Hooking up external hd to airport express to use with Time Machine

Hello, I would like to hook up my external HD to my airport Express and wirelessly still be able to use it for backing up and additional storage. Is this possible?? It will be hooked up via USB. It currently is sitting behind my iMac (2009) and hooked up to it via USB. I don't like how it is noisy and how it pauses my tasks sometimes while the external starts up every half hour or everytime I open certain applications.

it's possible (even though not officially supported by apple) but you'll have to restart your TM backups from scratch. remote backups are stored inside sparse bundles while directly attached ones are stored directly in a folder on the drive.
so you might want to erase your current TM backups first to free up space on the drive. but don't delete them from finder. erase the drive from disk utility.

I bought an external hard drive for backups to use with Time Machine, but however when I try to connect it with the other windows laptop it doesn't work ? intact it doesn't work on any other device except my MAC ?

Do not worry about it.
Time Machine needs that your external drive is formatted in HFS+, or better known as "Mac OS Extended (Journaled)". This filesystem is used by Apple on Macs and Windows cannot read or write drives formatted with this filesystem, being this the reason why all your devices do not read the external drive except your Mac.
You can only use your external drive to make Time Machine drives. If you store anything different, you may damage the Time Machine structure, so it is better not to use it as a drive to store other data. Instead, get another external drive to do it or create a second partition on the external drive formatted in FAT32 by using Disk Utility > http://pondini.org/OSX/DU3.html FAT32 can be read by Windows PCs

What size should external back-up drive be for use with Time Machine?

I am very new to Macs.
My iMac has a 500GB hard disc - not much on it yet.
I want to back the hard disc up daily and automatically to an external hard drive using Time Machine. So that I could restore everything if the iMac failed.
1. Does the external hard drive that I buy need to be larger than the iMac's hard disc, e.g 1Tb? Or is 500Gb enough in my case?
2. Should it be pre-formatted for Mac when I buy it? Or do I have to do this?
3. Should it use firewire or USB?
4. Presumably I need to leave the external drive plugged in all the time? Or will this stop the iMac from switching on and off?
I really want the easiest solution possible as I am not very techie and I want the minimum amount of fiddling with it. So I am confused between whether to choose a Western Digital My Book Office edition or Studio edition, 500Gb or 1TB, firewire or USB, or maybe a Lacie?
Would be grateful for advice.
Thanks very much.

Welcome to the Apple forums. If you have a 500G external disk, that will work fine for quite a while with hourly, daily and weekly backups, but sooner or later it will fill up, but then it begins to delete weekly backups. The same will happen with whichever size of external disk you buy: sooner or later. . . . Nonetheless, that disk will be fine for most purposes. I have 250G and use a 200G partition for my MacBook Pro and while that was fine, it tends to delete weekly backups so I have about 6 months of backups stored. (I also make other backups of all data).
It may be preformatted, but that is unlikely. Use Disk Utility (in Applications>Utilities) and use MacOS Extended, which is selected in the Partition tab (you do this even if you only use a single partition).
The system works with either Firewire or USB 2..
You do not need to leave it in all the time. If it is connected, it will make the backups, if not, nothing will happen and it will indicate that the next backup will occur when the disk is attached. To disconnect, you would highlight the disk in a Finder panel and press the Eject icon (not while TM is running of course) then disconnect the cable.
I am not able to suggest which disk is best, although my LaCie one has not missed a beat. Others may have a different idea. Try a Google search with the disk manufacturer's name and "problems" or somesuch. No disk is perfect of course.

Does it create a problem if I only connect the backup external drive every few days for use with Time Machine? Should I have purchased Time Capsule instead?

After a near miss with my 4-year old MacBook, I finally wised up and purchased a WD My Passport for Mac to back up my hard drive. I connected the Passport today and have performed the first full backup. However, I do not wish to keep it permanently connected to the laptop. Does this create a problem if I only connect the drive every few days? Should I have purchased Time Capsule instead?

Hello,
I don't think it'll cause a problem, but I'd disable/turn off Time Machine before disconnecting, then turn it back on after you connect it again.

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

Quiet external hard drive for use with Time Machine?

Few questions related to Time Machine:
1- what external hard drive that would be good to use with Time Machine, that also runs relatively quietly? Since TM runs 24/7, am looking for one that is quieter than my current G-tech.
2- Please confirm what size is optimal relative to the size of the internal hard drive.
3- I currently use a separate external hard drive as my bootable disc. Is it possible/preferable to have these be on one and the same drive?
Thank you.

1. I like these (have three of them) - literally whisper quiet:
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
2. You should allow 2 - 3 times your internal drive's size for TM.
3. No, it'd be best to be on another drive - you can create separate partitions, but if/when the drive fails, both of your backups would be gone. So, keep your clone on a separate disk. In fact, it's good to have two different backups.

External HD for use with Time Machine

I have a new MacBook Pro with 320GB HD. I want to buy an external HD to use with Time Machine for a back up. HOw much capacity should I be looking at for the external? Is 500GB enough or is it possible to partition a 1TB unit for use as backup and extra storage (photos, music, etc...)?
Thanks.
This should have been posted in the late model forum. Sorry.

Can I use disk utility to partition once plug in HD?
Yes, you can. Click the Partition tab. Click options and set the partition scheme to GUID. One option is to have one partition a bit smaller than your internal HDD, which you can use for a bootable clone (SuperDuper or Carbon Copy Cloner).

External hard drive to use with Time Machine? Thoughts? Mac newbie.

Hello. Switched to an imac and have loved the experience. Was just about to buy an external hard drive when apple announced the time capsule. I've been holding off thinking I would purchase one but now I'm re-thinking it.
Between music, videos and pictures, I currently have about 400gb of stuff (and it will grow). My main concern is backing up (archiving) a copy of these files. Backing up other system files is a second concern after that.
I'm thinking of buying a 1TB external hard drive, firewire capable, partitioning part of it to be an archive drive, and the other part to use with time machine. Skip the time capsule.
Will that work? Other recommendations?
If so, any recommendations on a quiet, reasonably sized (i.e. doesn't take up the entire corner of the desk), 1tb external hard drive?
Thanks.

Clayton, if you're only backing up one Mac, then you can purchase any good, reputable 750 GB or 1 TB external drive.
Considerations:
1) Reliability is key here. You want a drive that works. Various people have complained about Western Digital (me included), so take that into consideration.
2) Quiet is important. You have a quiet computer -- why louse up the working environment with a noisy drive?
3) FW (Firewire) 800 is faster than FW400, which is faster than USB. But once you get the initial backup done, it really doesn't matter how fast the drive is, because it works in the background and doesn't hamper your work. And if you DO need to restore your entire computer via Time Machine (I've done it), speed is less important than reliability. Even if it takes 3 hours, you'll be grateful. So while some may counsel you to get a 'fast' drive, reliability is more important.
4) On FW versus USB, you'll hear many claims. Again the key is reliability versus speed. A good USB drive is fine for what you are doing; FW is faster. Some folks have had problems with one or the other, so hear what they have to say.
5) Every drive dies. That's true for any electromechanical device. Don't think you've solved your backup problems by plugging in a drive and walking away. Your most critical files need a second backup, be it to a DVD, CD, thumb drive, network drive -- something. The more critical it is, the more backups you need. If you're writing your Ph.D. thesis, by definition you can't have too many backups
6) Convenience matters. You can 'roll your own' drive if you have experience -- buy a case, buy a drive, assemble, etc. But it's many times easier, particularly for a Time Machine backup drive, to just buy a reliable (there's that word again) external HD off the shelf.
7) Finally, follow directions. Apple tells you how to set up a TM drive. Do it their way. That means, format the brand new drive and make it a 'GUID' partition. Use the Apple Disk Utility. Follow directions.
Good luck,
Steve

Partitioning an External 320gb drive for use with Time Machine and...

I want to be able to use my Western Digital 320GB external drive for use with Time Machine and to use as extra storage space on both my Mac and when I boot into Windows Vista.
Is this possible?
I was playing around in Disk Utility and would I partition the part I want to use for Time Machine with the Mac OS Journaled, and whatever I want as space for windows, use a MS - DOS format?
Has anyone done this before?
Cheers-

Unless you are using 64 bit version of MSWindows (64 bit XP/Vista), it won't be able to handle a disk with GUID partition table (GPT). Disks with Apple Partition Map (APM) or GUID partition table are the only ones that Time Machine will work with (not MBR disks). Note also that the MBR/APM/GPT are at the DISK level and not the partition level, so don't mix the format with partitioning scheme. Time Machine disks are meant to live in the Mac universe (for now, anyway) and sharing with the MSWindows 32-bit universe is not possible.

HT201250 I've just used an external drive to back up my Mac with Time Machine. I have Lion, but didn't click and check the "Encrypt Backup Disc". What should I do? Can I delete the external drive and start again, or can I encrypt later?

I've just used an external drive to back up my Mac with Time Machine. I have Lion, but didn't click and check the "Encrypt Backup Disc". What should I do? Can I delete the external drive and start again, or can I encrypt later?

I guess if stolen or lost it would protect my "stuff", and if I'm travelling would protect my privacy.
You must understand the purpose and implications of encryption before deciding whether to use it.
Encryption locks your data with a password. If you forget that password, the data is lost beyond any chance of recovery. Neither Apple nor anyone else will be able to help you recover that data if you don't know the password.
By the same token, the password must be strong enough to provide the security you want. For example, if you're the potential target of industrial espionage by a government or large corporation, you need the strongest possible password. To create and manage such a password safely is a task in itself, not to be undertaken lightly.
If you're only concerned about casual snooping by someone with no special skill, a weak, easily-remembered password is appropriate.
But regardless of the strength of the password, if you lose it, the data is gone forever.
Another point to remember is that if you encrypt your data on one storage device, you must also encrypt it on all other storage devices that would be accessible to the same attacker. Otherwise the data isn't protected. For example, if you keep your computer and your backup drive in the same room, and the internal drive of the computer is not encrypted, then there's no point in encrypting the backup drive.

Airport Express Model A1088 with Time Capsule Model A1254 configuration problems.

I have a Time Capsule Model A1254 and an Airport Express Model A1264. I run OSX 10.7.4. When I try to configure an older Airport Express Model A1088 the Time capsule does not recognise the older Airport Express after I configure it using Airport Utility version 5.6.
Can anyone help please.

What do you mean "the Time Capsule does not recognize the older AirPort Express"?
Sounds like the AirPort Express needs to be reset and reconfigured.

Can external disk added to time capsule be used with time machine?

I have a 2011 Apple Time Capsule with 2 TB of storage, which I use for Time Machine backups. I would like to add storage, or alternately just use a higher capacity hard drive for Time Machine backups. Can I attach a 3 TB external backup drive to the Time Capsule's USB port, for example, and use that for my backups instead of the internal hard drive? Apple says you can't do this with the Airport Extreme, but doesn't say whether it will work with the Time Capsule.

"OS X Time Machine supports compatible unencrypted USB disks connected to AirPort Time Capsule (802.11n and 802.11ac), and AirPort Extreme (802.11ac).": Meaning All Time Capsule Support it.
See the topic about Time Machine support for USB disks in this Apple Support document:
AirPort base stations: About USB disks - Apple Support
Time Machine backups are supported via USB hard drive connected to the AirPort Extreme"ac" version.
Time Machine backups were not supported via USB hard drive connected to earlier versions of the AirPort Extreme.
Some users who tried this on earlier version AirPort Extremes seemed to have some success with Time Machine backups....some had moderate success and some had no success with this.

Any Recommendations for External HD to use with Time Machine?

Have been using Time Capsule wireless as my drive for Time Machine back-ups for a couple of years with mixed success. It also serves as a wireless router for internet service between all devices in my household.
Was recently recommended to me to invest in an external firewired hard drive to use for Time Machine so now I'm presented with a dilemma: Which one to choose?
Need 3 Terabytes and I'm looking at the Iomega Mac Companion (3TB) but see that Apple has discontinued selling it from its store and there's an issue with using USB and FW simultaneously.
Looking for feedback from anyone whose used this device and/or recommendations on another 3TB drive to purchase.
Thanks in advance.

From that broad page The hatter suggested, these specific enclosures (with or without a drive pre-installed) are pretty good.
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
The one at the bottom that says 0GB is the same enclosure empty, so that you can pick a separate drive mechanism to install in it. That way you can order the exact drive you want, instead of having them choose from what they have on hand.
Wireheads will choose the 0GB and install the drive they prefer, most "regular" folks just buy it with a drive already installed and it works (after initializing) right out of the box, no assembly required.

What sort of external drive to use with Time Machine

Hi all,
I was wondering if there are requirements to the sort of external drive Time Machine can use: does it have to be a FireWire drive or will an USB drive suffice? Additionally, what would be the best type?
Wil Dieteren

Time machine will per default do incremental backups on an hourly, daily weekly and monthly basis. Therefore you need an external harddrive that is larger than the harddrive you are backing up. Depending on how many changes and large files you work with, the requirements for the right size may vary.
I'd suggest getting an external HD that is at least 150% of your HD. 200% would be more generous.
I just bought an Iomega MiniMax 500GB and it works great with Time Machine (my iMac's HD is 320GB).
