P2 workflow – how to manage source files?

[Deleted User]

You’ll probably have the option of backing up, for example, DVCPRO-HD source files losslessly via Firewire to a DVCPRO-HD tape deck such as the model 1200, and archiving the tapes.

Or, if you capture all of the source footage to a computer HDD or RAID (even temporarily, just as a step in making a backup), you can then backup this data as you would other computer data: To data backup tape cartridges, DVD-R data disks, or new high-capacity DVD “HD” data disks (BluRay, whatever) when they become available, and so forth.

Backing up to one or more redundant HDDs could work as a temporary backup strategy, if you plan on later transferring this data to other more-stable media in the not too distant future.

All the best,

I’d go hard drives. They’re cheap enough these days to archive to- especially internal SATAs you can dock with. If you want something more expendable, you can go LTO, DLT or the like.

Hard drives are fine for short term storage, but are not a safe bet for long term archival storage. I asked Seagate Tech Support about what would happen if you stored a hard drive in a closet for 5 years, and then plugged it in to retreive data from it. They said it probably wouldn’t start up.

Hard Drives have moving parts in them, and like anything with moving parts, they require to be used so they don’t seize up. Your car won’t start if not turned on for 5 years either.

FWIW, I asked this of Seagate two weeks ago for this very reason – shooting with the Panasonic DVX200 and how to archive your original footage. Since we all know we’ll have to go back to our original footage sometime in the future …

Seriously? Who at Seagate would say this? Doesn’t speak too well for their company.

I’ve been thinking about this a lot recently. I think that what really makes sense is some form of tape backup. For instance you can get an LTO-3 drive that will store 400GB per tape for about $5,000. The tapes are about $120, which will store over 20 hours of DVCPROHD at 24 fps. For comparison, a 1200a with the firewire board is about $25,000, and the tapes are about $30/32 minutes. The nice thing about this kind of archival is that you have the option of restoring your project to exactly the point you left off — the time lines, the graphics, etc. and you never have to recapture video (which may have come from various formats that you may not even have the VTRs for.) With decent backup software you can restore individual clips as well (assuming you’ve created intelligible meta-data).

That’s where my head’s at, anyway — and not just for P2 I might add.

Any data storage technology is a candidate for backing up. DVCPRO-HD tape is probably the least desirable way to go, because you lose all metadata. Hard disks, Blu-ray or HD-DVD disks, even DVD-R disks (a regular DVD-R backs up a 4gb card easily, a dual-layer backs up an 8gb card).

But as Jesse said, a data tape backup system might be the most cost-efficient way to go. Perhaps a DLT or comparable system.

I think you’re all wrong.

This stuff is going to be the way to go.
…and look at this media. $1 per card for 30 gigs.

wonder when it’s shipping!

err yeah we talked about this a couple of weeks ago- maybe late 2006 or 2007. It’s sort of hard to work with vaporware.

Hi,

Keep in mind that in 60 frame HD 30GB is only 30 minutes, in 24P it would probabley hold a litte more than an hour. I think in the long run for archive you need to think about bigger numbers like several hundred gigs minimum, and on upto terrabytes.

Best,

Jan

[Noah Kadner] “Who at Seagate would say this? Doesn’t speak too well for their company.”

Or it does speak very well for the company. They are being honest.
Of course not all 5-years-on-the-shelf drives would not work, otherwise they couldn’t give 5 year warranty, but there might be something like 1% does not start.

I’m voting for optical archive. 50GB brd’s will be the cheapest, fastest and easiest way.
