I'm having a little trouble with my log shipping. The log backup failed with this sequence of error messages: Backup detected log corruption in database tracking. Context is FirstSector. LogFile: 2 'G:\sqllog\tracking_log.LDF' VLF SeqNo: x69d88 VLFBase: x8450000 LogBlockOffset: x8453e00 SectorStatus: 2 LogBlock.StartLsn.SeqNo: x69c72 LogBlock.StartLsn.Blk: x1f Size: x400 PrevSize: x200 Error: 3041, Severity: 16, State: 1. BACKUP failed to complete the command BACKUP LOG tracking. Check the backup application log for detailed messages. This happened about a year ago on this server and I put it down to a freak event. Now it's happened twice in a week. Different database each time. I can fix the corruption easily enough but I'm starting to worry I might be heading for a disk problem. I've checked the disk for errors in the drive properties and it says everything's fine. What do you guys recommend, please?
