The backup concept provides for the 3-2-1 backup rule, where the numerical values stand for


  • 3 copies:
    • at least every 24 hours a snapshot of the entire storage (attachments) and the database as SSD snapshot
    • every 24 hours an incremental backup per tenant (all attachments incl. database)
    • every 24 h an offsite backup of all tenant backups from point 2
  • 2 media:
    • Snapshots/RAID on HDD/SDD
    • Tenantbackups in GCP storage buckets (cloud storage)
  • 1 external location:
    • Copy 1 + 2 are at Google and therefore in Frankfurt.
    • Copy 3 is stored encrypted at WASABI in long-term S3 storage
