Use the slider to pick a point in time during any hour of the most recent day in the selected backup files. As you hover over the slider, the available time intervals display. To pick a time, click the corresponding interval.
Use the calendar interface to choose a date and time in any available month by selecting the appropriate area on the displayed day. As you hover over a day, the available hour intervals display. To pick a time, click the corresponding interval.
The calendar interface indicates whether data is available for a given date and time, based on the backup files you selected. The calendar shows when different types of backups were performed to help you choose the correct files so that you have the data you need.
Actions and tasks
Pick a date and time
You can use either the slider or the calendar to pick the exact date and time you want to recover. After you select a date and time, SQL virtual database lists which data sets will be used to create the virtual database up to the selected point in time.
Pick an LSN
SQL Server 2005 and later allows you to use a LSN (log sequence number) to identify the point at which you want to recover data. To recover up to a specific LSN range, select LSN from the drop-down menu, and then choose the appropriate backup file.
Verify data sets
Use the grid to verify which data sets will be used to create the virtual database up to the selected point in time. Depending on the point in time you selected, SQL virtual database may not need to use all the data sets available in the backup files.
