We are hosting TeamCity (Continunos Integration) and Atlassian Jira and Confluence tools in the same Azure VM with Linux Ubuntu (LTS 14.04) as OS.
As all the tools reside on the same VM, would a periodic VM backup be the best approach to backup them? Or rather implement a tool specific approach would be better?
As example, considering Team City, it is suggested to call its REST API to run the backup.But this requires to write little apps for each tools, while the VM backup would take them all in my opinion.
VM snapshot is easy to manage and easy to restore, but you have the risk of losing whole data in case of corruption. Take a periodic backup of all your applications from Azure to local infrastructure but keep a snapshot for quick recovery.
