archive_command 配置 POSTGRESQL 10.4

Question

Currently I have the following configuration for use archive_command in postgresql

postgres=# show archive_command;  
archive_command  
---------------------------------------------------------------- 
rsync -a %p barman@barman:/backup/primary_postgres/incoming/%f` 

In my Barman server I can see the WAL files but I want to know why this files are erased, I was waiting to have all the WAL files and then manually errase the WAL files for been able to recover in time (PITR) but I can see that the files are erased after some minutes

[root@barman incoming]# pwd
/backup/primary_postgres/incoming
[root@barman incoming]# ls -ltr
total 147456

Do you know why this behavior and how I can be able to keep more historical WAL files?

Answer 1

This is what "barman" does. Incoming WAL are put in "incoming". Then barman validates and catalogs them and moves them from "incoming" to "wals".

Why are you sticking your nose into barman's business like this? If you want your archive to be outside of barman's control, then don't put it under barman's control. Having your own home-grown tools and "barman" both trying to manage your system at the same time will end in disaster. Decide if you want to use barman, or not use barman.
