Обсуждение: How to reduce pg_dump backup time

Dear Team,

 

I am using PostgreSQL 9.1 on Redhat Linux on my Production environment. My database size is 680 GB and it take 7 hour for completion the pg_dump backup.

 

I want that my pg_dump backup should be fast and take less time.

 

In PostgresQL 9.3 there is “ -j njobs” option is available for fast pg_dump backup.

 

There is any way, that I will use “ -j njobs” option in “PostgreSQL 9.1 “ so that my backup is completed in less time or any other way in ”PostgreSQL 9.1” to take the backup fast. Kindly suggest?

 

 

[root]# lsb_release –a

In addition to Scott's suggestions have you looked at replication?:

Basically, continuous backup.
