configure multiple repository path in pgbackrest

Pavan Kumar-3
Hello Experts,

Is it possible to configure multiple backup repositories in pgbackrest tool in one server?
I am getting few issues with that.

https://pgbackrest.org/command.html#command-backup

3.4.9
Repository Path Option (--repo-path)
Path where backups and archive are stored.
The repository is where pgBackRest stores backups and archives WAL segments.

It may be difficult to estimate in advance how much space you'll need. The best thing to do is take some backups then record the size of different types of backups (full/incr/diff) and measure the amount of WAL generated per day. This will give you a general idea of how much space you'll need, though of course requirements will likely change over time as your database evolves.
default: /var/lib/pgbackrest
example: --repo1-path=/backup/db/backrest

Since there's a --repo1-path, then presumably there can also be a --repo2-path.

You'd presumably associate a database with repo2 by using --pg2-path

https://pgbackrest.org/command.html#command-archive-get

2.5
Stanza Options
2.5.1
PostgreSQL Path Option (--pg-path)
PostgreSQL data directory.
This should be the same as the data_directory setting in postgresql.conf. Even though this value can be read from postgresql.conf or PostgreSQL it is prudent to set it in case those resources are not available during a restore or offline backup scenario.

The pg-path option is tested against the value reported by PostgreSQL on every online backup so it should always be current.
example: --pg1-path=/data/db
Deprecated Name: db-path

Of course, this might not work, so you'll have to try it yourself.

Greetings,

While we have considered adding support for that, it's not there today.
Instead, you can pretty easily just have multiple pgbackrest.conf files
and specify which you want used on the command-line.

Documentation is here:

Thanks,

You set pg1-path and pg1-port in both v1demo and v2demo. Shouldn't v2demo use pg2-path and pg2-port?
