/*
sp_AllNightLog from http://FirstResponderKit.org
* @PollForNewDatabases = 1 polls sys.databases for new entries
* Unfortunately no other way currently to automate new database additions when restored from backups
* No triggers or extended events that easily do this
* @Backup = 1 polls msdbCentral.dbo.backup_worker for databases not backed up in [RPO], takes LOG backups
* Will switch to a full backup if none exists
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! And really, maybe not even anything less than 2016. Heh.
- When restoring encrypted backups, the encryption certificate must already be installed.
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:
@PollForNewDatabases BIT, defaults to 0. When this is set to 1, runs in a perma-loop to find new entries in sys.databases
@Backup BIT, defaults to 0. When this is set to 1, runs in a perma-loop checking the backup_worker table for databases that need to be backed up
@Debug BIT, defaults to 0. Whent this is set to 1, it prints out dynamic SQL commands
@RPOSeconds BIGINT, defaults to 30. Value in seconds you want to use to determine if a new log backup needs to be taken.
@BackupPath NVARCHAR(MAX), defaults to = ''D:\Backup''. You 99.99999% will need to change this path to something else. This tells Ola''s job where to put backups.
