Once you have pg_probackup3 installed, complete the following setup:
Initialize the backup catalog.
Add a new backup instance to the backup catalog.
Configure the database cluster to enable pg_probackup3 backups.
Optionally, configure SSH for running pg_probackup3 operations in the remote mode.
Optionally, configure S3 for running pg_probackup3 connected to the S3 storage.
pg_probackup3 stores all WAL and backup files in the corresponding subdirectories of the backup catalog.
Before initializing the backup catalog, make sure the following prerequisites are fulfilled:
pg_probackup3 is connected to the Postgres Pro server.
The user launching pg_probackup3
has full access to
the backup_dir directory.
To initialize the backup catalog, run the following command:
pg_probackup3 init -B backup_dir
where backup_dir is the path to the backup
catalog. If the backup_dir already exists,
it must be empty. Otherwise, pg_probackup3
returns an error.
pg_probackup3 creates the
backup_dir backup catalog, with the following
subdirectories:
wal/ — directory for WAL files.
backups/ — directory for backup files.
Once the backup catalog is initialized, you can add a new backup instance.
