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.

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?

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.

Thanks

People have said to wait for version 8.2 of Retrospect which appears to be here.

Maybe time to move to RAID6 controller. I've seen folks on MacGurus talk about large, massive storage arrays and backups.
http://www.macgurus.com/productpages/sata/BurlyRAID.php
People have said that they backup RAID A to B. Or mirror two arrays.
Did you not like SynchronizePro? From March '09:

I have not heard of problems (very many) with SuperDuper and their support is always helpful.
A linux NAS server running linux backup or even Windows Home Server. People even use Windows to run Retrospect (runs better). Anything you find will likely take some time to setup and configure in the beginning, this isn't your proconsumer type of need.

Re-Creating Entire System on New Mac From External Drive Using Time Machine

Hi all -
Sorry if this question has been posted, I've look extensively and haven't seen it in this exact form, and I'm paranoid about this stuff. I also can't get a straight answer from Apple store employees.
I travel extensively with my MacBook, and when I'm home, I use Time Machine to back up all data from my MacBook onto an OWC external hard drive.
My question is, if my MacBook is ever lost, stolen, or damaged, and its internal hard drive is no longer accessible, and I have to buy a new MacBook, can I use Time Machine to access the backup data on my external drive and transfer it to my new MacBook's internal drive, thus re-creating my entire system on my new MacBook, including all settings, preferences, files, absolutely everything exactly as it was on my old MacBook?
This is by far the most likely need I'll ever have for this backup data, so if Time Machine doesn't help me to re-create my system exactly as it was on a new laptop, it's not of much use, and I'll switch backup software.
Related question - I read somewhere that Time Machine keeps making backups on your external hard drive until it runs out of space. Does that mean it literally uses up every bit of space on the external drive? Because overstuffing my old external drive is what killed it, and cost me a huge chunk of change and several weeks to get the recoverable data off the drive. Or does Time Machine know enough to stop backing up when there is only "X" amount of space left on the drive, and if so, at what amount of remaining free space does it stop?
Thanks for your help!

If you need to restore everything to a new Mac, you simply have your TM drive connected when you start up the new Mac and during the Welcome routine that runs when you start up a new Mac for the first time you will be presented with the option of migrating your user info, settings, files, applications, etc., from a Time Machine backup. You just click "Yes" and all your backed-up info will be transferred to your new Mac.
Time Machine continuous "cleans up" backups so you do not need to worry about TM pushing a drive to its capacity limits, or even close 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 external drive for time machine

This deals more with Time Machine in general rather than Time Capsule, but this seems like the place to post the question. Is is possible to make Time Machine only use a certain amount of space on your external drive for backups? Basically, I use the same external drive for my backups and for storing other large files and videos. Time Machine always uses up every last bit of spare space, so every time I want to add a new file I have to go in and manually delete an old backup to create space for the new files. Is there a way to allow Time Machine to only use a certain amount of space for backups, say 300GB, and leave the rest of the drive available for my other uses?

Hello coltonbh. Welcome to the Apple Discussions!
Yes, but you will basically only have two choices to do so:
1) Temporarily remove the TC's internal drive (voiding your waranty); repartition it, and then, reinstall it, or
2) Create a disk image on the TC's internal drive the size you need for file storage. Time Machine backups should leave this image alone. The only problem is that Windows/Linux will not be able to access these disk images ... so this would only work for Mac clients. You would create a disk image using the OS X's Disk Utility, not through the AirPort Utility.

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.

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

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.

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.

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.
