Transaction Log Guidelines
I always see many posts in the forums asking about transaction log backups and their importance. For the point in time recovery they are must in order to provide the data upto date or atleast that are committed.
Yet I have seen many articles out there explaining the importance and tasks for every DBA needs to take care:
TlogGuideline - excellent article covering all the aspects of transaction log and its features.
Backup-Recovery importance including the coverage for recovery model
KBATransLog - explanation on the transaction log
BackupRestore explanation
The above links are very useful for a newbie DBA and database support people.
