Hi-yah, I teach at a local technical college.
I want to put all our educational VHS videos, Power Point presentations, DVD videos and other educational digital media on a 1 TB HD for teachers to access via their laptops for class presentations.
This is how I was thinking of doing it:
Two - SATA2 1TB HD’s
Two - HD Enclosures
One - Power bar
One - UPS
One - USB Hub
Have two main directories (or equal sized partitions) on HD #1 labeled “S” & “P”. “S” for shared and “P” for protected. They would contain the identical data but only the “S” portion would be accessed by the teachers. The “P“ portion would contain the identical data as loaded onto “S”, but should part or all of “S” be deleted then “P” would still be safe.
Whomever monitors the HD’s would, when loading any new media files, load them onto the “S” side of HD #1 and the “P” side of HD #1 at the same instance, as well as (if possible) keep a master CD / DVD / VHS copy stored in a safe place.
The HD monitor would also then periodically backup the “P” side of HD#1 to HD#2.
I don't think RAID will be a good idea in this case, as what happens to one drive would automatically happen to the other, so there would be no longterm redundancy.
Maybe there is a better/simpler way or more of an all-in-one way? Maybe password protecting the drives and using read only formatting and not splitting up HD#1 into "S" & "P"?
