SLOW BURN SPEED for DUAL LAYER B/U
Hello:
I’ve got an Aluminum 1.67 Ghz PowerBook, bought specifically for downloading footage from P2 cards. I was planning on backing up the MXF files to Dual-layer DVD+R disks. But the burn speed is only 2.4 x on this machine. I was hoping to do this on location, but we’re talking about 40 minutes for a full P2 card.
Curious as to others’ strategies to protect their data. Any real-world experience/advice welcome.
Best, JIM.

Back up to a second hard disk. You should be able to execute copies to both hard disks simultaneously with little to no impact on speed (i.e., if it takes 4 minutes to copy a 4GB card to one drive, it should take like 4:15 to copy that same card simultaneously to two drives).

Hi Barry:
Thanks for your note. I will be backing up on two drives on set. I guess my question was more one for archival purposes. I think I may just put a faster DVD drive in my G5 tower and burn the disks at my office. Then I can give the production a binder full of disks (that have a one-to-one relationship to the original P2 cards) at the end of the shoot, to keep off premises.
Still curious what other workflows folks are using. Anyone else care to chime in?
Best, JIM.

there are no faster DL drives or media at this time. 2.4x is max.

I’m with you, Jim. Archiving is one of the most challenging parts of the P2 workflow. I’ve got 200 8 GB files for one project; backing up to DVD would take a lifetime at current speeds. My current strategy is to back up to two Lacie Rugged drives via my Powerbook in the field; then dump files to two OWC 500 GB drives at end of day. It makes for a long day, but allows me to review footage and keep my catalog up to date. Recently I’ve added the cost of a set of drives to budgets so I can give them to the client at the end of the project. I look forward to the next generation of DL burners.

Hey Gerret:
Thanks for your response. I should have about 100 P2 cards full by the end of the shoot. I’m committed to burning them on DVD (as well as backing up the MXF files to a drive array here at the office) as an alternative to hard drives in my backup strategy.
I know it’s going to take time to do it, but at least it can cook away without me having to watch it all the time. I read that the Pioneer drive says it can burn DL up to 10 X speed, but of course that’s a tower drive — not portable…and that’s also assuming Toast 8 and OSX can work properly with that hardware.
As for an extra set of drives for the client, I’m doing the same thing. Hard drives are turning out to be one of the most cost/time-effective ways of handling lots of data.
Thanks again for the input. Best of luck with your projects.
JIM.

Jim,
Yes, I think we now own about 25 500 GB drives. We’ve been buying OWC because they’re both dependable–so far–and light. We send them to freelance editors all over the country, and now will be sending them to clients with all their MXF files.There is a solution to archiving that sounds pretty good in every way except cost: the Quantum SDLT 600A. Not sure, but I think it runs about $6k, which means we’re not buying it today.
Backing up to DL disk means you won’t be buying 16GB P2 cards, I guess.
Good luck,
Gerret
