Disaster Recovery for Transfer Workflows

"We can rebuild it from the image in an hour." True. The rebuilt server will boot, start its service, and then present a host key that forty partners have never seen. A transfer server can be rebuilt from installation media in an hour. What cannot be rebuilt from media is everything that made it yours. That includes the accounts, the host key partners have pinned, the certificates, and the folder layout. It includes the jobs and their schedules, and the partner configurations accumulated over a decade. Disaster recovery for transfer workflows means restoring all of that - and proving, before the disaster, that you can. The proving is the part most plans skip, which is why most plans work perfectly right up until they are used.

This series scopes and drills it. It covers what disaster recovery must cover beyond the server, and backing up configuration, keys, and jobs. It covers protecting key material so it is recoverable but not exposed, and the recovery runbook in restore order. It covers restore drills that prove the plan. It also covers communicating with partners while the service is down and catching up afterward. Availability during a single machine's failure is our high availability series. This one is for the day the whole thing is gone, the runbook was on the server, and the backup has never been restored.

Articles in This Series

• Disaster Recovery Scope: More Than the Server
  This article covers the full inventory to restore: configuration, accounts, keys and certificates, jobs and schedules, partner setups, in-flight data, and logs. It covers recovery time and recovery point decided per flow.
• Backing Up Transfer Configuration, Keys, and Jobs
  This article covers what to back up and in what form - exports, configuration files, job definitions. It covers how often, where, and the restorability test that separates a backup from a hope.
• Protecting Keys and Certificates for Recovery
  Secure escrow of private keys and certificates, the host key that preserves partner trust, passphrase custody, and access control on the backups themselves.
• The Transfer Disaster Recovery Runbook
  Restore order that respects dependencies, rebuilding the server, restoring configuration and keys, re-establishing jobs, verifying with partners - a copyable skeleton.
• Restore Drills: Proving the Plan Works
  Periodic restore tests in isolation, timing the recovery, the findings log, and fixing the plan while it is still a drill.
• Partner Communication During a Disaster
  Notice templates, setting expectations honestly, the catch-up after recovery, and the post-incident review that improves the plan for next time.

This series is part of the Sysax file transfer topic library. The library covers the protocols, security practices, automation techniques, and operational skills behind reliable file transfer. The library pairs well with the practical tools we build. Sysax Multi Server is a secure FTP, FTPS, SFTP, and HTTPS server for Windows. Sysax FTP Automation schedules and scripts secure transfers so the routine ones run themselves.
