Swapping multiple hard drives for Time Machine backups

I would like to always have one external hard drive attached to my iMac for Time Machine backups, and another external hard drive off site - periodically swapping the two. The though is that if there is fire or theft, it won't help to have a hard drive onsite attached to the computer, because both the iMac and the hard drive could be lost.
Is Time Machine smart enough to allow me to configure two drives, so that whenever I plug in one of the drives, it can figure out what needs to be backed up?

I do the same thing, but I have to tell Time Machine each time I switch hard drives. I have not figured out a way to automate it. Might be better left manual.

Is it possible to use more than one external hard drive for Time Machine backups?

I want to use two hard drives for Time Machine backups.
Bigger one keep at home and be sure it is safe.
Second one (very small pocket size) keep with me for travels.
I want to backup to both drives to be sure I can restore everywhere and to be sure if something bad happened with my small travel disk I can restore from home backup.
Is there any problem with listed schema? Is it normal for Time Machine to handle backups for different drivers and keep everything consistent and smooth?

I really need some help! I have been using an Iomega NAS 1TB HD for the past year. And I received an error message. I believe I have ran out of memory on this drive.
Then recently in the last couple of months I got a ReadyNAS Duo 2TB with 2TB RAID. Should I switch my back ups to this one and delete the other back up file or keep the old back up image file on the Iomega?
Can I transfer the old image back up to this new ReadyNAS? How do I do this?
I appreciate any help.

I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

HT201250 new external hard drive for Time Machine backup suggestions?

Ok, I have 3 external hard drives; unfortunately I've used them on my PC and they are read only on my iMac. So, I need to buy a new external hard drive for Time Machine backup. I'm a little confused; can I buy any EHD and them format it so Mac can use it or are there special EHD's I need to purchase?
Anyone have a particular EHD that is working well for you? Thanks, Blue

Unless you need all three external drives for your PC, you can reformat in one of them in Mac OS Extended (Journaled) for use with Time Machine. However, since Time Machine backs up hourly, you'd need the external drive to be running constantly. That means ventilation of the drive becomes an issue since some, such as Seagate, can get very hot in their sealed enclosures. Some drive manufacturers try to get around this by spinning down the drive when not in use, but I've read complaints that that doesn't play well with a Mac. So whether you reuse one of your current externals or get a new one, it's a good idea to keep the drive's ventilation in mind.

Can you use the same external hard drive for Time Machine backups and as an additional storage drive?

I have an external HD that I've been using exclusively for Time Machine backups. I need to clear space on my hard drive, so I was thinking to move music & photos to an external drive. Wondering if I can use the same one I have (which I'll aslo keep using for Time Machine) or if I need to get another drive.

Hi Jossydtaylor,
Time Machine can use either an entire external disk or a partition of that disk:
OS X Mountain Lion: Disks you can use with Time Machine
http://support.apple.com/kb/PH11171
You can use Time Machine with a Time Capsule, and with USB, FireWire, and Thunderbolt disks. The backup disk can be directly connected to your computer or be on a network. If the backup disk has been divided into partitions, you can use one of the partitions.
If the disk is partitioned using the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine. The GUID Partition Table (GPT) partition type is recommended.
For more info on partitioning, see this article:
Disk Utility 12.x: Partition a disk

Cheers!

Using external hard drives for Time Machine backups

I would like to let everyone know about an important issue regarding what type of media to use, or better said not to use for Time Machine backups.
I tried to use a RAID 0 array disks ( FIY: RAID is a storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement.), but after a few minutes the backup suddenly stopped giving me a message of failing to write to the disk.
I tried to back up several more times, but the result was the same. I called Apple Customer Support, they said there was nohing wrong using a RAID 0 array disk combination.
I checked the RAID disks with disk utility, the disks were okay, but it did not solve the problem.
I reformatted the RAID disks, but that did no help either.
Then I used a different disk not part of any RAID array, and the Time Machine backup was able to successfull finish he task.
I called Apple to tell them about this issue, and they finall confirmed I was right:
Conclusion: backing up to a RAID 0 array disks using Time Machine does not work

Is there anything else on the drive? If not, just erase it with Disk Utility.
If there is, have you emptied the trash? That will take a very long time, and may present problems wtih locked files, permissions, etc. If so, see #E6 in Time Machine - Troubleshooting.

Can I use my 2TB Time Capsule ONLY as an external hard drive for Time Machine backups?

Hi...wondering if somebody could help me out there.
I currently have an older Apple 2TB Time Capsule (previous generation) which I'm using as both my WiFi access point, as well as my Time Machine backup location for both my iMac and my MacBook Pro.
We've been having slow WiFi issues in our home, and seeing as how this Time Capsule is a number of years old, were thinking of upgrading to the faster WiFi routers with 802.11ac capability. I'll be honest when I say we were considering other options, beyond the newest Time Capsule.
My question is, can we somehow use the 2TB of storage on our current Time Capsule for the purpose of backing up our computers with Time Machine, but NOT use the WiFi functionality of the Time Capsule itself?
I'm assuming if I manually plugged either my iMac or MacBook Pro (wired ethernet) into the Time Capsule, I could likely get that computer to recognize and use it for Time Machine purposes, but I'd like to use it to backup both computers, ideally wirelessly on the MacBook Pro.
Any help would be great.
Right now I'm running a DSL line into a DSL modem, which then runs ethernet into my Time Capsule. From there, I have a 4 port switch connected for wired devices (we wired our home with ethernet jacks in almost every room). We also have an Airport Express to extend the range of the network.
Thanks,
Jason

You can bridge the TC and plug it into whatever wireless router you buy.
There is no need to turn off the wireless in the TC.. but you can set it up as a secondary wireless network. That is totally up to you. I find the Gen4 TC very fast on 5ghz.. but you need it to be close to the computers.. in your case that should be dead easy.. simply plug it in by ethernet in the same room as the iMac say.. and set it up with bridge and the imac plugged into it by ethernet.. one computer then can access the internet and backup via ethernet with huge speed improvements.. the laptop can then use whatever your new router wireless network.. or the TC one if it is close enough..
So there are plenty of variations and your setup is easy to handle with the large amount of ethernet you have.
Just post again if you need specifics.. but I need specifics to give them!!

USB hard drive for Time Machine backup?

I'm looking for a USB hard drive that actually works with Time Machine. I have a Western Digital 320Gb passport HD. When I try to run TM, currently with Snow Kitty and previously with Leopard, TM seems to hang at 'preparing backup' and then I get error messages that the drive was unexpectantly removed, even though I didn't touch anything.
Assuming it is the portable Western Digital HD what is a good brand/make to use for TM backups. If the particular drive is not the problem, what should I look at?

Did you prep the drive before you started using it? Do the following:
Extended Hard Drive Preparation
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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. 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 Options 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.

IPod as Hard Drive for Time Machine

Is it possible to use your iPod as an external hard drive for time machine backups?

I have an iPhone now so I really dont use my iPod anymore for entertainment purposes...so I figured if I could use it for Time Machine backup instead of having to buy an external hard drive that would be preferable...does anyone know if you actually can use an iPod for this? and if so how do I go about doing it?

My external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive. Same thing has happened with Final Cut Express.

My new LaCie external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive.
The same thing happened recently between Final Cut Express and my other LaCie external hard drive used as the Scratch disk. It fixed itself.
I've run out of ideas. Help would be very much appreciated. Thanks.

have you done some searches on FCPx and time machine? Is there a known issue with using a TM drive with FCPx? dunno but ...wait...I'll take 60 sec for you cause I'm just that kind of guy.... google...." fcpx time machine problem" Frist page link
http://www.premiumbeat.com/blog/fcpx-bug-best-practices-for-using-external-hard- drives-and-final-cut-pro-x/
You cannot have time machine backups on your hard drive if you intend to use it in FCPX.
booya!

Do I need to use all the hard drive for time machine or can I partition it

Do I need to use all the hard drive for time machine or can I partition it

You cannot partition a TC disk.
See pondini about mixing data and backups.. but remember this.. the TC has no way to back itself up and TM cannot backup files on the TC. Anything not backed up on the TC will be lost at some future point.

Unable to select two drives for time machine backup?

I had a notification from Time Machine saying "This backup is too large for the disk..." and that I needed to omit items or select another drive. I've read online that it's possible to select multiple drives for Time Machine backups (so it switches between the available drives). When I go into Time Machine preferences and click "Select Disk" the drive I want to use in addition to my current Time Machine is there, but when I choose the additional drive I do not get the option to replace or "Use Both" (like pictured). Instead the additional drive is selected as the sole Time Machine and the current Time Machine drive is replaced.
In short, Time Machine is not giving me the option to "Use Both" - why would this be and how do I remedy this?
Thanks.

The reason is that that feature is Only offered in "Mountain Lion" OS X 10.8; and you are using "Lion" 10.7.
Hope this helps

Mac mini as an external hard drive for time machine??

I have a mac mini from a few years ago and it is never used. I was wonder if it could be used as an external hard drive for time machine. If this can be done how do I go about setting it up for this type of useage?

Thanks for starting this thread. I too am trying to use my old mac mini in target mode to utilize it's hard drive for Time Machine.
I hope to strip it down to just it's OS (10.5) and use the remaining hard drive space for Time Machine backup.
Is it possible to just have it running at certain times for regular back in target mode? Or do I have to keep it on constantly?
I fear having to restart using the "T" command each time. Isn't there a way to just have it sleep and then have the ability to wake it up as I backup or restore?
thanks in advance for any help.

Can not fine external hard drive for time machine sence lion was installed

I can not fine external hard drive for time machine sence lion was installed, it don't reconise it at all.

I have a Mac Mini (late 2009) and I have an iomega 1TB external hard drive connected to my mini via firewire and usb (usb allows me to use the usb ports on the external 1TB drive to daisy chain other devices). Since I installed Lion, my Time Machine and this 1TB drive (and its partitions) is finicky. Sometimes it is mounted and sometimes it is not. This issue has only surfaced post Snow Leopard and in the Lion era. I am not the first to say this but the whole reason I went Mac was b/c of Vista. I am beginning to think that Lion is the new Vista. Sorry for the latter, just venting... b/c this ain't the first issue with Lion.

Hard Drive for Time Machine for iMac with AirPort Extreme??

I just switched back to Mac after too many years with a PC. I bought an iMac 24" 2.8GHz with 4GB 667MHz DDR2 SDRAM and 750GB Serial ATA Drive.
I'm planning on adding an external hard drive for Time Machine to attach to my AirPort Extreme. From reading information posted on the Apple site and my AEBS I understand that it needs to be connected to the USB port on the AirPort Extreme.
While I may be opening up a technological "can of worms," I'd like to know what will be the most dependable drive 1TB, USB 2.0 that I can buy. Noise and bright lights are not a consideration here. I just want a drive that I can depend on to work with Time Machine. The "original" data will be stored elsewhere. I've heard of, read about and experienced so many hard drive failures that I'm getting "gun shy" about this subject. Please feel free to let me know what's good and bad. Thanks.

Here is a quote right from Apple's site today:
Quote:
AirPort Extreme lets you turn your external USB hard drive into a drive you can share with all the >users on your network. It’s called AirPort Disk, and it’s a simple and convenient way to share files >among everyone in your family, office, or class.
I tried to return my AEBS to Apple but I was a few days beyond their 14 day limit on returns (limit is bases on shipping date of the item in question, not when all parts of the shipment are received). Part of my reasoning with the Apple Store CS was the posts like yours saying that this couldn't be done. The Apple Store rep. and the tech. rep. that he claims that he spoke to said it could be done. The only way I could return the AEBS, according to the Apple Store CS rep., and get a new Time Capsule would be if I bought a hard drive and discovered that my AEBS would not work with the hard drive. No, I'm not a happy new customer. So, I want to buy a good, reliable hard drive and want to know which one to get.
