# RDBMS

Doltgres can be used as a Relational Database Management System or RDBMS. Doltgres ships with [a\
Postgres compatible server](/concepts/rdbms/server.md) built in, accessed via the `doltgres`\
command.

Doltgres supports [backups](/concepts/rdbms/backups.md). There are two options for backups:[remotes](/concepts/git/remotes.md) or [backups](/concepts/rdbms/backups.md). Pushing to a remote only backs up committed\
changes. Using `dolt backup` backs up uncommitted changes as well. Backups are accessed via the[dolt\_backup() function](/reference/version-control/dolt-sql-functions.md#doltbackup).

Doltgres leverages Git-style [remotes](/concepts/git/remotes.md) to facilitate replication. The master and\
replicas configure the same remote. On the master, you configure "push on write" and on the replicas\
you configure "pull on read".
