SQL Server Backup and Restore - Simple Talk

Chapter 5: Log Backups
Figure 5-6: Selecting the path and filename for your log backup file.
Note that, while a full database backup file is identified conventionally by the .BAK
extension, most DBAs identify log backup files with the .TRN extension. You can use
whatever extension you like, but this is the standard extension for native log backups
and it makes things much less confusing if everyone sticks to a familiar convention.
When you're done, click the OK buttons on both the Locate Database Files and Select
Backup Destination windows to bring you back to the main backup configuration
window. Once here, select the Options menu on the upper left-hand side of the window
to bring up the second page of backup options. We are going to focus here on just the
Transaction log section of this Options page, shown in Figure 5-7, as all the other options
on this page were covered in detail in Chapter 3.
