Remus (differential backup tool)

Remus is a tool used to create differential backups, primarily for PostgreSQL databases. It tracks and saves only the changes made since the last full backup, making the process faster and saving storage space. When restoring, it combines the latest full backup with the most recent differential backup to bring the database to current state. This approach helps ensure data safety while minimizing backup time and resource use, making it efficient for ongoing database management and disaster recovery plans.
