Question : Exchange 2007 Storage Group Logfiles and System Files

We lost the disk that holds our Storage Group Logfiles and System Files yesterday and naturally the Exchange DB dismounted. Luckily for me once I reseated the disk I was able to move the files off and onto another spare disk. We do a full backup using Backup Exec v11 and there are logs being backed up as well as the DBs. The exchange DB and logfiles/system files are on separate disks.

The question is, if this data is lost what would be the recovery process for the logfiles/system files?

Answer : Exchange 2007 Storage Group Logfiles and System Files

You would have to first determine the current state of the database by using the eseutil /mh. If the database is in a clean shutdown state, you could mount the database without the logs and it would start new log generation (it would give you an alert to this). The only data you would lose of course is anything within the log files that were not committed and lost.
if the database is in a dirty shutdown state, you would need to restore the database from backup. your data loss would be everything after the backup.
