- They will retain 14 copies of the database backup and two copies of the content backup.
- They can restore a site from any of those snapshots.
- It will all be documented in the SLA.
It is also possible for a site administrator to back up their WordPress site, or selected pages, posts, via tools->Export.
For individual pages, it is possible to go back to a previous version, by browsing the Revisions on the Edit Page. (Check Screen Options near the top to ensure you can see Revisions.)
