Following on from this post...

I have a backup generated by pg_basebackup regularly, I would update it through the WAL files.

What is the best way to do it?

See the documentation on point-in-time recovery and WAL archiving for how to manage this.

Short version:

  • Set archive_mode = on in master
  • Set an archive_command in master that stores the WAL archives in a location accessible to the replica
  • Create the replica from a pg_basebackup
  • Create a recovery.conf on the replica that sets a restore_command to fetch the archived WAL. You may also want to set a recovery_target_time if you wish to stop replay at a certain point.
  • Start the replica and let it replay WAL

You may find tools like pgbarman useful as well.

  • There is a tool like pgbarman for windows? – Marcos Sep 15 '15 at 22:49
  • Not that I know of, not on Windows. Most of the PostgreSQL infrastructure continues to focus more on Linux and Mac OS X. Support for Windows may be added to a future version of Barman, I know they're talking about it. In the mean time you'll have to use your own scripts/tools. WAL-E might work on Windows, though, I haven't checked. – Craig Ringer Sep 15 '15 at 22:50
  • Is there a script I can do the restoration? – Marcos Nov 4 '15 at 15:26
