Data security

Backup strategy

All our data backups are designed for a data retention rate of 99.999999999% over one year.

  • Redundant database cluster on two availability zones<
  • Incremental backups every second for 3 days
  • Daily full backups on S3 for 7 days
  • Weekly backups to S3 for unlimited runtime
  • Backups at AWS independent backup system in the Netherlands with object locking compliance mode for 90 days
  • Optional: automated daily backup on site at the customer's premises

Encryption

All backups are stored in encrypted form, with each backup being encrypted with its own key (all keys are encrypted with their own master key, which is changed on an ongoing basis). The 256-bit Advanced Encryption Standard(AES-256) is also used to encrypt the backups. No practically feasible attack is known for this procedure.
