I was helping an old client tonight. We suddenly lost connection to the server (a Virtual Machine for a Windows Server). When we were able to connect again, we realized some differences: a folder was missing; then, we noticed a test database was missing; we also understood that the system was one week old!
How did that happen within a few minutes for no reason?!
It just shows that in the “cloud” everything is fragile. We use fragile virtualization tools. We have to make sure that we have regular backups for crucial data and files. We must upload the backups to multiple other servers in other locations.
Nothing is reliable, nothing is secure! We have to work on that basis.
