Why Instant Recovery?
Traditionally, restoring a SQL database involved fully extracting the backed-up data, transferring it over the network, then rewriting it to the target SQL server. For large databases, this process could lead to significant downtime. Veeam introduced Instant Recovery about 15 years ago to solve this problem. This technology reverses the traditional process by allowing immediate database startup from the backup while performing the full restoration in the background.
Advantages of Instant Recovery for SQL Server DB
- Ultra-fast RTO (Recovery Time Objective):
- Near-immediate access to the database, typically within minutes.
- Drastic reduction in downtime, even for large databases.
- Flexibility in the restoration process:
- Three switch-over modes: automatic, manual, or scheduled.
- Ability to test restoration without impacting the production environment.
- Transparency for users:
- Restoration occurs in the background without service interruption.
- Users can access the database throughout the entire process.
- Data integrity:
- Write-cache mechanism to capture all modifications during restoration.
- Final synchronization to ensure data consistency.
- Extensive compatibility:
- Works with different versions of Microsoft SQL Server.
- Supports standalone databases and AlwaysOn availability groups.
Operation in five key steps
- Publishing the database from the backup
- Attaching to the target SQL instance
- Background file copying
- Switch-over
- Finalizing the restoration
