Endpoint Encryption

Issue/Introduction

The technology behind commercial backup-and-restore solutions—including Microsoft Backup and Restore—varies greatly; therefore, restoring volume(s) directly on a disk encrypted by Symantec Endpoint Encryption Drive Encryption is not guaranteed.

Resolution

A best practice for successful restoration is to always decrypt the disk first.

If you cannot decrypt the disk before you try to restore it, use the following workaround at your own risk:

  1. 1. Restore your backup by following the instructions that your third-party software vendor provided.

    Warning: Do not proceed to the next step unless the third-party software reports that you have successfully restored your backup. If the third-party software cannot restore your backup while the disk is encrypted, you must decrypt the disk before trying to restore it again.
    If you cannot boot into Microsoft Windows to decrypt the disk, decrypt the disk using the recovery disc that you prepared after installing Drive Encryption.
     
  2. Follow the third-party software instructions to restart the computer.

    Note: You might have to reset the master boot record (MBR) if the system does not boot and you receive a BIOS-level error message similar to one of the following messages:
     
    • Operating System Not Found
    • Missing Operating System
    • Non-system Disk or Disk Error
    • BOOTMGR is missing
    • Automatic Repair

An overall best practice for creating useful backups is to choose volume-based backups instead of file-based backups.
