I want to use a nas drive for my time machine back ups.

Hi,
I'm pretty new to macs. I've set up time machine on my kids macs using a time capsule without problems.
Ive now bought my own mac and want to use time machine to back it up but only have a network hard drive to do it on. When I go to choose disk, I'm not given the option of the drive. I can see it in finder ok.
Is this possible?
Thanks
Roy

There's more to it than a "party line." Many folks who have started this, and thought it was going well, found it wasn't as reliable as they thought.
From a post in another forum (found by V.K.):
*The technical reason why Apple limits Time Machine to 10.5 AFP volumes appears to be to prevent disk image corruption. There were additional features added to AFP in 10.5 to support Time Machine. These presumably allow the disk image engine to force disk image journal data to write out all the way to the disk. Without such features, a network interruption can result in a corrupted filesystem on the disk image despite journaling. Remember, journaling relies on the journal being written all the way to disk before the changes take place. If you can't guarantee that (e.g., because of network/NAS buffering) then the journal is useless. Time Machine appears to rely heavily on disk journaling to deal with network drop-outs, interrupted backups, and the like. Take this away and your data is at risk.*
*If the NAS you are using supports these features it should report them to the OS and you should natively be able to choose that volume. If you have to trick the OS to use the volume it means the NAS does not support it.*
*To summarize: if you care about your backup data you should avoid using non-natively supported AFP servers.*
That only addresses Leopard, of course. Snow Leopard seems to have some additional requirements, that don't work with some NAS solutions that did work, to a degree, with Leopard.

Can I use One Hard Drive for 2x Time Machine Back Ups and another partition for all my data?

Hi Forum,
I am planning to but a RAID disc set up, but if i get a 2 disc set up, on one disc, can i have:
Time Machine back up for one Mac
Time Machine back up for 2nd Mac
Anothe partition for all my data.
then have that RAID'd to second disc?

no one?
and if this set up was on one disc, and one partition for one TM was for the Mini that has this drive attached, would TM back up this whole drive 2x TM Partitions and 1x partitions with data on, ok? it wouldn't get confused by trying to back itself up

Complicated corrupted main drive and lost Time Machine back-ups question

Here's tough one I can't pin down answers to: I have an iMac Early 2008 running Lion. The main hard drive system (probably) corrupted over the course of 2-3 months until it became unusable. I had Sophos on it, but removed it about a month ago and reliability improved but only for about a week. Finally the hard drive crashed. I used the Recovery partition while able to have Disk Utility add a second partition to my back-up drive, which contains Time Machine back-ups, my iPhoto folder and a few other files but no system. I installed Snow Leopard from disk to the new partition, checked the first partition, which seemed fine, then upgraded the Snow Leopard partition to Lion and updated and ran under a temporary user. Next I explored the main drive, which Disk Utility said was fine, but doesn't always show up. While in Disk Utility, I noticed that the first partition on the back-up drive showed up as empty! After some panicking, I've a second back-up drive on the way, but how do I access the TIme Machine back-ups, get my original user back and get access to over 15 years of files that are locked into that user?
My (2nd) back-up drive arrives tomorrow, so I'll able to get to work soon.
Thanks for any help.

Ok so wahat you mean is I need to name a partition "Time machine" in order for TM to back up any volumes and TM will always start with the volume titled Timemachine ?
so as I stated
A. All my OS applications _________Rename this to time machine or can I ues the volume name it is now?
B. All my files for those applications ---------Once that is done TM will back this up?
C. All My Itunes / Music etc---------Once that is done TM will back this u last?
Also I did a test run and I geet the error msg that the backup disk of my OS needs 1.36 TB but only 1.34 exists. The orignal OS disk has only 232GB of data why is tome machine asking for all that space?
I set the partition at 1.34 so there would be way more than enough space to copy.

HT201250 can an external portable drive be used for both time machine back ups and for additional storage or to sync files?

I use a seagate freeagent Go drive to keep a copy of important files. Files that I use with some regularity. I sync the drive every few days to ensure I have the latest. It is a old school method, but works well. I realize that not all things are "backed up" as they would be with a real back up, like time machine.
Can one device drive do both or should I use two different drives?

It is recommended that the TM EHD be at least twice the capacity of the Drive(s) it is intending to back up.
Note:
If you connect your current EHD to use as TM backup it will be Erased during the TM setup process.

External Drive Stolen with Time Machine Back Ups

Hello,
Sorry if this has been posted before. I scanned through a few pages of posts and didn't see anything.
My home was burglarized and they took my G5, Cinema Display and my 500GB external drive with my Time Machine backup data. My question is: How secure is the data on the external drive? Can the theif just plug in the drive and see all of the files or does TM password protected? My G5 was password protected to log in to it. Does that log in transfer to the TM files?
Thanks!
DH

As Donald says, the data can be accessed.
Your backups are as secure (or insecure) as your Mac -- if someone steals either, they can get at your data fairly easily, if they know what they're doing, unless it's encrypted.
It is harder to get at Time Machine backups on an external drive, because Windoze can't read it; you'd have to use a Mac (running Leopard or Snow Leopard) to access it.
But most theft is not for your data; it's to resell the hardware.

How do I use my backup drive for non-Time Machine stuff?

I haven't set up Time Machine yet because it wants me to completely format my external hard drive, and it seems to want to use it for TM backups exclusively?
However, I would also like to use it to store stuff that I don't want to keep on my computer, eg tons of photos, videos, stuff from my sister's computer, etc.
Is there a way to do Time Machine but also use the external hard drive for storage? I don't mind temporarily copying the photos etc that are on there to my computer while I format, so that's not the issue. I just don't want my EHD rendered completely useless to everything else.
Thanks

There are several ways to do exactly this.
If you partition the external drive, you can use one partition for TM and the other for anything else.
Even if you do not partition the drive, you can safely store other data in folders on the drive. Just to not use the folder that TM creates for anything. And it's best not to put files directly on the drive, in my opinion, but use folders for storage.
Just remember that whatever you put on the drive takes up room from TM and when the drive gets nearly full, TM will start automatically deleting older files from it's own folder.
I have my Tiger clone on my external TM drive in a separate partition and everything works fine.

I am using an external drive for a time machine backup. It has disappeared from the desktop. How do I get it back again?

My time machine backup disc, which has been working ok for a couple of years has suddenly disappeared from the desktop. The time machine program tels me it is unavailable. I have checked that the drive is working by booting up in Windows. and Windows can see it and read it ok. What has gone wrong, and how can I fix it?
I have tried unplugging it and reconnecting, but it is still apparently not seen by the system.
I could use Windows to reformat it, and start again, but this would loose all my previous backups, and I've no guarantee that the system would notice it even then.
Has anyone any ideas?

I think it's formatted on FAT 32 system, but I'm not sure. It's been working for a couple of years so far without any problems, so I think it must be compatible with Mac. The problem is that all of a sudden, the Mac doesn't acknowledge that it is present.

HT201250 I have thousands of pictures on my Mac. If something happens to my Mac I don't want them lost. I do time machine back ups to an external hard drive once a week. Is this good enough for making sure my pictures don't ever get lost?

Purchase a couple of these when they go on sale.
Start burning all the photos onto DVDs.
At least you'll have all your photos if your computer, time machine or any other backup you use goes bonkers.

Yes, it will do a full backup.
and if so, do I really need all the old backups on my smaller external drive?
Only if you want to be able to go back in time to those previous Time Machine backups. When you plug in the new larger external drive, you will only be able to go back as far as the first day you plugged it in and ran the first Time Machine backup on it.

I use an external hard drive as a Time Machine back up, but I want to use another external hard drive to save movies, photos on it, but it won't give me the option to save anything on the new external hard drive. Nothing is wrong with the external hard.

I have bought a WD My Book World Edition to use for back-up of my iMac, but when I try and log onto the drive with Apple time Machine (back-up software) or connect in any other way I get the message 'There was a problem connecting to the server "MybookWorld.local" The version of the server you are trying to connect to is not supported. Please contact your system administrator to resolve the problem'
It is a brand new iMac and running Lion OSX
Any ideas on how to solve would be gratefully received?

Followed the directions on this page and it worked!
http://forums.macrumors.com/showthread.php?t=1102423
Part One - Turn on SSH (in the admin panel)
[1] Go to to http://mybookworld.local
[2] login: username will be admin, password will be whatever you have setup. If you can't remember it should be in your Mac OS X keychain (Utilities > Keychain Access, search for "mybookworld"). If you have not changed if from the default the password will be admin as well.
[3] Switch to advanced mode.
[4] From the System tab, pick Advanced.
[5] Enable SSH Access, and click submit.
[6] Click on the network tab and then the LAN button
[7] Make a note of the IP address
Small, maybe obvious, but nevertheless important point: For the install to work, your NAS needs to be connected to a router with internet access.
Part Two - Install netatalk2.2
[8] Open Terminal.app (Utilities > Terminal)
[9] Enter the following command (substitute in 127.0.0.1 for the actual IP address you noted down in step 7), then hit return:
Code:
ssh [email protected]
[10] When prompted, enter the ssh password (will be welc0me).
[11] You are now going to download the installer. Enter the following command, then hit return:
Code:
wget http://mybookworld.wikidot.com/local--files/netatalk2-2-on-whitelight/install_netatalk.sh -O install_netatalk.sh
[12] Once completed, you will need to run the installer. Type:
Code:
sh install_netatalk.sh
[13] You will be asked a number of question during install, answer yes to all. When asked about the "DHX2 login process", I opted to install the modified version, so I can confirm it works.
[14] Once the box has restarted, you should be able to connect to your afp shares and continue to use Time Machine.

How do I prevent my hard drive being used for time machine back ups?

I want to install Snow Leopard but it tells me that the OS cannot be installed because the disk is being used for Time Machine back ups. I don't recall setting up my hard drive to be used this way (why would I?!) but now I can't seem to

Did you have TM turned on at any time? If so, and if you had no external hard drive attached, could it be that it created its own backup on a portion of your hard drive? I don't use TM, but I believe I read that this may be possible. Take a look at Disk Utility (Applications > Utilities) and report what you see on the left - under the top heading, is there more than one partition showing, such as here:
(I have two partitions: one for Snow Leopard, the other for Lion) - what does yours show?

How can I use one external hard drive for both Time Machine and iPhoto Library?

I have been using a 1 TG LaCie external hard drive for Time Machine backups. My (older) Mac has 160 GB and is almost full. I would like to move my iPhoto Library to the external hard drive, but I've heard Time Machine doesn't share one space well. Should I
1. create another partition (but will this erase what I've already saved) with Disk Utility? *I am running Snow Leopard*
2. create another volume to use for iPhoto, and if so, should the two volumes be of equal size?
3. leave it with one partition and move the iPhoto Library to the same partition with Time Machine back ups?
I know I don't need the entire 1 TG for back up of 160 GBs. Please advise the best path to take. Thank you!

You are getting incorrect information from your ASP. If you look at drive specifications the heat generated is no different for high vs low capacity drives.
I have upgraded the internal drive in my iMac 2007 with a 3TB Hitachi drive without any heat issues or other problems.
Larger hard drives have higher density platters so to access any given amount data the drives travel a shorter distance. Higher capacity drives should therefore run cooler than lower density drives because the drive spends less time spinning to access data.

Just got Prosoft drive genius 3 software, and it's telling me that the external hard drive that i am using for my time machine back up drive needs to be defragmented. is it wise to do this or should i not??

Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd.
Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set.
1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price.
I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there.
Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB?
Best would be to ask in the TimeMachine section Snow Leopard
https://discussions.apple.com/community/mac_os/mac_os_x_v10.6_snow_leopard?view= discussions#/?tagSet=1009
where there are some good FAQ and tutorials, and people that know the ins-and-outs and shortcomings.

Trying to use a new, larger external hard drive for my Time Machine backup. However, every time I start the backup, it gets started then fails. And, I can't delete the few files that did save on the external. Sort of a catch 22. Any ideas?

Is it a USB hard drive? USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice. Double check your profiler to make sure that is not a problem. If it is Firewire, make sure there aren't other firewire devices in use at the same time. I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

I want to use a nas drive for my time machine back ups.
