Incremental backups suggest the need to backup WAL archives. See https://www.postgresql.org/docs/9.2/continuous-archiving.html pgbackrest looks very cool but we haven't used it. A very simple solution could be just to dump the database daily with pg_dump, if you have the space and machine capacity to do it. Depending on what you are storing, you can achieve good compression with this, and it is a great way of having a simple file from which to restore a database. Our ~200GB cluster resolves to under 10GB of pg_dump files, although 18TB is a whole different order of size. Rory
