Have you worked with PgBarman or PgBackRest? Share your backup experience.

PgBarman and PgBackRest are tools for backing up and restoring PostgreSQL.

Experience with them includes:

• Setting up regular backups (full and incremental).
• Automating the backup process using cron or built-in schedulers.
• Managing backup storage, including deleting old backups and integrity checks.
• Restoring the database from backups in case of failures or data loss.

For example, with PgBackRest, you can configure a configuration file, specify backup directories and compression settings, and then run a backup with the command:

pgbackrest --stanza=mydb backup

It is important to regularly test restoration to ensure that backups are usable for recovery.
