I installed the same version arcserve on a 2nd server at a branch office site. I backed up data on the first server at head office to tape. Then I took the tape to the 2nd server in the branch office. However when I try to restore by session, the sessions cannot be selected, so I cannot select which files I want to restore. I can restore by backup media option successfully, but this does not let me know what files are on the backup. The restore by session option works fine if I try that on the first server. Why can't I restore by session on the second server for the same tape ?
