I have what I think is a simple question, but I haven’t been able to find a documented solution. A customer has installed DB2 v11.1 on Linux for System z. We know several ways to backup the DB2 database, logs, etc. The question I have is how best to backup the Linux server. The server itself (minus the data components) will be quite static; i.e. the DB2 software won’t change very often. The Linux sysprog is a z/VM systems programmer. His idea is to stop the database and take a Flashcopy backup of the Linux server – database and all – once a night. This will lead to all sorts of recovery problems.
What are best practices to backing up a Linux server hosting a DB2 database?
