What is the VM backup policy at VITO?
Your user virtual machine is not backed up!
In line with other cloud environments, virtual machines should not be regarded as being persistent. This means that all data in your home directory and other system directories may be lost in case of a system failure.
To solve this, here are some suggestions:
Use version control for anything really important.
Use the 'Public' and 'Private' folder in your home directory, these are on a shared filesystem that is more persistent than regular folders, but also do not have snapshots. So if you remove or break a file, it would still be lost.
