SUMMARY

Before you try to back up the transaction log for a database in Microsoft SQL Server 2005, you must perform a full database backup. Otherwise, you receive error messages that indicate that the BACKUP LOG statement stops abnormally. You must also perform a full database backup before you try to back up the transaction log for a database in Microsoft SQL Server 2000. However, if you do not perform a full database backup before you back up the transaction log of a database in SQL Server 2000, the BACKUP LOG statement does not stop.

In SQL Server 2005, you must perform a full database backup before you back up the transaction log for a database. Otherwise, when you try to back up the transaction log for a database, you receive the following error message:
Msg 4214, Level 16, State 1, Line 1
BACKUP LOG cannot be performed because there is no current database backup.
Msg 3013, Level 16, State 1, Line 1

In SQL Server 2000, if you try to back up a transaction log before you back up the full database, you only receive a warning message that resembles the following:
The CREATE DATABASE process is allocating 0.63 MB on disk 'SampleDatabase'.
The CREATE DATABASE process is allocating 0.49 MB on disk ' SampleDatabase_log'.
There is no current database backup. This log backup cannot be used to roll forward a preceding database backup.

Additionally, a successful backup is reported in the SQL Server Errorlog file. The text in the log file resembles the following:
2006-10-10 11:11:04.31 spid51 Starting up database ' SampleDatabase '.
2006-10-10 11:11:04.80 backup Log backed up: Database: SampleDatabase, creation date(time): 2006/10/10(11:11:04), first LSN: 8:23:1, last LSN: 8:25:1, number of dump devices: 1, device information: (FILE=1, TYPE=DISK: {'C:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\TestTlog.trn'}).
