Sorry, I posted this in the wrong forum previously. Hi. I'm seeing a very interesting restore issues. I have a database in full recovery mode. I'm trying to get mirroring online on a standby server, so I'm restoring this backup to the standby server. I'm doing a full backup followed by a transaction log backup. Strangely, when I try to restore these databases on the standby server, I get a log chain error: Code: Msg 4312, Level 16, State 1, Line 2 This log cannot be restored because a gap in the log chain was created. Use more recent data backups to bridge the gap. Msg 3013, Level 16, State 1, Line 2 RESTORE LOG is terminating abnormally. This is a little strange because the transaction log back up made immediately following the full backup. Doing a little research I restored the standby database completely (with recovery), just from the full backup. I know this isn't the way to perform a restore for mirroring purposes, but I just wanted to see what was going on. Interestingly, the database come up in Simple recovery mode. Has anyone seen and issue like this? I think this is ultimately the root cause of the log chain issue. thanks!
