We are running exchange 5.5 with the lastest service pack and using Arcserve to do brick level backups. Yesterday the backup failed and the error stated that the exchange database is corrupted. I ran isinteg -pri -test alltests on it this morning and have about 200 warnings, but no errors. Does anyone know where I can find information on how to decipher these warning messages. They all seem to deal with Bad Counts and Size within reference count verification. Any help would be much appreciated.
