Re: Backup taking long time !!!

I hope you realise that 9.1 is EOLed - http://blog.2ndquadrant.com/postgresql-9-1-end-of-life/
Which means that the version that you are using will not receive any updates which includes critical updates to performance and security.

If I were you, I would work on the issues that stops me from upgrading, but that is my opinion.

As pavel said, you could use a physical backup instead of pg dump.

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.
