• Restoring files to a remote share folder fails.
• Symptom
• When the restore destination is a remote share folder such as \\FileServer\ShareFolder\RestDes and the backup destination is a remote share folder with the same path, such as \\FileServer\ShareFolder\RestDest, the restore fails and the following error is displayed in the activity log:
• Access is denied
• Solution
• If the user account used to connect to the root share folder is not in the permission list, the restore job fails irrespective of the account used for the restore destination folder.
• Add the user account assigned for the backup destination to build the connection into the permission list of the root share folder and ensure the user account has proper permissions to restore the file.
• Add the user account into the Backup Operators group and provide the permission to override security restrictions. (85126)

• After you have upgraded the operating system, you may need to enter the encryption password again or session password when restoring a file from Arcserve UDP Agent (Windows).
• Symptom
• If encryption is enabled for the recovery point, you do not have to enter the password for recovery points backed up from the current server. However, if you upgrade the Windows OS (For example, from Windows 2008 to Windows 2008 R2), the passwords are not automatically filled in the Arcserve UDP Agent (Windows) user interface and you must enter the password again.
• Solution
• Record the recovery point encryption password or session password and keep in a safe place for retrieval.
