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.

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.

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.

Can I use the same external hard drive for time machine and storing other files

I have a 640GB external hard drive that I have been using for over a year for time machine backups. My mac hard drive is now starting to fill up and I am looking to move audio, video and picture files to my external hard drive. How do I do this without messing up my time machine backups? Can I do both on the same external hard drive? Do I just make new folders on the external hard drive to move the files I want? Thanks for the help.

If you move the files you will need to get another disk to back the files up to. You don't want to have only one copy of certain files (personal, professional etc.).

Can I use my external HD for Time Machine and still use it for storage?

I have a 1TB external HD and my computer has yet to arrive. I was planning on backing it up via Time Machine and I'm wondering if my external HD will still be useable as a storage device once I pair it with Time Machine.
There's no way the backup will take up the full 1TB of space, so I'm hoping it doesn't just go to waste >.<

If you really only want backups of the current contents, don't use Time Machine.
It's designed to keep copies of things you've changed or deleted for as long as possible. This allows you an excellent chance to recover a previous version of something you changed or deleted in error.
It also allows you to revert your entire system to the exact state it was in at the time of any previous backup, even if that's a different version of OSX. It's rare, but if an OSX update, or installation of a kernel extension or 3rd-party app makes a huge mess, it's much easier and more reliable than rebuilding everything.
You might want to review the [Time Machine Tutorial|http://www.apple.com/findouthow/mac/#timemachinebasics] and perhaps browse [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).

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?

Partitioned external drive for Time Machine and Daily storage

Now that I've partitioned my I Terabyte external drive to two partitions using the disk utility with one partition for Time Machine and one partition as my new "hard drive"...my internal drive on the MacBook almost filled....I wanted to move...pix, movies, music..etc to the new drive and have all future storage pointed to that drive not the internal drive....need to have space available on the original drive on the MacBook....How do I move existing stored data and point ongoining saved music..files...etc to the new drive...???
Thank you...Bob

You could use an application like CarbonCopyCloner or SuperDuper to copy them to the new partition, but it's probably just as easy to drag the files/folders to the new partition, then delete the originals.
and have all future storage pointed to that drive not the internal drive
You probably don't really want to do that. Files you're using will be accessed much faster if they're on your internal HD.
Another consideration is, you really should have backups of the moved files somewhere, in case you have a problem with the new drive. Although TM will back them up unless you exclude that partition, if the drive fails, you'll lose both copies.

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?

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....

Can't use two external drives with time machine

I have 2 external drives. I tell time machine that I have 2 and it asks if I want to use both. I say yes and it says it will alternate between them. However, after backing up to both, it then will invariably say that one doesn't have enough room for backup...as if it is trying a new backup...... rather than just adding changed files. Why is it doing this and how do I remedy?

It then will invariably say that one doesn't have enough room for backup
Unfortunately, these kinds of things are common with Mavericks. All that you can do is erase the drive and start over again with a new backup. Or, if you do not want to erase the drive, set it aside in a safe place and add a new drive....and Mavericks will make a full backup to that one to start things off.

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!

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.

Can i use my external drive for TM and files i don't want on my mac HD

my hard drive has a total of 232.57g which is not nearly enough space to save all my pictures, movies, etc. i've been using a 300g external drive to save my pictures, movies, etc. which is now full so i bought a maxtor one touch 4 750g to hopefully back up my computer using time machine, my 300g external drive, and whatever new pictures, movies, etc.
if i set up my new external drive for time machine can i still put the pictures, movies from my 300g external drive and whatever new pictures, movies, etc. on my new 750g external drive?
do i need to make a partition? if so can you tell me how?
should i not use time machine?
any information is appreciated

mac HD
capacity: 232.57g
available: 170.29g
iomega
capacity: 298.02g
available: 14.29g
one touch 4
capacity: 698.51g
available: 698.36g
thanks for the quick reply but i need to explain it better or ask, once all is backed up from my mac HD and my iomega external drive to my new one touch 4 i want to stop using the iomega since there isn't much room left on it
will i be able to add files directly to the one touch 4 without having those files saved to my mac HD like i do now?
or will TM remove my files the next time it backs up my mac HD since i won't have the iomega on anymore?

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.
