We are running AS2000 (fully patched) backing up the local server as well as some other servers with agents. On on the servers that are being backed up through agents, Arcserve has skipped the D:. If we do a merge of the tapes it has the C: as session 22, then it goes right to session 24 with the System State. It accounts for the session for the D: but does not have it on tape. This has happend on several backups. There is nothing in the logs to indicate any sort of problem.
