This overlaps with ideas like store-and-forward, delay-tolerant networking, and the Interplanetary Internet. I've been writing local-first digital archives software. Our system uses git to store collection metadata and git-annex to manage binaries. It was originally designed to be used to allow partner sites with very low connectivity to contribute archival-quality video to a distributed archive. Data can be synced over the network or via physical storage sent in the mail. Using Git/git-annex for this system has advantages for archival preservation. Copies can be located in geographically diverse locations and synced as necessary. The Git log's use of cryptographic hashes also makes data tamper-evident.
