Can I dedicate specific folder in my external drive for Time Machine to download to

Is it possible to create a folder in my external drive and point Time Machine specifically to that folder to backup my computer? I have some files already on my external drive and want them separate from the backup files that Time Machine will create.

No, please carefully read Time Machine FAQs and also bookmark Time Machine Troubleshooting

My 320GB external drive for Time Machine now only has enough capacity to keep a backup of one day. All my other backups are gone. What can I do to fix this situation?

I've been using a 320GB external drive for time machine for the last several years. The backups always worked fine and when necessary I was able to look at & restore older data from the time capsule. Recently, I keep getting the message that a backup cannot be completed and an older backup will be deleted. Usually this wasn't an issue because I still had several months of information on disk. Now a one-time backup takes up 315GB and therefore I only have a backup of the previous day. I don't understand this because I thought that the backup only saves information that has changed and doesn't copy everything everytime. What do I need to do to get my backups to a reasonable size so that I can keep at least 1 month data stored on it.? Please don't tell me I need a larger drive ... that would be too easy.

Get a larger drive for your TM backups.
The recommended size is 3 times what you are backup. So if 315 GB is a backup then you need a 1 TB drive.

I've used an external drive for time machine which has important files on it. After trying to back up my computer, it suddenly needed to be "repaired" by utilities. Now it's not being "seen" at all! How do I recover my important files off the drive?

If the external drive can be seen at all in Disk Utility, follow the instructions for repair here.

HT3275 New macbook, old external drive for time machine

I got a new macbook pro a few weeks ago and set it up using my last backup from time machine. I want to use the same external drive for backups but there is no room. Can I delete all of the old files from the old computer or do I need to keep them?

As long as they're formatted HFS+, yes. Be sure there's enough room, though -- Time Machine needs considerably more room than the data it's backing-up. See #1 in Time Machine - Frequently Asked Questions.

Adding a Dedicated External Drive for Time Machine

Hello,
I want to use a dedicated external drive for Time Machine backup and another drive for a SuperDuper backup. Before even adding another drive, I'm already pulling and replacing usb connections from the back of my computer.
Can anyone tell me if a splitter is a workable solution? Something like this:
7-Port USB High-speed Hub with Splitter Cable -- http://www.shop4tech.com/user.htm?go=view_item&id=8997&r=183 -- or perhaps other recommendations ..
Thanks.

...I recall reading that USB 2 was faster ... but I think they said faster than FW 400, but the drive I have is FW 800.
USB2 is 480mbps and Firewire400 is 400mbps. On paper, this would appear that USB2 is faster than Firewire400. But USB2 cannot handle large data transfers very effectively. I can't explain the technicals, but suffice to say that the figures I gave of 40min-versus-2-hours-for-25GB is typical of Firewire400 versus USB2.
Firewire800 is 800mbps, so would potentially be even faster. However the physical hard drive that's installed in the Firewire enclosure would be the bottleneck as a normal "platter" hard drive is much slower than Firewire400 or 800. If it were an SSD drive, then you'd likely see a very significant difference.
But regardless, USB2 cannot keep up with a large data stream like Firewire can. Potentially USB3, which is up to 5Gbps, would be faster than either Firewire 400 or 800, although I suspect would be on par with Firewire3200 in the real world. However since there are no adapters for either USB3 or Firewire3200 for the Mac, it's a moot point for now. (Your drive is not USB3, there are only a few USB3 drives available, and you'd need a Mac Pro to add the adapter in anyway, if they existed.)
So are you saying that FW 800 is faster than USB 2.0 -- and that I should be using the FW connection to get better throughput? And that I can resume daisy-chaining multiple external drives through the one port?
Definitely Firewire would be faster than USB. And I have 5 external hard drives daisy-chained through a single Firewire800 port on my Mac. So daisy-chained Firewire is the way to go.
Like I said, for the small, incremental, hourly Time Machine backups, the speed difference is insignificant. But when the day comes that you have to restore your hard drive, (i.e.: hard drive dead so you buy new blank hard drive. Or you just want to replace with a larger drive,) if say your Time Machine backup is 80GB, that restore would probably take several hours over USB2. On my Firewire400 drive, my 100GB Time Machine restore of my Macbook Pro took about an hour and a half. (The data transfer was about an hour, but OSX took awhile after that to finish up the restore.) YMMV, of course, but IMHO, use Firewire over USB2 as much as possible. If you're lucky enough to have a Mac Pro or iMac and can use multiple internal hard drives or eSATA, then that would be even faster than Firewire800. Only owners of a Macbook Air or non-Firewire Macbook should resign themselves to USB2.

External drive for Time Machine

I want to use a 3 TB external drive for Time Machine to backup multiple 500GB hard drives in my Macpro. I have lots of large video files from HD cameras.
1. Will Time Machine backup all of the hard drives in the Macpro?
2. What is a good external hard drive to handles these types of files?
Thanks.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Can I use another computer as a external harddrive 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 your reply. I looked at the Troubleshooting, but can't find my exact problem. It is as follows:
I use a new iMac running Snow Leopard with a 500 GB external WD drive.
-I looked the other day to find that time machine had failed, and when I looked at the backups, there had not been a successful backup since September 2009. I think this is when I installed Snow Leopard...
-I went to run a backup, and it failed, saying I did not have room (I have about 220 GB to backup)
-I decided to format the external hard drive and try again from scratch.
-I began getting an error 11, and specifically -8062 and -36 (as examples) which specifically list files that it could not copy.
-I reinstalled snow leopard from disk.
-I excluded time machine from spotlight as recommended in some forums
-I started ommitting some of the files that were listed as not being bale to copy, but now its into my music, and that's half the reason I back up.
I am now backing up to laptop as above post, and if that works, I will conclude that the External HD has seen its day.
If I get the same errors, I will conclude (nervously) that my computer has issues.
Here is an example of an error message:
Error: (-8062) SrcErr:NO Copying /Users/Shared/Music/Compilations/(album name)/(song name).mp3 to /Volumes/Time Machine 20100504/Backups.backupdb/Riskin's Computer/2010-05-04-222232.inprogress/F9243DA..(many letters and numbers)...D19/Macintosh HD/Users/Shared/Music/Compilations/(album name)/(song name)
then below in another message says:
Copy stage failed with error: 11
Backup failed with error: 11
I get this same original error with different files, and with different error numbers.
Apple support told me that by formatting external drive, and reinstalling snow leopard, they were 99.9% sure it would be fixed, but it is not.
Frustrated,

Can I use an external drive for Time Machine and storing other data?

At the moment I have one external drive, a 500gb LaCie. My internal drive is 160gb. I don't think I'll be using all 500 of those gigabytes for a while, so I want to put them to good use. Can I make a partition on this drive and use that for Time Machine, leaving the rest of the drive for my documents and other files? If so, how would I partition the drive? I'm not fluent in Disk Utility and even though I'm pretty sure I know how to do it, I don't want to screw up. Also, how big a partition would you recommend?
While we're here, I have a second question, somewhat relevant to the first. Could I move my Time Machine backups to a second drive if I wanted to? Also, if I used a big drive (say 1tb) could I use Time Machine to backup my current LaCie to a partition on that drive? Thanks in advance.

Does that also mean that I could back them both up on a very big drive?
Yes. Time Machine will, by default, back up all of your external drives unless you specifically exclude them.
Also, will Time Machine backups eat all my space after a lot of usage?
It depends on what you do on your Mac. If you work often with very large files (video editing, heavy photo editing, big disk images, Microsoft Entourage data file, Parallels disk image file, etc) then your backup drive could fill up very quickly.
I use my Mac mostly for e-mail, web browsing, iTunes, iPhoto, and the occasional iMovie project. I have 92 GB on my main hard drive (60 GB of which are my iTunes and iPhoto libraries, and one iMovie project.) My Time Machine backups consume 155GB on my backup drive, and that's after using Time Machine for a full year.

How can I make more room on external drive for Time Machine?

I now have Time Machine installed and in use on my external drive, which also still has my previous backup on it which used a different system (Dejavu). The external drive's capacity is 74 GB; 58.22GB are used, my iMac hard drive (backed up with TIme Machine) has 38.12 GB used, which by my calculation means about 20GB of the 58 on the external drive are the prior backup. Is there a way I can erase this prior backup, which now duplicates Time Machine, thereby making more room for Time Machine in the future? For instance, if need be, can I erase the whole thing and reinstall Time Machine on it? Thanks!

James, if you open your TM drive, I'm guessing you see the usual System, Library, Users, and Applications folder along with a folder labeled something like Backup.bkup. (I'm away from a TM backup and I can't exactly recall the name of the TM backup folder.)
The DejaVu backup is just a standard file backup using 'rsync' so you can delete whatever you want by simply dragging it to the trash and emptying the trash. If the drive is bootable, you may not want to lose that ability. But assuming there's nothing in your user folder on that backup that isn't also on your computer, you can delete just about everything in your User folder on that drive. You can delete selected applications too. And if you don't mind losing the ability to boot, you can drag everything but the TM backup folder.

Auto mount/eject external drive for time machine backup/restore

I have an Iomega ultramax drive connected via firewire 800 for my Time machine backups.
This drive will automatically spin down after a period of non-use. I like this as it means lower power usage and lower risk of data loss (head crashes etc..).
My problem is, when the drive spins down like this, some file open operations pause until the drive spins up again. I cannot remember exactly which applications I have had the problem with, but I assumed that this was part of the OS. This delay can be up to 5 seconds or so and is really annoying.
Assuming this is not just a specific third party application thing. My suggestion to Apple is to do one or both of the following:
1) Multi thread the file open dialog (process?) so that is comes up instantly, and then adds the drive when it has spun up.
2) Modify time machine so that it can automatically mount/eject the external drive just when doing backups and restores.
Currently I have a bit of a messy work around to this problem where I have a loadd scheduled shell script that runs every hour that mounts the drive, runs time machine to backup and the ejects the drive. It works, but is not perhaps as nice a solution as it could be.
Does anybody else suffer from this problem?

Yes that is correct, the drive spins down and remains mounted.
To be perhaps clearer. The problem is not essentially a time machine problem, it is to do with whatever implements the file open capability that other apps use. In the above sitation, there is always a delay for the drive to spin up when I go to open a file (perhaps five seconds) in other applications. I assume this delay is caused by the file open process waiting until some data is retrieved from the external drive before giving me the option of choosing a file. This delay is annoying, as I do not ever want to open a file from my external drive (this is dedicated to time machine backups) when I am using pages, or any other application other than a time machine restore.
This particular issue is similar (but I suspect nowhere near as bad) as one of my pet hates about windows XP. In windows it appears that the explorer will wait for a response on all its connected drives (hard disks, mounted cds, network drives), so any sort of network connectivity or hardware delay will cause explorer to freeze. As explorer seems to be embedded in most things you do with the OS, this can cause anything or everything to freeze (web browsing, you name it).
In my setup, as I have the external drive totally dedicated to time machine backups, another thing that would fix the problem for me is the suggestion number 2 I suggested where time machine auto mounts for the backup and then ejects after the backup. With the feature, then the external drrive will only ever be mounted for short periods of time (the above problem does not ocurr if the external drive is not mounted), and when it is mounted it will be spinning, so I will never have my file open delay. I would however have a short delay when doing a time machine restore for the mount of the drive, but this is a much rarer event the using file open in all my other apps.
Thanks for the info on the feedback link, I will post this to that.

External drive for Time Machine and Firewire Hub

Just got a new iMac. My old iMac G5 was running 10.4.11 so no Time Machine. On the new iMac I am running 10.5.6 I find I have questions about how to go about making best use of this new facility available to me. Since my new iMac has only one firewire port (FW 800) I also need an additional port here.
My thoughts are to use an external drive connected with FW 800 as a Time Machine backup and use the (usually) extra FW 800 port to extend the FW 800 and I find I can get a dual interface drive with both FW 800 and FW 400, so I could use the FW 400 for FW 400 devices like other FW 400 drives and my video camera.
Currently I use SuperDuper to make clone backups of my HD on a weekly basis (I use 2 drives for this on a rotating basis). I plan to continue that in addition to the facility offered by Time Machine (on a separate drive).
My questions are...
Is it a good idea to use the extra FW 800 or 400 port on an external to connect other drives to use for clone BUs?
If that is a good idea...
What brand and size of drive to use for the Time Machine BU (FW 400/800 sharing)
A. Maxtor?
(I have several OneTouch II and OneTouch III that I use for clones, I have been using them for a few years without problem. I seem to remember reading about some problems with Maxtor, have I just been lucky?)
B. Newertech MiniStack v3 from OWC MacSales?
C. OWC Mercury Elite-AL Pro™?
If the OWC Mercury Eltite is a good choice...
Is a 750 GB large enough?
Is it worth it to get the 1TB Enterprise 7200RPM?
Any other suggestions?
Andy

i needed 3 drives in total so went with my 2nd choice of buying external enclosures and then hard drives,
at the end it cost me much much less so i endded up buy another as a spare,
so currently using 4 NexStart combo enclosure each one fitted with a 500gb hard drive,
i got one connected to my G5 and 3 connected by FW400 to my imac through a daisy chain,
for time machines it doesnt matter about speed so you dont need to use up the FW800 Port,
FW400 will be fine,
before this i had a USB2 WD Book and was using that with time machine and never had a problem through USB,
i always connect to a port i hardly use as i wont ever need to keep taking it off if i had to connect my camera to it for example....

Partition an External Drive for Time Machine?

I am new to the Mac world. I have a new iMac with a 1TB hard drive. I have a 2TB external USB hard drive I've plugged in and started using with Time Machine to backup up my Mac. But I'm thinking I'm wasting a lot of hard drive space which I could use for something else. Can I partition the external hard drive say into two 1TB partitions and use one for Time Machine and one for something else? If so, can I do it now that Time Machine thinks it has all 2TB? Or do I have to start from scratch? Thanks!

+Can I partition the external hard drive say into two 1TB partitions and use one for Time Machine and one for something else?+
You can, but it's not advisable. How are you going to back up the data on the other partition? If your internal drive is 1 TB, then 2 TB is about the right size for a TM backup volume.
If you place any value on your data, hard drives are cheap. Just get another one.

Using an External Drive for Time Machine and Other Things

I have a 2TB external drive which I use for Time Machine Backups on my 2 macs. The macs have HDs of 500GB and 160GB so the external drive has ample space for backups.
Is it okay to use the external drive for other things that I don't care if they aren't backed up (like digital copies of DVDs)? i.e. Will Time Machine cause any issues if a drive is used for more than just Time Machine backups?

Maybe. See #1 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

It's best to put such things in their own partition. See #3 in the FAQ.
You may also want to make separate partitions for each Mac's backups, if you're backing-up either one directly (ie, not over your network). See #4 in the FAQ.

Has Anyone Used the WD My Book External Drives for Time Machine?

I'm thinking of getting the Western Digitial 1 or 2 TB My Book (Pro Edition 2 or Studio Edition) External Drives for use with 2 MacPros. Has anyone used these and could I use them with Time Machine? Would I have to reformat them for Time Machine?
Thanks!
Ashley

You may, and probably want to format them, even if not TM use, I would anyway. Not everyone is happy with MyBook Pro and TM.
I buy bare FW devices and add disk drive of choice, or just use OWC
http://www.macsales.com/firewire and works well.
FW800 is also better on the new Mac Pro
