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?
The question confuses me a bit (though maybe because weekly "full", and remainder "incremental" is pretty standard). PgBackRest really is quite simple and easy to configure if you back up to a local mount point (even when that mount point is NFS).
This is in the "postgres" crontab:
15 01 * * Sun Type=full; pgbackrest backup --stanza=nfs --type=$Type &> logs/pgbackrest_$(date +"\%F_\%T")_${Type}.log
15 01 * * 1-6 Type=incr; pgbackrest backup --stanza=nfs --type=$Type &> logs/pgbackrest_$(date +"\%F_\%T")_${Type}.log
And this is my /etc/pgbackrest.conf:
[global]
repo1-path=/Database/backups/pgbackrest
repo1-cipher-type=aes-256-cbc
repo1-cipher-pass=<redacted>
repo1-bundle=y
repo1-bundle-limit=20MiB
repo1-bundle-size=200MiB
[nfs]
pg1-path=/Database/17/data
resume=n
start-fast=y
stop-auto=y
compress-type=zst
log-level-console=detail
log-level-file=info
log-path=/var/lib/pgsql/logs/pgbackrest
retention-full=4
process-max=<nproc * 3/4>
[nfs:archive-push]
compress-type=zst
-- Death to <Redacted>, and butter sauce.
Don't boil me, I'm still alive.
