20220221-Clarification regarding PostgeSQL DB backup

От

Hi Team,                

 

We have used PG_DUMP to take backup of particular database from the PostgreSQL Server. It takes too long to restore the databases , which has  Half Billion records (almost 8 Hour)

 

My primary need is to make the Differential and Incremental backup on the Windows Server. When I search there is a tool Barman and PG_BackRest is available. But that will be supported only for Linux based servers only

 

Please suggest me a tool to make differential backup

 

Thanks,

Karthick Ramu

Hi Karthick

I'm a little rusty on PG (it's been about a decade since I last worked intensely with it), but I seem to remember that restoring with indexes can be very slow. The faster approach is to restore without indexes, and then create the indexes once the data restore is complete.

My knowledge may be outdated, so best to check with others that have more recent knowledge. However, it's probably worth investigating in the meantime.

Okay, I just had a quick look at the documentation, and it seems there is an option to run multiple concurrent jobs for the time-consuming parts of a restore (which includes index creation):

-j number-of-jobs

see: https://www.postgresql.org/docs/current/app-pgrestore.html (or check the docs for whatever PG version you have)

Good luck!

Hi ~~Na-iem Dollie,

 

Thanks  for your reply,

 

In SQL Server there is an option to take Full backup and Differential Backup for a particular database.

 

Like that, we need to take the differential Backup in PostgreSQL. This is my primary need.

 

Thanks,

Karthick Ramu

Hi Karthick

In that case, your are options are:

This is "like" using diff backups, but not quite the same.

OR

2. Use a 3rd party app, for example Barman or pgBackRest

Good luck!
