OK, new version is pushed. This version has a lot of changes/enhancements from the previous script, including debug/test mode, the ability to use an external configuration file (default in /etc/veeam/hana.conf) which allows you to keep different configs on each server yet use the same script on the Veeam server (also makes script upgrades easier). The script also automatically detects the HANA version and attempts to "do the right thing" for HANA 2.0 SP1 and later. It's been tested by a few customers with a number of HANA instances, but certainly interested in more feedback.
One important note, snapshot backups are still only supported in the case where there is a single tenant, even on multi-tenant databases so, while every databases is technically multi-tenant, only a single tenant is allowed if you want to backup that instance with Veeam.
