DBA Scripts: Backups and Recovery

Part of the DBA-Tools Project.


Backup and recovery is the one area of SQL Server administration where “probably fine” isn’t good enough, a backup you haven’t verified restores is a belief, not a backup. Nine scripts across this site cover the whole lifecycle: what recovery model each database should be in, whether backups are actually happening on schedule, whether they’re encrypted where they need to be, whether a chain is intact enough to actually restore from, and how to generate the backup and restore commands themselves.

This post is the map. It groups the nine by the question each one answers, and lays out the order they’re actually useful in, checking posture first, generating and verifying second, and recovering last.


Why Backups and Recovery Matters

  • A backup nobody has checked is a backup that might not work, the only backup you can trust is one whose restore has actually been tested or whose chain has been verified intact
  • Recovery model and backup schedule have to agree with each other, a FULL-recovery database with no log backup job is one of the most common silent failures in SQL Server, it runs fine for months until the log fills the drive
  • “We have backups” and “we could actually recover from them within our recovery point objective” are different claims, several of these scripts exist specifically to close that gap
  • Encryption, chain integrity, and restore timing all matter differently depending on the database, a one-size-fits-all backup policy misses real risk that only shows up when you actually check

The Scripts, Grouped by Question

Is the backup posture actually correct?

  • Recovery Model Audit, flags the mismatches that cause real incidents: FULL-recovery databases with no log backups, databases with no full backup at all, SIMPLE databases where someone may be expecting point-in-time recovery they don’t have
  • Backup Coverage, the baseline check, which databases have a recent full backup and which don’t

Is what’s backed up actually trustworthy?

  • Backup Chain Integrity, confirms the full-to-log backup chain is unbroken, a gap here means point-in-time restore silently doesn’t work even though backups are “running”
  • Backup Encryption Status, confirms which databases have TDE and encrypted backups, and which don’t, a compliance and security question as much as an operational one
  • Database Backup History, the full backup event history for a database, full, differential, and log, in one place

How long will a backup or restore actually take?

Doing the backup or restore itself


How They Fit Together

The order that actually makes sense in practice:

  1. Audit posture first with Recovery Model Audit and Backup Coverage, before anything else, know which databases have a real gap
  2. Verify what you already have with Backup Chain Integrity and Backup Encryption Status, “backups are running” and “the chain is intact and appropriately encrypted” are different claims
  3. Generate what’s missing with Generate Backup and Restore Scripts, once you know which databases need a full, differential, or log backup job created or corrected
  4. Plan and monitor the work itself with Backup and Restore Duration Estimate before a maintenance window, and Backup and Restore Progress while a backup or restore is actually running
  5. Review history periodically with Database Backup History, to catch a job that silently stopped running before it becomes a gap the audit scripts have to catch instead

Best Practices Across the Series

  • Run Recovery Model Audit and Backup Coverage on a schedule, not just when something already went wrong, the “accidental FULL” database is a silent failure by nature
  • Treat a chain integrity gap as urgent, a backup that’s “running” but can’t actually restore to a real point in time is worse than no backup at all, since it creates false confidence
  • Review generated backup and restore T-SQL before running it, especially restore, WITH REPLACE will overwrite an existing database
  • Re-run the audit scripts after any new database is provisioned or any recovery model is changed, new databases are exactly where backup jobs get silently missed

Summary

Nine scripts, one underlying question: if this database needed to be recovered right now, could it actually happen within the time and data-loss tolerance the business expects, and how do you know before you’re forced to find out during a real incident. Audit posture, verify the chain, generate what’s missing, and plan for the time it’ll actually take.

Start with Recovery Model Audit and Backup Coverage if you haven’t run either recently, they’re the fastest way to find out whether backup posture actually matches what everyone assumes it is.
