Time Machine with two hard drives?

I have a Mac mini running 10.5 Server that operates as my home server.
Is there any way to assign two separate hard drives as being available Time Machine network backup drives? IOW, if I had six Macs on my network and I wanted three of them to back up to Time Machine Drive #1 and the other three to back up to Time Machine Drive #2, is this possible? If so, how? It seems like Time Machine Server will only allow me to assign one drive as a network backup volume.

OK, here's the deal with TM. First is to know to what TM will backup:
Requirements to use Time Machine
Time Machine is only available with Leopard (10.5.x)
1. External FireWire or USB 2.0 drive
2. Time Capsule
3. Drive shared by a Mac running 10.5 or later using File Sharing
4. Drive shared by a Mac running 10.5 Server
5. SAN volume managed by Apple's Xsan file system
A TM drive must be partitioned with either APM (PPC) or GUID (Intel) and formatted Mac OS Extended (Journaled.)
Second, because TM is an incremental archival backup system the backup drive should be at least twice the capacity of the total capacities of the drives it backs up.
Now, each Mac on your network can use TM to backup their computer to a drive selected in the TM preferences on their computer. Multiple machines can backup to a single TM backup drive. TM will create separate backup folders on the target drive for each computer. Each computer needs to have a unique Computer Name (Sharing preference.)
Note that this is set up on each computer on your network, not through the server itself. As far as I'm aware TM only backs up to one drive. Thus, each networked computer can backup to a drive. The server on the other hand has its own separate TM backup.
You will need to manage the exclusion list to minimize space usage on the backup drives. Most likely you would want to have each client machine only backing up a Home folder. I would set up a /Home/Applications/ folder on each client machine exclusively for third-party user applications unless all applications are installed exclusively on the server.

Time Machine with multiple hard drives

I use a very large external hard drive for time machine. I back up to this time machine, the two hard drivs that are inside my macbook pro, 512GB ssd, and 250GB SSD that is in the optical drive. I then backup a 1TB portable hard drive which holds all my movies and then I backup another 1Tb portable hard drive which holds all my "reserve" files, which means they are files that are no longer important to be on my computer. Old pictures, music, etc.
Now, I can't plug all of these drive's in at once. So, let's say I have to do a backup and I have nothing plugged in but the time machine external hard drive. Will it only backup the two hard drives that are in my computer and then later somehow let me go and restore the other drives? Or will it attempt to restore all 4 drives at one time? Because if the one in my computer mess's up, the other's may not be messed up and I do not want it to restore those.
I have used Time Machine before to restore my system. But never since I have started adding extra drives for Time Machine to backup.
I am also planning on adding, yet another drive for it to backup which is a 1TB portable hard drive that I keep raw files on for photography. I'm just curious how this works when and if the time comes.

well superduper is FREE, CCC isnt.........CCC can do the daily updates etc,. Superduper DOES NOT. the CCC and Superduper CLONES are bootable.......so, if your HD crashes, you can throw in the CLONE, and youre back and running in mins, rather than hours etc .
You should NEVER consider a backup a "backup", ........2 copies is 1, and 1 is none.....always have 2 copies of important files / pics etc etc,......... DECADES of work have been lost by people who thought their stuff was safe because they had a (meaning 1) backup.
Simplicity? Yes, Simplicity is my religion. CLONE your HD with programs and settings, ......and use a 2nd HD updated daily / weekly etc (preferable 2 such 'seecond' harddrives, copies of each other) with all personal stuff / work / pics / vids/ documents.....
superficially time machine is simpler, "smack a button and everything backs up".......in REALITY however when it "all goes up in flames"................the pro method (and my method) is QUICKER and more reliable by far to get down and running.
Ive restored other peoples from total crash and burns via Time machine.......and "my" way............my way always ends up faster by a mile. Also personal / work etc files are kept autonomous to the system data / programs OS,.....as it logically should be.
Time machine is the fastest incremental backup........but its as slow as paint peeling if you need it in case of a TOTAL CRASH.......wherein a bootable clone can be thrown in , in less than 20 mins.

Operating system not found when deploying to machines with two hard drives using MDT 2013.

Computers with two hard drives will not boot after the install OS step in the task sequence. I get the "An operating system wasn't found. Try removing drives that don't contain an operating system" error. I am able to get the
machine to boot by swapping the hard drives' boot order, but the task sequence won't complete after this. The deployment works fine on machines with one hard drive, and I'm not getting any errors from the task sequence. I'm deploying windows7
enterprise x64 using MDT2013. This is a new custom image and task sequence generated using MDT2013. I can't remove the second hard drive because there are scripts that run on the second hard drive during deployment and also because I don't desire
to remove and re-install 250 hard drives. I've not experienced this problem with earlier versions of MDT.

The bdd.log file you sent does not show two internal drives, it shows only one.

Can i use time machine with a hard drive connected to the airport extreme?

Just wondering if there is any news on this since the last post was in 2008.
The Apple website info regarding the Airport Extreme mentions attaching a hard drive to the Airport Extreme, but I can't see whether that could be used for a Mac using Time Machine.

You can attach a hard drive, but Time Machine backups to a drive at the USB port at the AirPort Extreme are not supported by Apple, so it's not possible to say what your actual results might be.
If you decide to try this, it would be wise to have a secondary backup plan in place as well.

Using Time Machine with External Hard Drive

Hey everyone,
I had a few questions about Time Machine that I hope someone could answer for me.
I bought my first external hard drive in August, the 1 TB WD My Book for Mac and when I set it up, I configured it to Time Machine, and not the WD software.
I have an extensive music collection, which was my main reason for buying the external hard drive in the first place.
Anyway, when I plug in the hard drive and let Time Machine do the back up, I've noticed that it's backing up the same files every single time, and is eating up a lot of space on the hard drive.
Since I am mainly using this drive to store my music, I was wondering if there was an easier way to do things:
-Is there a way to not back up my documents, photos, applications, etc, every single time I plug in my HD?
-Is there an easy way to find my music on the drive? For example, some Time Machine back-ups have different files on them... i.e. my back up from August 10th has certain music files that do not exist on my backup from November 10th, as I deleted them from my computer after they were backed up to the external HD. I'd love to be able to see all of my music in one place, rather different versions of my music folder on different days.
Any help would be greatly appreciated.
Thanks a lot.

Hi,
1. Your Time Machine should should do the full backup of your computer just once and then only diffrences between backups - whenever you plug in the drive.
If that's not the case something is misconfigured.
2. You can exclude folders (documents, pictures etc) from being backed up. This is in in Time Machine Options (right bottom corner.
3. The drive is (most likely) indexed by Spotlight. However, provided those are backup files I would advise against browsing and searching them directly. This can damage the backup itself.
4. I cannot work out the exact scenario you are using - but the ideal (proper one) would be to have all your music library on your computer and only backup on your external drive. This you should not have to browse and use until you need to restore files.
5. If you keep your music library solely on the external drive - it should be not in the backup files.
Also such practice is risky as all drives crash sooner or later and you will lose your music.
Best would be to keep all music on the computer and backup onto your external drive.
Or
if the music library is too big for your computer you may keep it externally - but Isuggest you get one of the external hard dirves with RAID1 or higher. This will keep your music safer lest one of the drives packs up.
Let me know if you want me to elaborate on any of the aforementioned.

Time Machine with 3 hard drives + Dual boot Leopard vs Tiger questions

My situation began with two 160GB HDDs that I have been using under Tiger. One is the boot drive and the other is a data drive. I bought Leopard and also installed a new 320GB HDD but as yet I have not done the OS upgrade or even formatted the HDD. I need to gain some understanding before I proceed. My first choice is just to clone Tiger onto the new (bigger) HDD and then upgrade it to Leopard. (Note that this post is not meant to be a discussion of the best way to get the OS upgrade completed.) After that I could wipe the two 160 giggers to serve as backup space for the 320, but can anyone tell me: Is Time Machine compatible with using multiple HDDs for backup data? It may not be as relevant if the first answer is positive, but I also would like to know: Does Time Machine requires use some kind of special hidden partition for storage (or is just any empty space on an HFS drive sufficient)? If any HFS space will work, will Time Machine preserve the other files that are already there? And lastly, if I reboot into Tiger, mount the drive that has the Time Machine archive on it, and write/delete/edit the non-Time-Machine data there, will Time Machine freak out the next time I use it in Leopard?

...snip...

Yes this will work AOK. Have done this myself so can confirm.
It may not be as relevant if the first answer is positive, but I also would like to know: Does Time Machine requires use some kind of special hidden partition for storage (or is just any empty space on an HFS drive sufficient)?
No special 'hideden' partition required. It simply creates a specially named folder to keep/manage its data backups.
If any HFS space will work, will Time Machine preserve the other files that are already there?
Yes it will.
And lastly, if I reboot into Tiger, mount the drive that has the Time Machine archive on it, and write/delete/edit the non-Time-Machine data there, will Time Machine freak out the next time I use it in Leopard?
No it will not.

Using Time Machine with 2 hard drives in an iMac...

If I get the iMac configuration with an SSD and a 2TB HDD drive inside, will Time Machine easily back up both? I guess I'm wondering if Time Machine backs up more than one drive automatically. Thanks.

About TM "Backup Drive is Full"
TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Time Machine "thins" it's backups; hourly backups over 24 hours old, except the first of the day; those "daily" backups over 30 days old, except the first of the week. The weeklies are kept as long as there's room.
So, how long a backup file remains depends on how long it was on your Mac before being deleted, assuming you do at least one backup per day. If it was there for at least 24 hours, it will be kept for at least a month. If it was there for at least a week, it will be kept as long as there's room.
Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.
Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive.
Having a sufficiently large enough backup drive doesn't prevent this problem but it can help provide a longer period of time before the problem occurs.
If this is something of concern for you then you should opt to use a different type of backup utility and a different backup strategy.

Is a WD My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive bootable with my Powerbook G4 12" PPC 10.5.8?

Sirs or madams,
Is my Powerbook G4 12” PPC 10.5.8 'bootable' with a Western Digital My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive? Western Digital says officially no, but that it MIGHT be. I primarily live in China and bought a datastorage.com.cn Clearlight s400+ external hard drive enclosure with a 320GB disk drive a few years ago in China. My computer 'boots' fine from it, but since I got it in China all the paperwork, etc. is in Chinese; my Chinese isn't quite sufficient enough yet to read it. But there are references to something called "SATA", whatever that is.
My level of computer 'under the hood' knowledge is extremely low. I've been told that SATA has some relationship as to whether or not an external hard drive will boot a computer via the Firewire connection, something relating to 'interface', which I assume is how separate electronic gadgets work, or don't work, with each other.
I frankly don't care much for computers, the internet, or their related gadgets such as all these fancy phones. I longingly reminisce about the days when there were no such things. I use a computer & the internet because I have to, and unfortunately unlike a car where one doesn't have to have 'under the hood' knowledge to operate it, just knowledge of the steering wheel, brake, gas, etc., one seemingly must know a ridiculously great amount of 'under the hood' knowledge, including jargon, to operate computers.
So, please try to respond accordingly; thank you.
If this particular external hard drive won't, for certain, be bootable with my computer, can you advise as to what readily available brand/model would be in the 3TB range for a similar price, roughly $150ish??
Thank you very much.

Mr. BGreg,
Thank you very much. "...under the covers...". I think you meant "under the hood", as in a car. I suppose "under the covers" would be man/woman interfacing, which I am familiar with!
Actually, I'm back in the US now for a few months. I looked at the OWC web site, but only cusorily so far. I'll contact them; they appear knowledgeable about Apple computers.
As to what you wrote about Western Digital's cases, I certainly wouldn't want a poor case. In China I had over time gotten 3 different external drive cases, 3 different Chinese brands, and separately bought Hitachi brand disk drives that 'simply' plugged into the cases. The drives are roughly 80GB 120GB and 320GB. The two larger ones are in cases that have Firewire plugs/jacks, which are bootable with my computer.
So my understanding, as you wrote, has been that my Powerbook will boot from an external hard drive, provided it connects via Firewire, and the disk drive itself is 'normally' formatted with however my computer's own disk drive is formatted, (HFS OS extended (journaled) or some such??). So I was left wondering why Western Digital would indicate that even though their such-and-so external hard drive case/drive was Firewire capable, that they would then say it would not be bootable with my Apple PPC computer......
Well, anyway, since you indicated Western Digital's case quality is suspect, then I'll try OWC and disregard Western Digital.
Naturally, OWC should be able to address this, but your thoughts are also welcome. You mentioned the OWC cases are good with Apples. Would the disk drives OWC supplied with the cases also be of relatively dependable quality?? From my so far only cursory look at their web site they appear to have various options, including case only options where I could insert my own or their own drives. These sorts of options seem preferable, also along with quality components.
My Powerbook has been in use since 2004. In China I put in a 1.25 memory 'chip' in the bottom and installed the 10.5.8 operating system, which I understand are the maximum workable with my Powerbook. When I inquired with Chinese friends if my 1.33 GHz processor could be taken out and a more powerful one put in, they said it wasn't feasible because in my particular computer my processor was, as I recall them saying, soldered/'permanently' connected with the 'motherboard', that it would just be easier to get a new computer.
I would be with them and they would nonchalantly open it completely up showing me all its tightly arranged 'innards' while at least giving it a good internal dust/dirt clean job for cheap lunch and a beer (& so much dirt/dust/lint there was!)...these are the same folks who build the things of course...fast moving hands with tiny screws flying everywhere, but everything 100% all back in place when finished.
My Chinese friends also said that nowadays Apples are not as well built as when my Powerbook was built, that nowadays an Apple's life expectancy was considerably lower, so I fear that when I get a new computer that, though it will be more up-to-date and powerful, etc., it most probably won't last near as long as my Powerbook has. They also said that in an older computer the fan was often the first component to go bad, and if a new one couldn't be easily found, as they said was my case, then you're just left with having to get an entirely new computer. Part of why I dislike electronic computer gadgets generally is that they are obsolete so quickly.
So, anyway, thanks very much for your information.

I have three computers backing up onto the same Time Machine. The Hard drive of one has now failed, and I'd like to restore certain items (principally photographs) to one of the other two computers. How can I do this?

"You can also browse the original backup disk for past backups by using "Browse other Time Machine Disks"--to see this choice, hold the Option key then click the Time Machine menu in the Finder (to see the menu, "Show Time Machine status in the menu bar" must be selected in Time Machine preferences."

Do you mean the external hard drive is not mounted on the iMac desktop?
Check if Disk Utility sees the drive. Applications / Utilities / Disk Utility. If the external shows up in the left column, select it and click on Mount.
If it does show up this way, I recommend using DU to Repair Disk.

Using Mac Mini, Time Machine and External Hard Drives as a Backup Server

Hello...
I own a graphic design studio and have been looking for a long time to create/buy a no-thinker backup system for my macs. I have 4 workstations that I would like to backup to one central "server".
So what I was thinking was buying a Mac Mini, 3-4 external USB 2.0 Hard drives, external Blu-Ray burner and upgrade all our systems to OS 10.5. What I need to know is, will each work station with Time Machine on it back up across the network to a specific drive on the Mac Mini? If I have each workstation automatically mount one external across the network onto the desktop, will Time Machine recognize that hard drive as a legitimate drive to backup to?
Having the external Blu-Ray disc burner will give me the ability to burn data to a disc so I will have a way to take some of my information off-site. Since we are a graphic design studio, we use large amounts of disc space and regular DVD-R (4.6 gigs) is just not enough to back up some projects.
Can someone enlighten me, and tell me if this would work or not. It's the only way I can see me creating something that has enough space, will back up automatically across the network and allow me to make off-site copies of my data without spending $5,000.00.
Thanks for any comments you might have on this topic.

I'm a member of a freelance graphic artist team and have been scraping by with my MacMini and CS3. I recently obtained a used iMac (approx. 2 years old) and, instead of painstakingly transferring everything left on the Mini to the iMac, I wanted to know if it's possible to turn the MacMini into a pseudo external hard drive using the FW800 port.
I already had an external attached to the Mini and plan on using that as well, but I tend to hoarde information and run out of space really quickly. So keeping the mini around, preferably in a way that I can access it as an external through my iMac, would be perfect. I have very little experience with networking and don't have a wireless connection (yay modem cables!) so I don't quite know how to figure this out.
Has anyone done this? Would a FireWire 800 work? Would I need to set up a network between the two and use them as independently connected computers?

Look in the Utility folder which is located inside the Applications folder.
You don't want to do anything with the disk on a PC if you want it to work on the Mac. They both use different formats.

I entered Iphoto for my user and only photo up until 2012 were in the library. I thought the restore would do the incremental Time Machine backups too.....

Time Machine Damaged External Hard Drive?

hi,
okay, So I've had Leopard for about a week with no problems at all. I used my G-Tech G-drive (external 500gig) and it showed up on my desktop and worked perfectly fine with time machine. Yesterday, I went into time machine and the hard drive went from its resting state to into its high volume spinning, but time machine woudn't function at all, the stars moved but nothing could be clicked on, or exited from. after 15 minutes of trying to force quite (you can't get to it), i had to use the power button to shut off my mac. I turned it back on and there wasn't any problems, except now when my hard drive is plugged in it still spins normally, but the mac isn't recognizing it. Does anyone know what happened to my hard drive?

So it randomly started working again.
I restarted my computer for the 15th time, and turned it on once everything was up and running and it was recognized after about 5 minutes, so we shall see if it lasts.

Can I use my time capsule as a time machine and a hard drive

Hi all,
Can I use my time capsule as a time machine and a hard drive?
I don't want to store much on my imac, I would like to store it on the time capsule.
If this is possible, how do I do it?
Thanks, Crankyhead.

This is often asked.. and we always have the same answer. have you thought this through?
