systemd unit files for PostgreSQL on Debian/Ubuntu -------------------------------------------------- Each cluster is run as a separate service, called postgresql@version-cluster. pg_ctlcluster is invoked with --skip-systemctl-redirect. Logging still goes to /var/log/postgresql. There is a parent service called postgresql.service, that starts/stops/restarts/ reloads all individual services that are configured as "auto" in /etc/postgresql/*/*/start.conf. The link between start.conf and postgresql.service is established by postgresql-generator, which creates symlinks in /run/systemd/generator/postgresql.service.wants/. Backup ------ Two backup mechanisms are being offered as systemd services: basebackups capable of point in time recovery (PITR, the preferred method), and SQL-level dumps. pg_basebackup@version-cluster.service pg_basebackup@version-cluster.timer Weekly basebackup in /var/backups/postgresql/version/cluster. By default, 3 copies are being kept. To enable, run systemctl enable --now pg_basebackup@version-cluster.timer systemctl start pg_basebackup@version-cluster.service pg_receivewal@version-cluster.service WAL archival to be used with pg_basebackup@.service for PITR. To enable, run systemctl enable --now pg_basebackup@version-cluster.timer pg_receivewal@version-cluster.service systemctl start pg_basebackup@version-cluster.service pg_dump@version-cluster.service pg_dump@version-cluster.timer Weekly SQL dump in /var/backups/postgresql/version/cluster. By default, 3 copies are being kept. To enable, run systemctl enable --now pg_dump@version-cluster.timer systemctl start pg_dump@version-cluster.service The mechanisms provided are meant to be used with low to medium size databases. For larger databases, or databases with high write volume, we advise to use a full-size backup solution such as pgbackrest or barman. -- Christoph Berg <myon@debian.org> Mon, 08 Mar 2021 13:45:26 +0100
