As for storage, as long as you have "Backup in Depth", then any collection of external disks is fine. I've got Drobos, iomega, G-Drive, and a bunch of misc generic drive enclosures with commodity disks inside. It is the "Backup in Depth" that counts, more than what you use as storage devices.
I read everything. I'm like you Doug. However, backing up only home pics/vids of my 6yr old daughter and my docs/spreadsheets (the music hasnt even made it off my old Dell P4 desktop HDs onto this MBP yet; my only concern right now is memories) -at this point is all I need.
Chronology & subsequent Quandry: So i get my first Mac, and phase 1 ensues: eventually e'Buy' a USB 2.0 IDE enclosure (rocketfish - PITA HW-wise, but completely reliable). I throw a 200 Gig 3.5" 40-pin in there, cable select, mounts no problem, format it Mac OS X (journaled), set up Time Machine and I'm done and rolling in no time (lovin' the MAC baby! concise & efficient is how I like it now. Little bro was right; we both used to build/tinker w/ PCs, now we just get stuff DONE!)
Phase 2 is where I'm hung up; and from the way I read your answer, and giventhat it looks like the methodS you use are somewhat similar to my plan(s), you might be the right guy that I'd want to ask...
Anyway, want to take IDE to mom & Dad's 7 miles away (I have another 5 EIDE's the same capacity so I'll cycle them obviously, and I'm taking for granted if my house catches fire (MBP -AND- attached external burn up -that there will be a definite loss of whatever pics/video are taken in between -I'm fine w/ that right now)......so........I'm at the dreaded BestBuy last week and they got Seagate 500G USB 2.0 externals (no power supply needed; & very small) -for $59.99. The 320G version of the SAME drive is $69.00 (sales guy states excessive inventory prob the reason. makes perfect sense to me. brother who worked there 6 yrs agrees); so obviously I buy it.
Long story short, I mount it fine, format it from NTFS to the same as above, and it won't come up in Time Machine now. Therein lies my dilemma. I understand why only one disk (as far as Snow Leopard OS programming logic), but there are too many sketchy work-arounds out there. So, I wanted to pick somebody's brain -that actually knows what they're talking about.
FWIW, when u open up TM and click "Select Disk...", it leaves room in the window [for more drives] that would lead one (me) to believe that backing up data this way (two separate, physical locations -old school, I know) -would be possible.
That's my excuse at least...
TIA for any direction you can provide Doug.
> ... format it from NTFS to the same as above, and it won't come up in Time Machine now
TimeMachine is not going to like NTFS. There are specific features in HFS+ that TimeMachine wants and depends on that are not in NTFS.
If your parent's system is also on the net, then maybe you could use "CrashPlan" to backup your stuff over the net. As long as you are using your own hardware and storage, CrashPlan is free to use.
You can also format your drives as HFS+, and then just store them at your parents, without attempting to connect them to a PC (there is Windows software that can read HFS+, but if having the disks at your parents is just to protect against loss at your house, then it is not necessary they be readable by the PC, just available should you need them).
Thanks Bob. After re-reading my post I see I didn't write that very sensibly. I even read it myself and it sounded like I was saying I formatted TO NTFS..... What I was in fact trying to say is that I formatted FROM NTFS (the Seagate 500 Gig came pre-formatted that way) ------TO: Mac OS X (Journaled). So it is definitely formatted Mac-style now. The problem is that Time Machine will only see one drive at a time. And that is what I'm trying to find a work-around for.
To answer your other question, no, I do not need to access the EIDE drive at my parents' house. It will be sitting on a shelf there in an anti-static bag just in case I have a fire at MY house. The only other time it would be touched [ideally], would be if/when I replace it with another 200 Gig EIDE HD that I'd periodically run through Time Machine and take over there as an updated 'fail-safe'.
For replies' purpose, let's hypothetically assume that my computer is stand-alone, not connected to the internet or any network.....and that I have no money for any additional hardware or software...
Can it be done?
First. My secondary (in depth) backups are not using TimeMachine. I use a disk cloning backup. Carbon Copy Cloner is highly respected and free, or you can make full disk clones using SuperDuper for free (SuperDuper wants the shareware fee if you wish to enable incremental backups). I happen to use SuperDuper, but only because I started using it before CCC reached its current level of goodness.
And I think for a disk you are taking to your parent's house, a clone of your system would be a good thing. And that would give you 2 separate backup methods so that a flaw in one, should not affect the other.
TimeMachine backup at home which gives you hourly incremental's so you can recover Oops! files, and a disk clone stored periodically at your parents. You could have the TimeMachine disk and the "Current" clone disk attached to your Mac with the clone backup (CCC) doing automatically nightly incremental updates to keep the clone in sync. Then you detach the disk when going to your parent's house taking the clone disk with you. When you return, you bring the oldest clone disk from your parents back, and hook it up to your Mac where you start cloning again.
Having said the above. I do not think TimeMachine will automatically use more than a single disk. I think if you go searching with Google, or specifically at MacOSXHints.com you may find scripts that will switch the disk TimeMachine backs up to.
I am also fairly sure you can use System Preferences -> TimeMaching -> Select disk to switch the disk TimeMachine is using at the moment. But personally I would just use the one TimeMachine disk and use a cloning backup up utility for your off-site backup storage.
By the way. The backup methods I use on my iMac are
TimeMachine to an external disk
SuperDuper to an external disk
rsync of selected key files to an external disk
At work I depend on the hourly guard rounds to detect any serious issues, plus most of my work related content is hosted on servers with corporate backup 2,000 miles away in a server farm.
As for my MacBook which goes with me to and from work.
SuperDuper backup to a Disk Utility Sparse Image hosted on my iMac at work
The .sparseimage is copied to yet another external disk on my iMac
rsync of selected key files are copied from my MacBook to yet another external disk on my iMac
(all together my iMac has about 8TB of storage at work)
If I could get corporate to give me a ton of storage on that server farm 2,000 files away, I would push an iMac backup to it, however, I actually use rsync to backup my work kept on the server farm to my iMac, just be cause I'm paranoid and do not want to loose any of my work because of an Oops by the IT guys maintaining the server farm (another reason I have so much storage on my iMac :-) )
