Hello Team,
Needed an expert advice.
Can you guys suggest me to a open source tool which can be used to take
incremental backup of individual Postgres databases…
We have very large databases whose sizes are again TBs when we do pg_dump
or pg_dump all its taking days to complete backups ..
Thanks in advance
Regards
Firthouse

Hi Frthouse, go look for a tool like barman using the rsync option.
Another tool might be PG backrest.
Just go to PostgreSQL.org, downloads and search the software libraries. https://www.postgresql.org/download/products/1-administrationdevelopment-tools/
Good luck,
Magnus Rolf

We use PgBackRest, and are very pleased with it.

Ditto here. It works very well and has the advantage of being able to
produce an immediately-startable copy of the master.
One caution; you have to pay attention when doing upgrades, even of
minor versions.
The other obvious option is online replication.

Replication is not a backup solution!!!!!

Thanks for your responses Ron, Karl and Magnus Rolf. I will explore on
PgBackRest….
Thanks

That's true, but once you have replication set up you have a local
staging source against which to take backups that does not require
Internet bandwidth, and thus makes solving the problem MUCH easier.
Getting the I/O from the backup process /off the production machine(s)
/is frequently a good decision. Online replication does this and moves
the locus of your backup away from the online production environment.
If that's not material simply using existing tools (e.g. pgbackrest)
does the job all by itself, but if so using replication to get the data
where its convenient to use a tool such as pgbackrest absolutely works,
separates the I/O load away from the production environment and opens up
using block-level or filesystem-level backup tools (e.g. ZFS) as well
since even if the database spans a snapshot atomic coherence boundary
(which otherwise makes doing that unsafe) you can shut the replicated
slave down, take said snapshots and restart it without implicating
accessibility to the database.
