# RDBMS

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

Doltgres supports [backups](https://docs.doltgres.com/concepts/rdbms/backups). There are two options for backups:[remotes](https://docs.doltgres.com/concepts/git/remotes) or [backups](https://docs.doltgres.com/concepts/rdbms/backups). 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](https://docs.doltgres.com/reference/version-control/dolt-sql-functions#doltbackup).

Doltgres leverages Git-style [remotes](https://docs.doltgres.com/concepts/git/remotes) 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".
