QUESTION: MY Casablanca S4000Pro internal hard drive is 97% full. I used the HD Hard Drive Backup to backup all 30 projects into the External LaCie hard drive but the storyboards and scene bins are still full. What steps do I take to back up one project at a time and at the same time free up the space in to project?
ANSWER: My first comments won't really help you now, and likely won't be pleasing to hear... but it is strongly recommended not to exceed 90% of your hard drive capacity. Some folks won't even go above 85% to ensure enough data space to complete the projects you have in process.
Now onto to your answer:Now onto to your answer: There is no formal method for archiving (backing-up) just one entire project (both Scene Bin & Storyboard, audio, etc). You could use the Storyboard Archives (from the project Settings menu) but that only gives you the Storyboard, not any inserts, not the complete effects settings and only the top track of audio).
Some colleagues are using the Bogart HD Backup feature to backup just one or a few projects at a time onto an external HDD but there is not a means to do this with a hard drive as full as yours. If you had a new (2nd) external HDD... first, confirm that you have your nearly full hard drive successfully archived on what I will call HDD#1
What you would/could do is to delete all projects on your internal HD except one. Then archive this project/s onto the external HDD#2 with a different name (project name, etc). Then load back the full HDD from HDD#1 and delete all projects except a different project, back that up to HDD#2 with a different name, etc. After you have done this with each of your projects you would have all separate projects archived (backed up) with a different name... the full HDD with all 30 projects is actually what is being archived but since you only had one project in the internal HD that is what has been archived.
