Error description

• If an unmount of a remote backup is issued without the
  /remotecomputer parameter, the unmount will fail.  However, the
  backup will be left in an inconsistent state where the backup
  server still registers the backup as mounted on the remote
  server, but the remote server will not have the backup mounted.
  For example, the following mount/unmount combination will
  produce the problem:
  tdpexcc mount backup g:=x: /remotecomputer=server1
  /remotecomputeruser=user1 /remotepassword=barney
  tdpexcc unmount backup x:

Local fix

• If the backup can be deleted, run diskshadow delete shadows on
  the remote system and run the FCM delete backup command on the
  backup system.

Problem conclusion

• The following component levels:
  - FlashCopy Manager for Microsoft Exchange 4.2 and newer
  releases
  - FlashCopy Manager for Microsoft SQL 4.2 and newer releases
   - FlashCopy Manager MMC Snapin and Base System Services 4.2
  and newer releases
  - Data Protection for Microsoft Exchange 7.1.1.1 and newer
  releases
  - Data Protection for Microsoft SQL 7.1.1.1 and newer releases
  
  have been updated so that a local unmount of a remote mounted
  backup will no longer leave the backup in a state where it
  cannot be unmounted.
