If an error occurs on the data file disk but not on the log file disk, a transaction log backup can be made with
Microsoft SQL Server 2000. In this case, recovery up to immediately before the error is now possible by
applying the transaction log after executing snapshot restoration.
In the event that the transaction log has been backed up periodically, recovery up until the transaction log is
created is now possible if an error occurs on the log file disk.
If the transaction log backup file is lost, recovery up until the transaction log backup is created is now
impossible.
Save the transaction log backup file onto a highly reliable disk.
An example of this is that when an error occurs, disklist0.txt and snaplist0.txt are saved as valid data.
