Hi Kris, > 1) What is the current storage amount per user?
We don't measure this as we don't allow users to upload their own videos, we only do scheduled lecture recording and events at the moment. If a faculty member is teaching a course and in a lecture capture enabled room then it can be recorded for them regardless of how many other courses they might be teaching. > 2) What is the current retention policy - how long do files/videos > last? Is there an auto-destruction date or time? Is there the ability > to extend that? We keep the raw media that is captured by recording devices for at least 2 years unless the instructor asks for it to be destroyed before that. This time amount is an autodestruct, so they need to request that it be kept longer if they want it longer. We haven't offered the service for two years yet, but, my guess is that we'll keep data for users past this point only on a case by case basis, and that we will encourage users to export video to their local systems (in the case of a Department or College), or offer a minimal fee for the storage. This is pretty presumptuous on my part though. >3) Is anything done in terms of archiving past > videos/courses and if so any restore possibilities? >From the raw video we keep we can restore a video for student playback with 24-48 hour turn around time. We also keep videos in our playback tools for at least 30 days past the end of the course. We're considering at the moment what it would take to extend this (and plan to measure demand). Here are a couple of links to our published terms for faculty: http://www.usask.ca/its/services/e_learning/lecture-capture/frequently-asked-questions-faqs/index.php http://www.usask.ca/its/services/e_learning/lecture-capture/terms-of-service/index.php We do space estimates on a per course per semester basis. We have 13 weeks of courses at 3 hours per week. For engage we need 2.4GB/lecture, so this works out to roughly 100GB/course for storage. For working directories I think we're aiming for several hundred gigabytes, so that failures don't stop other lectures from processing. For archiving, believe it or not, it's actually less data. Roughly 1.5GB per lecture, so we use around 60 GB/course. We're doing a dozen courses/semester now, and thinking of doubling that next year. So we'll be using 6.5 terabytes of archive once the first lectures begin to expire from archives. Predicting doubled growth for three or so years of offering this service.
