Re: pg_basebackup --incremental

I created a script for incremental backup+merge on PostgreSQL 17+
It creates a full backup and later (next run) incremental backups. Incremental backups are merged to full backup with script, so you have always updated full backup.
Disclaimer: use it at your own risk.

Simple usage is:
# first backup should be full
pg_backup.sh --mode=fulll

# then inc
pg_backup.sh --mode=fincremental

Howdy,

We're running version 17.6. Would anyone be able to point me to, or provide, some sample use cases / scripts / usage to deploy a pg_basebackup full + --incremental strategy as a backup solution, please?

This will be used temporarily as we are migrating to RDS soon which is why we're not going with pgBackRest.

Thanks,

Sam
