In the Skild platform, data is persisted in two key locations: 1) file system and 2) database. As is true of the entire Skild platform, the file system and database are hosted within the Amazon Web Services cloud. Skild follows best practices as advised by Amazon for maintaining secure and reliable data backup of both the file system and database.
Skild takes "snapshots" of the EBS volume utilized in production nightly, and maintains a rolling 7 day backup.
See above on how redundancy is achieved for the Skild database.
Furthermore, Skild maintains a 7 day backup of the primary database, and can revert back to a "snapshot" of the primary database anytime within the past seven days.
