Hi Marco,
Sorry for delay. I just want to see what's gonna happen in next backup process. We use archiving via archive_command that includes rsync. I checked log file and I did not faced any error about archive_command or rsync process. Current backup still continuous. Backup process takes long time and I'm gonna look at barman list-backup command and I'll share if still continued this problem.
Thank you for your helps. 
Regards,Gunce

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

Hello,

There are some cron which execute insert, update statement daily. It's not possible nothing happened after previous backup. So, do you have another idea about that?

Regards,
Gunce

        Hi all,

        We use Barman for backup. I checked latest backup as to whether
        having latest backup is success and I saw WAL size is 0 B.

        -bash-4.1$ barman list-backup dbalpha
        dbalpha 20171127T190002 - Tue Nov 28 09:43:40 2017 - Size: 326.0
        GiB - WAL Size: 0 B ....

        I think it's not normal. Any help would be appreciated.

    ​This is quite normal scenario, I suspect as not many transactions
    have happened since its previous backup was taken which resulted in
    WAL size to 0 B​
