setting on the Time Capsule to Enable File Sharing has been changed.
On the other hand, if you open AirPort Utility, a picture of the Time Capsule should be displayed. Are you saying here that the Time Capsule does not appear when you open AirPort Utility? -
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. -
How do I set up Time Machine to work with an Iomega network hard drive?
I have just bought a new iMac having switched from Windows, and am very much a beginner when it comes to all things Apple. Previously I had used my NAS hard drive with my old windows pc. i successfully used it to transfer a lot of data from the old pc to the iMac but can't seem to get it recognised when I try to configure time machine. I have downloaded the latest version of Iomega Home storage manager which appears in the application folder in the dock, but when I click on The HSM icon it just disappears and nothing happens. I can access the drive through the Bonjour service and can see its contents in Finder. I have looked through the forums here but much of the info assumes a level of knowledge that i don't have. Is there an 'idiot's guide' anywhere to enable me to set up time machine to use the network hard drive?
You would probably benefit from a couple of things, first going through these 2 links
Time Machine FAQs & Time Machine Troubleshooting.
If you still have questions there is a TM forum, because TM is part of OS X you will find the forum in the Snow Leopard forum. Click Apple Support Communities and in the search field type Snow Leopard. Once you are in the correct forum you can narrow your search by clicking Refine this list.

Having trouble setting up time machine.
I'm trying to set up time machine and I go to the program, click it on, and then I click "choose backup disk", but there is nothing there. Is there anything I am supposed to do beforehand to give Time Machine a backup disk to save in?
My next question isn't about time machine but it might be related. I have to reinstall windows on my mac. I had it before and somehow it caught a virus, so I had to erase and it went to ****....long story short, It broke, I fixed it. Now i have to repartition my drive though. I assume that I have to split it three ways, one for Mac, Windows, and Time Machine. My question is....I want to leave Mac with the most space of all 3, obviously....whats the minimum I can split it to to install Windows xp and get Time Machine working (unless I'm way off and time machine setup is a different way)?So one can't back up to a partition on the main disk with Time Machine?
The iMac comes from the factory with a single partition. If you want TM to backup to a second partition on the iMac internal drive, you will need to Partition the drive using OSX disk that came with the iMac (this erases every thing on the hard drive) and reinstall the OS from the DVD.
But, I do not recommend that approach. Backups are generally needed if your hard disk crashes. If you are backing up to a partition on the internal disk, you will lose your backup if/when the drive crashes.
The only reason to use TM on a partition on the internal drive is if you are doing a LOT of version sensitive work (meaning you made need to look at yesterday's work on the same project). But most applications can be set to do incremental change backups of individual projects making TM a ppor choice anyway.
Buy an external drive for the TM backup.

I'm still learning the whole Mac thing but these are great machines! I purchased a MacBook Air 13" and then thought I should also get a MacBook Air 11" for travel. When I set it up at the Apple store I told the assistant the exact same name for each machine, i.e., "my name and MacBook Air." What I want to do is go back in and rename both of them adding the 11" and 13" designation to the name so that when I set up Time Machine or whatever else I know exactly which machine is what. I'm sure it is very simple but I cannot seem to figure it out. Help please. Thanks.
Go to System Preferences - Sharing and change the computer name there. You can also, optionally, change the name of your hard drive to further clarify the origin of your backups. Click once on the "Macintosh HD" on your desktop, then click its name to allow you to edit it.

How do I set up "Time Machine"
I am on http://support.apple.com/kb/HT1427, but the information given on how to set up "Time Machine" doesn't match with the prompts my Mac mini is giving me.
The support site says I will be asked,
But I don't get this ^ prompt. The prompt I get says "Choose a backup disc." And when I click on "CHOOSE BACKUP DISC" (my only choice) it brings down another drop down menu and my only two choices (prompts) are "set up time capsule" and "cancel." When I click "set up time capsule" my computer searches for an "air port utility" It then tells me I don't have one and then I am stumped. I don't want to install "Time Machine" with an "air port utility." (I don't even know what an air port utility is.) I want to use an external hard drive I bought so that I'd have more space as my backup disc.
Any suggestions on how I can install Time Machine? My Mac Mini is 2 and a half years old, but I just recently started to use it as my "default" computer.Okay. I was able to change it to my external hard drive. Now, do I need to keep that drive connected all the time or will it update if I eject it and then (days later) reconnect it? And it said that it might take a long time to back it up. Will I get some kind of notification when it's done? (Sorry. I am technoloically inept. I know.)

Setting up Time Machine - it won't recognise my external hard disk - help!
I'm trying to set up time machine to use as my back up system. I have an external drive plugged in by USB that the desktop and finder are picking up - but when I got to 'find disk' as I am setting up Time Machine - it doesn't show any disks to choose from.
Has anyone had this problem?
Thanks!The disk is probably not formatted correctly for Time Machine. There's a free download on my website, 33thingsbooks.com, that describes in great detail how to format a TM disk; you might find that helpful.

Which external hard drive should I use/choose as I am setting up Time Machine on my MacBook Pro 15 for the very first time?
Any of these SATA HDDs that are at least the same size as your internal HDD (preferably larger capacity). In addition you will need an enclosure, preferably one with a Firewire as well as a USB connection.

Not sure how this all works but my problem is this: I have attached an external hard drive to my mac snow leopard 10.6 and am trying to back up my computer through Time Machine. When asked to select the drive as part of the set up, there is nothing to select. The box is empty. How do I set up Time Machine for back ups with an external drive? I am running Airport Extreme WI-FI (VERY confusing as I did not know the difference between Extreme and Capsule). Now to add another component...how does Icloud figure into all of this if I want to back up my computer systems, documents, etc? Is this a simplier way as long as I download Lion? Help!!!
Hello,
Problem is likely the Format of the External drive, for TM it needs to be Mac OSX extended Journaled & GUID Partition scheme for Intel based Macs...

(To Install OSX on an IntelMac the Drive it needs the GUID Partitioning scheme mentioned at the bottom.)

There are other free options for backing up if interested! -
How do I set up Time Machine to backup to an external hard drive on my wireless router?
I have just set up an external hard drive to my wireless router and am now wanting to set up Time Machine to back up to the hard drive. I can see the hard drive in Finder and can even send files to it manually. I just don't see in setting up Time Machine any option to backup to that hard drive. Is it even possible?
Well, I figured out a way around it that works for me but may not be suitable for everyone. Instead of connecting the external hard drive to the router I tried connecting it directly to my computer. I then right-clicked the hard drive's folder on my desktop, clicked "Get Info" and checked the box that says "Shared Folder". I then went to the bottom of that window and under "Sharing & Permissions" and next to "Everyone" checked that they could all "Read and Write".
The hard drive is now shared over my network, so when I got on one of my other Mac's that I was wanting to set up Time Machine with, the Time Machine Application had no problem finding the hard drive and backing up to it.
I have all computer's setup for file sharing too, so that may need to be checked as well.
This was a simple enough fix but the reason I said that it may not be suitable for everyone is that the other computer's backing up to this hard drive via Time Machine is now reliant on my computer being turned on. I'm okay with that though. -
Setting Up Time Machine over a Network
Time Machine Back up Problem
This gets a little complicated, but here goes.
Mac A with Drive A
Mac B with Drive B
Both running Maverick and networked using AFP & SMB
Having set up Time Machine on Mac A
Mac A would back up to Drive A and Drive B
We then tried to set up Mac B:-
Mac B would back up to Drive B does not see Drive A
Having tried several ways of trying to get it to work and different settings, without knowing what we have done, (if anything) now…
Mac A backs up to Drive A but does not see Drive B
Mac B backs up to Drive B and Drive A
Help!?Check around the forum, you are one of very very many. It doesn't matter what WD say, do you see a Certified by Apple notice on it?
