Archive SD DV50 PAL to tape - DV or BetaSP?

Up until now all our project are shot using P2, DV50 PAL widescreen.

The projects have been exported to disk and to DVCAM.

Since we have an AJA IoHD, I figure BetacamSP might perhaps be a better tape format? On the con side, the tapes are HUGE, compared to the DVCAM tapes... The DVCAM tapes, on the other hand are digital, but only DV25.

Should I stick with DVCAM or move to Betacam SP? (Or even both??)

neither!

Diigbeta would be the best

yes, if you go to DV, it's ones & zeros so no re-compression at all,
BUT
you are tailing about ARCHIVE, and the Digibeta tapes will probably last longer.
because they are huge, and not so fragile.

How about backing all of your P2 material to hard drives and export a copy of your finished product and back that up to HD also. Better quality and much cheaper than Digibeta all around.

Yup, make a digital master, back all up onto external USB drives, redundancy for protection.

a drive won't be guaranteed to last more than a few years.
Tape can last 30 if stored properly.

Tape may last 30 years... but will the PLAYER?

I am a fan of BluRay for archiving, myself. Easy to dub, easy to mail, wear-resistant, cheap to buy and store. Can play using game system, set-top device or computer drive.

We stopped backing up to "Tape Masters" a few years ago.
Redundant hard drives, spin em up every 6 months.
Yes drives fail, so does everything else at some point.
Having more then one copy protects you from loss.

If you want tape archives, why not use tape cameras? Why did you shoot digital if you wanted tape?

Want to archive to tape? Invest in LTO technology. When you shoot tapeless, it's best to archive the digital masters. I archive to two hard drives (basically a manual Raid 1), and spin them up occasionally.

BetaSP would be a step down from DV50. I remember an article a number of years ago by Adam Wilt where he discussed how BSP and DV25 were basically the same in terms of image quality. And that's to the power of the internet here is a synopsis of said article, http://www.adamwilt.com/DV-Beta.html

Just to echo what others have said, if you have the budget go with LTO. If not, go with mirrored HDDs.

Shane,

As always, you're right on spot. Sure there's no really need for archiving on tape since we shoot P2. I guess I'm still in those days where we shot on BetacamSP, captured using the Sony DSR-45P and ended up on DVCAM tapes. The deck still works (as does our UVW-1800P) so I thought I could just put things on tape as well.

The LTO is quite expensive. Having used LaCie disks and later 2,5" disks with enclosures from OWC (that caused us a lot of trouble) we now shifted to use RAID-1 enclosures. Sure, they are big (and noisy) but when you're finished you have two disk to put on the self.

Put them back and spin them up every six month, and I believe you're quite safe.

But I'll look into the LTO option. Do you have any suggestions on hardware/software?
