Remote storage for SQLite android

I am making an Android application and searching for service, where I can save SQlite database. The idea is that I deliver the new version of database to the server and users check and if they have old version - they update it.

The first solution I have found is standard Cloud storage like dropBox and Google Drive. But I feel that this is not quite a good soultion. Or is it?

The second solution is parse service parce. But it works only with JSON and CSV.

Are there any alternatives?

p.s. It should be free, but the database is not quite big (up to 20-30 MB maximum, including pictures).
