Common backup problems Inappropriate backup types Insufficient disk space Differential only Broken backup chain Corrupted backup file Improperly configured backups
DBCC Backups are a page level copy of the database Check structure offline Still need to check physical structure
CHECKSUM • Mathematical construct based on the page • PAGE_VERIFY • Not None • Validates page read & write • Not what is read or written • Stored with backup • Additional overhead on the system
VERIFYONLY Validates Backup set Some header fields Checksum (if used in backup) Sufficient disk space Doesn’t check entire header
RESTORE The only complete verification of a backup A backup is just a file until it gets restored Also verifies that you know how to restore
SQL Backup Pro • Full support for properly configured backup • Automated restore testing • Reporting and alerting built-in
Backup Testing • “You’re only as good as your last restore” - Kimberly Tripp • DBCC • Against Production • Against a Backup • CHECKSUM • Added overhead • VERIFYONLY • Header only without checksum • RESTORE • Like nuking from orbit, the only way to be sure
Goals • Identify common backup problems • Learn how to verify backups • Use Red Gate SQL Backup Pro to automate this process
