SQL Server 2012 Database Recovery Advisor: Simplified Point in Time Recovery

The aim of the new Database Recovery Advisor in SQL Server 2012 is to simplify the task of piecing together a recovery sequence from multiple backup files, comprising full, differential, and log backups. In this article, I'll demonstrate how the tool makes it easier to plan for, and perform, a point in time recovery from a series of backups, in order to recover data that may have been lost due to an application bug, or user error.

File Watcher Task

The task will detect changes to existing files as well as new files, both actions will cause the file to be found when available. A file is available when the task can open it exclusively. This is important for files that take a long time to be written, such as large files, or those that are just written slowly or delivered via a slow network link.

This editorial was originally published on Oct 9, 2007. It is being re-run as Steve is traveling. When I worked at JD Edwards, one of the goals of our business intelligence system was to house a single view of the truth. I recently saw a blog post by Andrew Fryer that does a good job of explaining what this actually is.
