This is correct. My main reason for compression was to squeeze a little more mustard in the jar. I just did a test on a dozen or so videos. Uncompressed the videos was 214,931,665. Compressed it is 200,878,554. It's a little saved but other videos may not compress that much. Just depends. Even with that little savings, compression really isn't much of a solution especially since I do not want any loss in data. Given my weird way of doing backups, rsync may be the best option. Plus, easier to restore from as well since it just requires a copy command, any of them will do. Looks like bigger hard drives is the best idea for now. I really need a proper backup plan tho. I just wish a NAS would fit in my fire safe. ;-) Dale :-) :-)
