I was just addressing the working copy, not the backups. Moving things to the new working system would allow me to retire my old working copies to backup status, and since they're full, they won't be in use and can go offsite. But, you're right my working copies, and my two backup copies of my last five years of photography are all currently in the same building, with the negatives and prints of my previous 35 years of photography, and I expect the same thing would happen to the drives as to the negatives. > >> My gut feeling is that the right way to do this is some sort of external >> drive that I can share between the two machines for storing all the RAW >> files.

Main computer: 4 drive RAID 10 array, two cold drives ready the four drive RAID 10 array is in the computer? This is not a feasible, or even possible, solution with an iMac or a laptop.

I guess you can't do film to film contact prints. I suspect that the solution that I'll end up with for working on multiple machines will be just to put my working files on their own external hard drive that I can easily transfer from machine to machine. > > -- > Doug "Lefty" Franklin > NutDriver Racing > http://NutDriver.org > Facebook "NutDriver Racing" > Sponsored by Murphy > > > -- > PDML Pentax-Discuss Mail List > PDML@pdml.net > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
