POLL: How are you archiving?

[Mark Palmos]

Hi Bill
Thanks for the heads up,
it looks like its only 2x blue ray double layer, the FastMac is 4x – which is quite a difference when you have lots to copy.
Cheers
Mark.

Hi there Bob,

I think the problem with CD and DVD isnt that they fail easily, they dont, (drop a hard drive on concrete, and drop a CD on concrete, see which fails more easility!)

I think the problem is that when CD came out, there was this spin about how hardy they are compared to Vinyl, you can scratch them and they still sound perfect etc.

Of my 1500 CD’s in my music library, not a single one has failed, and the oldest, Ry Cooder’s Jazz, is 22 years old and has been played dozens of times.

If one looks after DVD/CD/BluRay disks, they will certainly last longer than hard disks. Never put them on tables or on each other, treat them like Vinyl and they will last and last HD just plain dont.

Speed is good! Walter mentions in this thread he uses a FastMac internal and a standalone 2-burner replicator.

[Bob Cole] “I haven’t kept count, but I’d estimate about 1/25 of my data DVDs fail.”

but bob, a failed burn is completely different from a successfully burned disk which fails after some time. Have you had ANY of those (given they are scratch free, fingerprint free, and have not been left on the car dashboard in the arizona sun for a year!)

Yes I have. I wasn’t counting failed burns. Mark, this doesn’t happen often, but just one or two failed DVDs on which you were relying can be quite disastrous. But the main reason I’m down on DVDs is their low capacity. And it’s another reason for higher-capacity formats like tape: if it’s easier to make backups, it will be easier to make TWO backups.

I don’t know the science behind this, but the only DVDs that fail are the ones which

(1) hold data you need; and
(2) are the only place you’ve stored the data you need.

MacPro 2 x 3GHz dualcore; 10 GB 667MHz
Kona LHe
Sony HDV Z1
Sony HDV M25U
HD-Connect MI
Betacam UVW1800
DVCPro AJ-D650

lol
yep
but i reck a blu-ray disk, verified after the burn and looked after (ie, not in the hands of your apprentice nephew) should last for yonks, well at least that is my hope and expectation!

Hi there,
I’m just getting into the backup (archiving) scenerio with Blue Ray (LaCie d2Blue Ray) using Toast 8.
I’m wondering if I should I use rewritable DVD’s and dynamic writing – using the DVD’s like a HD – or burn write once DVD’s and using Toast to bring the files back into the system?
Pro’s – Con’s ?
Thanks

my feeling is to use write once and to see te bluray disks as your “tapes” for archiving. Rewritable disks are only useful if you a/ dont fill a disk each time and you want to add little bits at a time or b/ dont want to permanently keep the media.

both of these are not really valid because
a/ 25gb is not much when it comes to video media, so its more a case of having a few disks per project than of uisng the same disk for many projects
b/ you wouldnt need the bluray disks if you were going to throw away the media anyway.

so get the write once.

the only advantage i see in the RW disks is if your burn fails for sme reason and you can try again.
