I'm wondering if someone can help me. I have recently taken over looking after another server and when I took it on one of the databases had failing transaction log backups due to corruption in the T-Log backup. I researched how to fix this and found Paul Randall's advice
http://www.sqlskills.com/blogs/paul/how-can-a-log-backup-fail-but-a-full-backup-succeed/ which I followed and all worked and the T-log backups worked. Now every few days it happens again and although I can fix it I need to get to the root cause and I'm struggling to figure it out. Has anyone got any ideas on why this happens so I can fix it at source. Many thanks
Do you have any other database's transaction logs on that same disk volume? Are they also suffering the same problem? If this is the only file on that volume then maybe it's something wrong with the underlying disk?
