We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

These formats are generally not very compressible by general purpose compression algorithms, as they are already compressed formats themselves, each with a compression algorithm specially tailored to their content type.

Tar.

Mostly not joking here -- the image and video formats you list are already heavily compressed. You'll be lucky to get even 1% compression from any format, so you might as well just package them up in an uncompressed archive format.
