Each of Safelink's primary databases are replicated to a second data centre to handle the possibility of network or server failure in their primary locations. Further, we take full backups of our primary databases twice daily, which enables us to roll back changes if any database were to become corrupted.
The contents of files (eg. uploaded documents) are stored separately in a highly scalable and highly available object store. A minimum of three copies of each file are retained. We retain a fourth copy in a separate secured location in order to enable recovery of items that were deleted unintentionally. The object store is geographically distributed, so the loss of nodes within the cluster or a whole data centre do not affect the availability of data.
All data that is potentially of a sensitive nature in Safelink is encrypted before it is stored to any of our databases or the object store. The backups we take are backups of the encrypted data, so the same protections apply to our backup as they do to our live system.
Users can take their own ad-hoc backups of documents in Safelink by bulk-downloading them as a zip file.
