Are there any good guides or best practices for when I apply a patch, and then want to do a rollback if the patch caused a problem on a production server? In other words, is there a disaster recovery process for a production TAC and JobServer?
Unfortunately, currently there is no feature to automatically rollback an installed patch. So before installing any patch, the instructions will always tell you what you need to back up and how to recover. This is the same for Talend clients and servers.
