What steps should I follow to restore a SQL backup that partially restores due to corruption?

When a SQL backup partially restores due to corruption, follow a careful step-by-step approach to recover data safely. First, avoid restoring directly to production; create a test environment to prevent further data loss. Verify the backup file’s integrity using RESTORE VERIFYONLY in SQL Server Management Studio. If corruption exists, consider restoring with the WITH CONTINUE_AFTER_ERROR option to salvage accessible data. Next, check the database consistency using DBCC CHECKDB to identify damaged objects. For severely corrupted backups, third-party Aryson SQL Backup Recovery can extract MDF and LDF files from the .bak file without losing data integrity. These tools support compressed or split backups and provide dual scanning modes for minor or major corruption. After extracting the database files, attach them to SQL Server using CREATE DATABASE … FOR ATTACH. Finally, carefully verify all tables, stored procedures, triggers, and indexes to ensure complete recovery before deploying the database to production.
