Glossary:Save game cloud syncing
Problem
Steam Cloud is a fantastic feature that allows configuration and save game data to synced to the cloud. However, implementation is very inconsistent among developers. Some choose to only sync config files, some force users to choose only a single slot to be synced, some have Steam Cloud listed as a feature, but do not sync any data whatsoever (check List of Steam Cloud games which do not sync save data).
However, its perfectly possibly to sync save game and config data yourself using the plethora of free cloud syncing services.
