A computer-implemented method for maintaining remote backups of reverse-incremental backup datasets may include (1) receiving a request to replicate a reverse-incremental backup dataset of a data source (e.g., a local full backup of the data source and/or at least one reverse incremental backup of the data source) from a primary storage system to a secondary storage system and (2) generating, in response to receiving the request, a forward-incremental backup dataset of the data source (e.g., a remote full backup of the data source and/or at least one forward incremental backup of the data source) on the secondary storage system based at least in part on the reverse-incremental backup dataset. Various other methods, systems, and computer-readable media are also disclosed.
