We had to call on this feature today, which was better documented on 3rd party sites to canvas' own one.
Sadly, it only put the module titles back - NOT the content within them. This is a massive gap.
Our old VLE (moodle) was (and still is - this is transition year) doing nightly backups of any changes to user activity or content in the preceding 24 hours - why does a big cloud VLE that costs money not have this capability? Even support couldn't go further than the /undelete tool, and the chap I spoke to said he was sat next to an engineer.
