KB #240099: Integrating Encryptionizer and Double-Take




Instructions on deploying Encryptionizer for SQL Server with Double-Take

Additional Information:

  • Secure SQL Server on all nodes. All nodes should share the same key(s). You should use the following options:
    • Specify “Encrypt new”, or create a Rule Mask such that the following file types are encrypted: MDF, LDF, TRN, Backup files.
  • On each node, run Regedit.exe and navigate down to one of these keys (whichever appropriate):
    • HKLM\System\CurrentControlSet\Services\NLEMSYS
    • HKLM\System\CurrentControlSet\Services\NLEMSQL
    • HKLM\System\CurrentControlSet\Services\NLEMSQL64
  • Edit the Value Group and change it from “FSFilter Encryption” to “FSFilter Anti-Virus”.
  • Exit Regedit
  • Make sure DoubleTake is disconnected. Alternatively, Stop the Double-Take Service.
  • Encrypt the database(s) on all nodes. Alternatively delete the databases on the secondary node(s) and encrypt them on the primary node.
  • Reboot the nodes.
  • Reestablish Double Take connections and allow initial syncronization to complete.
