Hi guys and girls, this question is one of the general sort, so forgive me if it has been answered here or in some manual I haven't red yet. Probably, I just need a simpler description. AFAIK, there are three ways to backup a database: 1. Offline filesystem backup 2. Offline backup in the databases quiesced mode via some api 3. Online backup via api
The first question I have is about the transaction log archiving. With which of the above does it make sense and why? The second one: does it make sense to run offline AND online backups in a backup cylce, or will one of them be save enough? I read through the TSM Redbook on DB2 UDB implementation. It just explains the ways RDBMS backups can be done not which combinations are useful. As far as I could extract, it is rather useless doing offline backups and log file archiving but no online backups, right?? Thanks in advance Lars
