Using Time Machine and external USB drive for multiple Macs

I just bought a 1.5TB external portable drive. I have 4 macs in the household that might have about 400 - 500 GB of total HD capacity for the four of them. I am very confused on whether to create a separate partition for each mac, or let Time Machine manage the entire, single-partition drive.
The reason I ask is because I have run into issues with a smaller external HD where it didnt seem to know to remove old backups to make room for new ones. But, its' possible the 750 GB drive was too small to do what it needed to do.
So, I am looking for some definitive information on the best way to do this. Obviously, i'd rather leave the 1.5TB as a single partition, and hope (and expect) Time Machine to manage the backups of the four macs in such a way that it can properly make room as backups are added to the drive.
THoughts?

You can do that, but not simultaneously. TM only has one destination a a time; you can back up to the TC, then select the external HD via TM Preferences, then switch back.
I've been down the road of using SD (cloning) and am ready to move on to another backup strategy. Cloning works fine but it dedicates a drive 100% of the time where TM doesn't.
I don't know what you mean by that. I use CarbonCopyCloner (similar to SD) in addition to full TM backups, so I have two separate, independent backups, on two separate drives, and get the advantages of both. You can partition an external drive (but not a Time Capsule), so you could have your clone on one partition, and other things in one or more additional partitions (I do that as well). As long as the "clone" partition is the same size as your internal HD (or at a minimum, at least 15% larger than the amount of data on it), you can use the rest of the space for anything else.
See #5 in the Frequently Asked Questions *User Tip* at the top of this forum for detailed instructions on setting-up a drive for Time Machine. The same procedure works for setting one up for a clone and other partition(s), too.

Using Time Capsule and External FW Drive for TM Backups

Wondering if this can be done, or if anyone is successfully doing it.
Here's what I want to do:

One thing I did with an old 2.5" 80GB HD in an enclosure that I like a lot is put 10.6.2 on it along with Disk Warrior 4.2, Tech Tool Pro, and Drive Genius to use as a startup and repair disk.

Back up using time machine and external hard drive

Hello,
I am having a difficult time deciding the best way to back up important documents.
I have:
1TB internal hard drive
3 TB external hard drive and
1TB external hard drive
I currently have about 1TB worth of data to be stored, but that will increase to about 1.5TB once I get a bunch of stuff off the HD camera's hard drive. I would like to keep my internal hard drive somewhat free to keep the computer running fast, but also want to make sure I am properly backed up.
Should I put ALL (or nearly all) of the files on the 3 TB external hard drive, and have time machine back that up and not worry about the rest? I'm a little weary about putting all of the files on one device even if it is backed up by TM.
If I do this, do I need to back up the 3 TB external drive in addition to using TM?
Thanks!

Can i use time capsule as external hard drive for both mac and windows

I have a mac book pro, ipad and iphone and ipod and a windows pc
Can i use time capsule as a external hard disk only for all of the above ( including windows ) without the back up activity for mac ?

You cannot access the TC from iOS devices without a browser. eg filebrowser.
Can i use time capsule as a external hard disk only for all of the above ( including windows ) without the back up activity for mac ?
Yes, with the following proviso.. the TC is not able to back itself up.. so if you store files on the TC without backups one day you will discover all your files are gone because of a hard drive failure of the TC. TM also cannot backup TC.. so you will need to buy a proper backup software.
It is also much slower than a real NAS..
And windows can be a bit painful.. especially windows 8.. other versions should work if you spend the time getting everything set right.

Can I view photos and movies from my external hard drive? I used Time Machine and a WD Passport for backup. Since my drive on my MacBook Pro is filling up I was planning to delete some of the movies and photos.

Hello, eco1.
Thank you for visiting Apple Support Communities.
This sounds like you are wanting to move your iTunes media folder to an external drive and have iTunes this folder from this location. If this is the case then I would recommend taking a look at the article below.

Using Mac Mini, Time Machine and External Hard Drives as a Backup Server

Hello...
I own a graphic design studio and have been looking for a long time to create/buy a no-thinker backup system for my macs. I have 4 workstations that I would like to backup to one central "server".
So what I was thinking was buying a Mac Mini, 3-4 external USB 2.0 Hard drives, external Blu-Ray burner and upgrade all our systems to OS 10.5. What I need to know is, will each work station with Time Machine on it back up across the network to a specific drive on the Mac Mini? If I have each workstation automatically mount one external across the network onto the desktop, will Time Machine recognize that hard drive as a legitimate drive to backup to?
Having the external Blu-Ray disc burner will give me the ability to burn data to a disc so I will have a way to take some of my information off-site. Since we are a graphic design studio, we use large amounts of disc space and regular DVD-R (4.6 gigs) is just not enough to back up some projects.
Can someone enlighten me, and tell me if this would work or not. It's the only way I can see me creating something that has enough space, will back up automatically across the network and allow me to make off-site copies of my data without spending $5,000.00.
Thanks for any comments you might have on this topic.

I'm a member of a freelance graphic artist team and have been scraping by with my MacMini and CS3. I recently obtained a used iMac (approx. 2 years old) and, instead of painstakingly transferring everything left on the Mini to the iMac, I wanted to know if it's possible to turn the MacMini into a pseudo external hard drive using the FW800 port.
I already had an external attached to the Mini and plan on using that as well, but I tend to hoarde information and run out of space really quickly. So keeping the mini around, preferably in a way that I can access it as an external through my iMac, would be perfect. I have very little experience with networking and don't have a wireless connection (yay modem cables!) so I don't quite know how to figure this out.
Has anyone done this? Would a FireWire 800 work? Would I need to set up a network between the two and use them as independently connected computers?

I can't use Time Machine with a USB drive plugged into an Airport Extreme.

I connected an external drive to the USB port of an Airport Extreme, intending to use it with Time Machine and one of the laptops in the Wi-Fi network (call it Laptop). The drive is visible from the Disks tab of each computer’s Airport Utility but from nowhere else, in particular not to Laptop’s Time Machine preference.
Laptop is relatively new and arrived with Mavericks. Time Machine used to work on Laptop before I upgraded the rest of the network (a desktop Mac Pro and another laptop) from OS X 10.6 to Mavericks.
The drive is formatted as Mac OS Extended (Journaled). I have tried other external hard drives, with the same behavior. The desktop correctly use Time Machine to back up its internal drive to another internal drive. Another possibly relevant factor is that our DSL connection has recently been upgraded, and now uses a 2Wire modem that provides its own router, so Airport Utility’s Network Router Mode is set to “Off (Bridge Mode)”.
I would be grateful for suggestions of what to try next.

Using Time Machine with External Hard Drive

Hey everyone,
I had a few questions about Time Machine that I hope someone could answer for me.
I bought my first external hard drive in August, the 1 TB WD My Book for Mac and when I set it up, I configured it to Time Machine, and not the WD software.
I have an extensive music collection, which was my main reason for buying the external hard drive in the first place.
Anyway, when I plug in the hard drive and let Time Machine do the back up, I've noticed that it's backing up the same files every single time, and is eating up a lot of space on the hard drive.
Since I am mainly using this drive to store my music, I was wondering if there was an easier way to do things:
-Is there a way to not back up my documents, photos, applications, etc, every single time I plug in my HD?
-Is there an easy way to find my music on the drive? For example, some Time Machine back-ups have different files on them... i.e. my back up from August 10th has certain music files that do not exist on my backup from November 10th, as I deleted them from my computer after they were backed up to the external HD. I'd love to be able to see all of my music in one place, rather different versions of my music folder on different days.
Any help would be greatly appreciated.
Thanks a lot.

Hi,
1. Your Time Machine should should do the full backup of your computer just once and then only diffrences between backups - whenever you plug in the drive.
If that's not the case something is misconfigured.
2. You can exclude folders (documents, pictures etc) from being backed up. This is in in Time Machine Options (right bottom corner.
3. The drive is (most likely) indexed by Spotlight. However, provided those are backup files I would advise against browsing and searching them directly. This can damage the backup itself.
4. I cannot work out the exact scenario you are using - but the ideal (proper one) would be to have all your music library on your computer and only backup on your external drive. This you should not have to browse and use until you need to restore files.
5. If you keep your music library solely on the external drive - it should be not in the backup files.
Also such practice is risky as all drives crash sooner or later and you will lose your music.
Best would be to keep all music on the computer and backup onto your external drive.
Or
if the music library is too big for your computer you may keep it externally - but Isuggest you get one of the external hard dirves with RAID1 or higher. This will keep your music safer lest one of the drives packs up.
Let me know if you want me to elaborate on any of the aforementioned.

Using Time machine and external HD at the same time

Dear All
I'm intending to buy an external HD both for the purpose as a external HD and for time machine use.
Is this possible? If so, how do I configure it?
Thanks.
Jojos

Apple Partition Map works just fine on an external HD (including booting from a clone made with SD). GUID is only required for the internal HD on Intel-based Macs. There is a lot of misinformation going around on this topic.
Is Apple spreading the misinformation Barry? This OP originally asked about Time Machine and an external drive. He later asked about bootable backups. I tried to take all that in consideration in my reply. Apple has consistently said in everything that I have read in the Knowledge Base that when using Time Machine with an Intel Mac to use the GUID partitioning scheme.
There are also recent posts around these forums, as well as around the internet, where folks have had bootable volumes that were not GUID and they encountered strange behavior on their Macs that they report was resolved by making sure that their bootable volumes on external drives were in the GUID partitioning scheme.

Time Machine and External Hard Drive wireless backup over airport extreme

Ok can this be done? I have an external HD that I used a firewire to connect to my macbook pro and it backed up my movies,photo's etc without a problem.
When I realized I could plug the HD into the back of the extreme I tried that and I can see the shared HD in my finder but I cannot get time machine to backup wirelessly now and I can't see my previous back up in Time machine but I can see it when I look on the HD.
Can I continue to do my backups over the extreme wirelessly? How do i do this? Or do I have to plug the firewire and mac into the HD each time I want to back up using time machine?
Thanks,

I hope that support is added to the airport extreme. I would be disappointed in apple to learn that they have disabled it for the airport extreme and connected hard drive in order to only sell another piece of hardware (time capsule) that is simply the airport extreme with a hard drive built in.
There are reported work arounds for getting the airport extreme and external hard drive to work with time machine. A couple google search results outlined the process, it didn't look too complicated. I would prefer it was a feature and not a work around though.

Using Time Machine from external hard drive to start using a new MacBook

I recently totalled my MacBook (white) and am now looking to replace it with a second hand MacBook. I have an (un-totalled) external harddrive and have been using Time Machine to keep everything backed up. I found a second hand MacBook at a reasonable price but it runs OSX Tiger, whereas my old one ran Leopard. So my question is, will it be possible to plug in my external harddrive and restore everything, including the operating system, on this new (used) MacBook, or should I be looking for one that runs Leopard?
Many thanks for reading!

You can restore from Time Machine using Leopard or Snow Leopard only. What I would do if I were you is buy either of the MacBooks, but make sure you get a Snow Leopard install disc--either a retail one if you buy the Tiger MacBook, or the install disc for the pre-loaded software on the SL MacBook.
Use the SL install disc to completely erase and (re)install Snow Leopard on the MacBook. Since your Mac will be second-hand, you should fully erase it and start fresh, just in case there are some nasty little malwares left behind or other problems the original owner didn't want to deal with.
After the install, use Migration Assistant to get your data off the TM drive.

Time Machine and External Hard Drive

I have a 1T external hard drive and Time Machine has backed up my entire Powerbook G4 laptop on it. I would like to free up space on my laptop by deleting some things that I want to save on the external drive, but don't need on the laptop, how can I do this? Every time I try to delete something from the laptop, it simultaneously disappears from the external drive. Please help!
Also, I keep reading about partitioning - what is this and how do I do it?

Hi
I think the point to address is that an intrinsic part of "backing up" is that you always have two copies of something. One original, and one if you lose the original, either if you accidentally delete it, or the hard drive crashes, etc. What you want to do is backup a file through Time Machine, and then delete the original - which is NOT a sensible backup procedure (because now you still have only one copy of your file).
That aside, Time Machine is designed to be a continuous backup of your system at any point in time. So if, last week, you had a certain file A on your main drive, but you deleted it yesterday, you can check in Time Machine and you'll see it in last week's backups but not in any you made today. You should always use the Time Machine interface to do this - don't go into the backup folder yourself and try to look around (and certainly don't delete anything you find there), since that will be misleading.
If you did want to delete ALL copies of a certain file from your backup, you should go into the Time Machine interface, locate a point in time where that file exists, highlight the file and go to the Action (gear) menu in Finder and choose "Delete all backups of this file".
It seems that what you actually need to do is make an archive of files you don't need on a regular basis (which can then get deleted from your main drive). Burn them to a CD or DVD, or copy them to another hard drive, but don't delete them from the Time Machine backups (better safe than sorry).
Partitioning is a way to convert a physical drive or other storage device into one or more logical volumes, so that the Finder sees them, and displays them, as separate drives. So you could have a single external drive, but create three separate partitions (using Disk Utility) which mount as three separate drives. Under Mac Help, search for "partitions" - there are several useful documents there.

Problems with time machine and external hard drive

Hi all
In 2009 with my imac I bought a WD external hard drive which the computer says is 148GB formatted. I recall that the hard drive contained folders with files for the running of the hard drive when I bought it - and after it had been plugged in to a mac and used as a time machine, it no longer worked on windows computers.
Now I have used 195 GB on my computer's internal hard drive and wish to stop using the external hard drive as a time machine and instead use it for swapping files between computers and the like.
How can I wipe the time machine back ups and start using it as per usual again? do i need to obtain the WD files from somewhere?
thanks in advance
Nick

Hi Nick,
Avoid the WD files completely, not needed & often a problem.
You need to erase the Drive, & to use it on both Format it MS-DOS/FAT32, on the Mac or PC, but will have a 4 GB filesize limit, as well as other limitations.
One option not mentioned yet is MacDrive for your PCs... allows them to Read/Write & Format HFS+, so no need to reformat it...

Can I use Time Machine as a backup drive for my Vista 32 PC?

I cannot see any of my Mac computers or Time Machine on my network through my Vista PC, even though I have a wireless card in the PC which can connect wirelessly. I have my PC sitting next to my Time Machine that is the hub for my network. I am connected to the internet via ethernet connection daisy chained through my Time Machine which is connected to my cable router.
I cannot figure out why my PC cannot "see" my Imac, emac, Time Machine, and macbook that are all connected to my wireless network. The PC and Time machine are the only devices with an ethernet wired connection.
I would like to use the Time Machine's 1 terabyte drive to back-up my Vista PC.

I would first set up my mac and vista to do simple file sharing and then work my way from there. If you are unable to figure out simple fire sharing i would go look on other forums or advice. Its rather simple to do but it can also cause a lot of headaches. I have wanted to connect my mac and windows server to my network for a while and just recently figured it out.
