Hmmm…sounds like we are all talking about backing up the files. We backup the project files, graphics and pre-renders etc, including most but not all of the actual media to a hard drive. We also back up the project files without the big media files to a DVD. If it is short form, we include a DVD if we authored one for the project in the backups. This way we have two copies of both critical project files. And since I don’t really trust hard drives for critical backups, we make the DVD data backups too.
We use hot swappable 250 gig SATA drives. We might move to the 500s soon. Also, we are primarily a SD shop so we don’t have a ton of HD rez footage to backup, and we use DVCPro50 and DVCPro HD codecs for our projects.
We also archive the final edited program to DVCAM tape. Many times we can simply do a 5 minute upload of the show to make a change etc. Rarely does it require a full media restore.
We do not charge for backups per se but we do charge for time restoring the project and add about a half hour of our “Prep Time” rate to every invoice for doing the backups and covering media costs. I would rather roll items like backups into our service rates than line-iteming them on the invoice.
