Regarding "Point-in-time Recovery" feature

[Saurabh Gupta A <saurabh.a.gupta@xxxxxxxxxxxx>]

 

Hello,

Has anybody used online backup feature of postgreSQL? In fact precise postgreSQL term is called: "Point-in-time Recovery" (PITR)
This means enabling following additional options in config:
---
archive_command = on
archive_command = 'cp %p /usr/local/pgsql/pgDataPITR/wals/%f' # This is only example path
---

 

If yes then may I know how it is used and how it impacts database performance?
