Re: PG_Base Backup take 8 to 9Hrs

Please use a third party backup solution that provides faster and more flexible backup alternatives than the built in, pg_basebackup(), which is not usefult for large databases.
pgbackrest (full, differential, and incremental)
barman (full and incremental)

We are using Postgres -11 version and current PG DB size is 450 GB .

Archive log enable in Database and we are running Full PG_Base backup and it will take 8 to 9 Hrs to complete the backup ,

Please suggest  how to reduce the full DB backup time.

Use storage snapshots, faster disks, faster Ethernet adapters and backup software that supports deduplication. You are asking the list to architect your backup solution. For that, some more information is needed: what kind of machine are you using, what OS, how much memory, what kind of storage is your cluster running on, what kind of storage are you backing it up to, how is the backup storage connected (FC/AL, Ethernet, local SATA drives), is there any degree of parallelism and things of that nature. In the absence of that information, I can only recommend attempting with the --run-faster switch to pg_basebackup. You may also try using the Force.
