In a previous blog I demonstrated how to migrate an Oracle database from AWS to Oracle OCI using Data Guard. But what if you want to migrate to the Oracle Cloud, but don’t have a direct connection between the Cloud Providers, neither of the database servers are available in the public internet or you are using Oracle Standard Edition where…
Introduction RMAN backups are not a hot topic today. This is because it didn’t evolve that much in 12c/18c/19c, and most of the databases are now protected by a good backup strategy since years, and no changes are needed.

By Franck Pachot . In a previous post I started this series of “Recovery in the ☁” with the Oracle Autonomous database. My goal is to explain the recovery procedures, especially the Point-In-Time recovery procedures because there is often confusion, which I tried to clarify in What is a database backup (back to the basics).

Because I’ve seen lot of confusion about database backups (see What is a database backup (back to the basics)). On one side, in a managed database, we…
By Franck Pachot . TL;DR: do not consider a dump (like PostgreSQL pg_dump or Oracle expdp) as a database backup do not consider that your backup is successful if you didn’t test recovery databases provide physical database backups, easy and safe to restore and recover to any point-in-time between first backup and point of failure managed databases provide an easy…

The purpose of this blog is not to show how I made the setup (some dbi blogs already exists for that), but only to share a small issue I encountered during the creation of the Stanza : postgres@pgbackrest:/ [cms2] pgbackrest –stanza=cms2_primary stanza-create…
By one of our customer we use Avamar for the backup and restore solution. I was asked by this customer to find a solution to run Avamar backups for a group of databases on a specified instance. In fact, we currently try a database clone solution on some instances and clone’s databases must not be backed up, but the rest…
Introduction Sometimes you face interesting challenges with unusual environment. One of my customer needed a automated and flexible backup solution. Said like that nothing very complex you will say. But if I mention that some databases were 60TB big with more than 30 filegroups and around 600 database data files each and moreover synchronized in an AlwayOn availability group, it…
By Mouhamadou Diaw The Oracle Multitenant architecture came with Oracle 12c a few years ago. For people usually working with traditional Non-CDB database it might be confusing the first time to do Backup and Recovery with pluggable databases (PDBs) In this document we are trying to explain how to use RMAN backup and recovery in a multitenant environment for an…
