Backup concept of a Q.wiki Now! System

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
• RTO: 12 Std., RPO: 15 Std.
