The cost to SIL for an account is $24 per year. Thus far SIL has covered the cost for anyone within the organization, though this may change in the future.

This service makes archive copies of Google Drive content, Contacts, Calendar and email. Snapshots are taken 3 times a day and do not consume bandwidth on your local computer as the service accesses your Google data directly from Google.
