After an external Backup-Harddrive of mine made some Problems I really need to work out my archiving workflow and I have some questions.
LTO still seems to be the best and cost effective way for long time archival. The question is LTO-4 or LTO-5. The tape deck price difference is just a few hundred. LTO-5 tapes store 1.500GB whats nearly double of LTO-4 tapes but at more than double the price. But as long as you can write LTO-4 tapes with an LTO-5 deck I assume the 5 is worth the price difference?
So this would be an archival sollution for RAW files and finished Projects. But that is 'just' one copy.
While working on a project, having a backup of the RAW Data on LTO-Tape and storing Project files Online, while working with a redundant Disc Array like RAID 5, seems fine to me, or what is your workflow.
I'm mainly working on Music-Videos. I always deliver standart Formats, for TV and Web, but after a project is finished, payed and distributed the one thing I'm asked most of the time is to render out specific file Formats. I then just need to grab the final uncompressed render of the Clip and encode it to their wishes - of course they could do it by their own, but most clients don't know how and don't even want the big uncompressed file, but consider me to archive it and deliver further formats, something that's fine for me to do.
So I'm thinking about a cost effective way to store just the final uncompressed clips and be able to grab them fast and easy. And as I dont trust harddrives I was thinking about Bluray. Does anyone of you use Blueray for storage? A final Music video in 1080p is about 30 GB so it would fit a 50GB Bluray. What if a file is larger, like a shortfilm I made, where the final size is 150 GB? Am I able to store this one file to several Blurays?
Or are there any other cost effective possibilties I'm not aware of?
