Dear Pavel,

 

Thanks for quick response.

Exactly parallel option is there in version 9.3 but I can’t upgrade new version due to some concerns.

Could you suggest in 9.1 how may I fix it.

 

1. don't use it - you can use physical full backup with export transaction segments.

 

or

 

2. buy faster IO

If you can upgrade to a newer version, there is parallel pg dump.

 

Documentation - https://www.postgresql.org/docs/current/static/backup-dump.html

 

Related blog - http://paquier.xyz/postgresql-2/postgres-9-3-feature-highlight-parallel-pg_dump/

 

Which can give significant speed up depending on your machine's I/O capabilities.

Hi Expert,

 

I have a database having size around 1350 GB, created in PostgreSQL-9.1 in Linux platform.

I am using pg_dump to take backup which takes around 12 hours to complete.

Could you please suggest me how I can make my backup fast so that it complete in less hours?

 

Thanks in advance.
