What are the recommended operating systems when creating an instance? 
We highly recommend that you consider Linux operating systems, such as Ubuntu and CentOS and refrain from using Windows, as it uses significantly more memory (due in part to the graphical interfaces, etc.).

+
How do I generate snapshot of my VM? 
You may refer to our Wiki for procedures on how to generate a snapshot of your VM.
+
Is it possible to upload images in a Science Cloud Project?

Errors Encountered
+
What will I do if I encounter an error connecting to VPN? 
This error may be caused by several factors. You may try to re-install and reconfigure the VPN by following these procedures.
+
I encountered an error that says, "Quota exceeded". What does this mean and what should I do about this? 
The error means that you have already fully-utilized the maximum allowable resources provided to you. You may check the status of your resources by accessing Compute > Overview in the Science Cloud Dashboard. To address this error, remove the unused resources in your Science Cloud Project to free up space.
+
In case we eventually encounter an error with our VMs, is there any chance that the data and instances can be recovered? 
There is no guarantee that the data and instances can be recovered in case the VM suddenly malfunctions. Hence, it is important that you personally back up your data and instances using methods like snapshots, extra volumes, external backups, etc.
