I installed and tried to run snapshot... timeout errors... Here is what siteground support said... Is there a way to make this work on siteground.com ??
I have seen such cases before as it seems the WPMU is not compatible with our shared hosting environment. The backup tool tries to generate a complete backup of the content and database in one go.
As the process can not complete within the timeout limits the backup fails with a Gateway Timeout error. Unfortunately on our shared servers we can not increase the timeout limits to values suitable for the backup plugin.
