I'm looking for a backup solution for a specific use case. If none exists, then I'm tempted to make one.

I have a large and growing collection of video files. On my workstation I have a fairly large disk in RAID5, consisting of a few 2TB disks, which is easily expandable. These files are never changed. If I need to edit one, then I create a new file. I use hotswapable 2.5" harddisks for backup, which so far I've done manually. It works, but I'm afraid of doing anything wrong. I might forget to copy a file, mislabel a disk, etc.

I would like a solution that watches the video files on my workstation, automatically copies new files to the current backup disk and presents me with an overview of which backup disk contains which files, descriptions, dates and where those disks are physically stored. It would be nice if I could just insert an unformatted disk and it would be formatted, labeled and tracked automatically. When the free space of a backup disk reaches a certain level, I should be notified so that I can store it safely and replace it with a new one. Each backup disk should contain a copy of the current database and thumbnails for the videofiles contained on this disk.

For restore, I should be able to simply provide a root directory where the hierarchy should be recreated and it would then tell me to "insert disk x" -- like installing Windows 95 from floppies.

Does anyone know of a free backup solution that fits this profile, or should I go ahead and make one?
