Re: Backup failure Postgres

Hi Torsten,

I have tried by increasing the max_standby_streaming_delay but I'm facing
lag issues on the replica server.

When i increase the max_standby_streaming_delay even if a query runs for 2
minutes I'm facing lag issues for 2 minutes.

Please suggest here.
Data size is 3TB
