postgresql - Postgres replication + incremental backup -

-



i'm using postgresql 9.6.

is possible have replication , incremental backup on same setup

i have high availability setup. on main site have 2 servers replication between them , pgpool handle failover in case primary server goes down.

i have remote site geographical redundancy. site active if main site no longer functioning. remote site not need updated in real-time. therefore, if saves resources thought having incremental backup , restore main site remote site. in other words main site primary server replicate data main site secondary server. in addition generate incremental backup , backup restored on remote site.

from answer understood possible have both replication , incremental backup. however, solution better (resource consumption, reliability etc.) have replication both main secondary server , remote site server?

yes, can have pitr , streaming replication in use @ same time. streaming replication can fall restoring wal archive if loses direct connectivity master too.

lots more detail in manual. it's hard more specific rather open , vague question - what, exactly, mean "incremental backup"? etc.
