Thread: Pgbackrest specifying the default DB necessary/correct way ?
List,
I have configured the pgbackrest on a live DB server and a Repo Server. ( EPAS 16, RHEL 9.4 and Pgbackrest 2.52.1 )
On DB Server I have
##############################
[root@db1 ~]# cd
[root@db1 ~]# cat /etc/pgbackrest/pgbackrest.conf
[Demo_Repo]
pg1-path=/data/edb/as16/data
pg1-port=5444
pg1-user=enterprisedb
pg-version-force=16
pg1-database=edb ## Query 1.
[global]
repo1-host=10.255.0.40
repo1-host-user=postgres

spool-path=/var/spool/pgbackrest

## Query 1:
In this DB server I have other databases than the default "edb" database. Specifying the above line as pg1-database=edb // I am not sure this line is necessary or not ?
( I am just learning and exploring PgbackRest) found online some reference configurations so using like this )
pg1-database=edb // specifying like this, will it block other databases on this server to get backed up ? IF yes how can I overcome this ?
I want all databases on this server to be backed up to the remote repository.
It is a production server and I can't perform a trial and error method here to understand how it works.
Please shed some light on this .
Thanks ,
Krishane

The pgbackrest process needs to connect to the database, which means it needs a user and database. You need this variable if you do not have the default database, "postgres". If you have a database named postgres, you can leave this out. Otherwise, yes, it is necessary.

pgBackRest works on a cluster level, so *all* the databases are backed up. Indeed, it is not possible to only backup some of the databases. It's the whole cluster.

Probably best to stick to the official docs; this section in particular is worth a read:
Cheers,
Greg
Very helpful.
