Hello today i will tell you how to install PgBackRest Before reading this article, make sure you have set your ssh settings. This post was written for PostgreSQL 11 and PgBackRest 2.15 Setup Master settings First, let's install pgbackrest with the following command sudo apt-get install pgbackrest -y /etc/pgbackrest.conf let's open it, delete the contents and watch the following [global] repo1-host=xxx xxx xx xx repo1-host-user=postgres process-max=2 log-level-console=info log-level-file=debug [main_stanzamiz] pg1-path=/var/lib/postgresql/11/main pg1-port=5432 repo1-host:IP of the backup server repo1-host-user:The user of your backup server note: you could also create another user instead of postgres. In our installation, I used postgres because the postgres user came ready and we made the SSH settings accordingly. pg1-path:postgres cluster permission data folder You can give any name you want as main_stanzamiz stanza: configuration that includes the settings of a cluster such as backup, archiving repo: where the backup will be taken. can be a local or a remote machine Now, let's tell PostgreSQL to send WAL files to pgbackrest /etc/postgresql/11/main/postgresql.conf archive_mode = on archive_command = 'pgbackrest --stanza=main_stanzamiz archive-push %p' systemctl reload [email protected] sudo apt-get install pgbackrest -y /etc/pgbackrest.conf let's open it, delete the contents and watch the following [global] repo1-path=/var/lib/pgbackrest repo1-retention-full=2 repo1-retention-diff=2 process-max=2 log-level-console=info [main_stanzamiz] pg1-path=/var/lib/postgresql/11/main/ pg1-host=xxx.xxx.xx.xx pg1-host-user=postgres repo1-path: where to save backups on our backup server repo1-retention-full: limit of full backups, after this number the previous ones are deleted repo1-retention-diff: diff of the above pg1-path: data folder of your postgres cluster pg1-host: postgres cluster IP pg1-host-user: postgres Note: pg1-host-user must have read and write permissions to the cluster folder Now let's create the stanza. as a postgres user pgbackrest --stanza=main_stanzamiz check control with. You should get an output like INFO: check command end: completed successfully (2502ms) on the last line. Do the same check on the master server Now let's take our first backup. Backup is taken from backup/repo server Restore is done from master server Since we will take a backup, switch to the backup/repo server. pgbackrest --stanza=main_stanzamiz backup pgbackrest will take incremental backup by default. But since we do not have a full backup, it has to create a full backup at the first time. You can force a full backup with --type=full. You can also choose incr and diff.
