Ensure base backups are configured and functional

中级别 1人工审核postgres

说明

A 'base backup' is a copy of the PRIMARY host's data cluster ($PGDATA) and is used to create STANDBY hosts and for Point In Time Recovery (PITR) mechanisms. Base backups should be copied across networks in a secure manner using an encrypted transport mechanism.
