Hi!
I have 3 node postgres cluster with repmgr and pgpool.
Pgbackrest is configed like this
We use pgbackrest with this config
=======================================
[global]
backup-standby=y
repo1-path=/postgresql/backup
repo1-retention-full=2
start-fast=y
[PG]
pg1-path=/postgresql/data
pg2-host=node2
pg2-host-user=postgres
pg2-path=/postgresql/data
pg3-host=node3
pg3-host-user=postgres
pg3-path=/postgresql/data
=================================================
I run the backuplike this
/usr/bin/pgbackrest --log-level-console=detail --stanza=PG --type=full
backup
The backup of 50GB took 40 min.
It is not a network issue. I tested to transfer 2GB between two host and it
took 4 sec.
I think backup-standby=y slows down the backup out of all minds.
