Workflow in DV rack

Anyone have a good redundant workflow when using dvrack - you capture to one hard drive - but then how, and how often do you backup your data? And how do you do this in a foolproof way?

When shooting with P2 cards I copy to 2 hard drives and then backup to a dvd - what is an equivalent and safe workflow here?
 
On our feature, we record in sequences. Each sequence is a DVrack project.
At the end of a sequence, or the end of the day, whichever comes first, a copy of the folder with the DVrack project is made from HDD-1 to HDD-2 on set. At night, a copy is made from HDD-1 to HDD-3. So all media is kept in triple for redundancy.

Rule of thumb is that our set of 3 disks may never be in the same place at the same time. Two disks can be together( they must be, in order to copy), but not three. The third disk is always left at home. In this way, in a worst case scenario( lightning strike,...) all that is lost is 1 day of shooting. A raid system was considered at first, but rejected, because it is not lightning-proof.
 
That sounds reasonable - I was trying to figure out a way to incorporate dvds into the workflow . Like record to 4 gig cards and disk to somehow know when 4 gigs was used up.

Will the camera record to dvrack with out a p2 card - and if not do you just delete the card every so often?

It's still a good idea (provided it's not RAID0), because it reduces the chances of losing your data to mechanical problems. There are many portable, external hardware RAID1 enclosures available, they would make good choices for offloading / recording drives.
 
Eight+ months into it, with no apparent issues, I'm still finding $22 LTO-2 tapes to be a good substitute for that "third" hard drive. Initial investment was a used Dell (Quantum) PowerVault 110T deck on eBay ($750).

Makes no difference if I'm backing up a DV Rack project, MXF, whatever . . . it's all "ones and zeros". Apparently there are not a great number of us going this route?

DV-rack works without a P2 card, but you have to start and stop recording on the laptop itself. With a P2 card inserted, DV-rack works in slave-recording; it starts recording automatically when you start recording on the camera to a card.

In the beginning, when DV-rackHD was still in beta, we used the P2 cards together with dv-rack, to be on the save side. Now, we record everything to DV-rack, and only use the cards for some special shots.

I'm still very reluctant to put all eggs into one raid basket. I've seen raid-1 and raid-5 systems go tits over ass. Also, what if you're in a car crash, the raidbox falls into a bucket of water,...

It's a good solution for large storage on set, but do make ( at least one) secondary copy, and keep it in a secure off-site location. Your secondary copy could be a identical raidbox, or LTO drives like Dregenthal suggests.
 
All I'm saying is that instead of having three drives in separate locations, I'd have more faith in three RAID1 drives in separate locations.
