/*
sp_BlitzBackups from http://FirstResponderKit.org
This script checks your backups to see how much data you might lose when
this server fails, and how long it might take to recover.
To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.
Known limitations of this version:
- Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
Unknown limitations of this version:
- None. (If we knew them, they would be known. Duh.)
Changes - for the full list of improvements and fixes in this version, see:
https://github.com/BrentOzarULTD/SQL-Server-First-Responder-Kit/
Parameter explanations:
@HoursBack INT = 168 How many hours of history to examine, back from now.
You can check just the last 24 hours of backups, for example.
@MSDBName NVARCHAR(255) You can restore MSDB from different servers and check them
centrally. Also useful if you create a DBA utility database
and merge data from several servers in an AG into one DB.
@RestoreSpeedFullMBps INT By default, we use the backup speed from MSDB to guesstimate
how fast your restores will go. If you have done performance
tuning and testing of your backups (or if they horribly go even
slower in your DR environment, and you want to account for
that), then you can pass in different numbers here.
@RestoreSpeedDiffMBps INT See above.
@RestoreSpeedLogMBps INT See above.
