The section tells you how to back up and restore NetWitness Platform 11.x deployed on AWS virtual hosts (also referred to as VMs in this section). The two major tasks to back up and restore 11.x data in an AWS deployment are:

  • Task 1 - Backup and Export Data
  • Task 2 - Restore and Import Data

Task 1 - Backup and Export Data

  1. Export the data by running the nw-recovery-tool --export commands as described in Disaster Recovery (Backup and Restore Instructions).
  2. Record the IP addresses. You need to refer to them later in the Disaster Recovery process.

    1. Delete the all the resources of the older 11.2 VM.
    2. Deploy the fresh 11.2 VM with the same IP address, disk and resources and power it off.

    3. Follow the procedure for the NRT restoration for the respective host as described in Restore Data on a Component Host.

  3. Complete the following steps for the LogDecoder host, Decoder (Network Decoder) host, Concentrator host, and Archiver host (where host = --category.

    2. Deploy the fresh 11.2 VM with the same IP address, disk and resources listed in the 11.2 AWS Deployment Guide and power it off.

      Do not create the external disk. Only create the nwhome disks.

    3. Follow the procedure for the NRT restoration for the respective hosts as described in Restore Data on a Component Host.
    4. After you restore NRT the component host, restore the following files.
