Re: Barman WAL size issue

Hi,

which wal method are you using? Wal Streaming or archiving by using 
archive_command?

In case of streaming, you could check if receive-wal process is running 
on the backup host and connected to the barman replication slot on the 
postgresql server.

In the other case, check your postgresql logfile if you have errors 
about the archiving.


Greetings,
Marco
