Restore Splunk UBA using the restore script

After you have created a backup, restore Splunk UBA using the /opt/caspida/bin/utils/uba-restore.sh script. View the command line options by using the --help option. The table lists and describes the various options that can be used in the script.

Option Description
--dateformat %FORMAT% Override the default date/time format for the backup folder name. If this option is not used, the folder name is based on ISO 8601 format YYYY-MM-DD. To specify a backup folder name in the typical format used in the United States, specify MM-DD-YYYY. Using this option also overrides the date/time format of the logging messages.
--folder %FOLDER% Override the source folder to perform the restore. By default the script looks for the restore archive in the default /var/vcap/ubabackup directory. If you used the --folder option when creating the backup to store the backup in a different directory, specify that same directory using the --folder option when restoring Splunk UBA.
--log-time Add additional logging for how long each section takes, including all function calls and tasks. Use this option to help troubleshoot issues if your restore is taking a long time.
--no-time Don't log the amount of time taken for each task.
--reset-admin-pass Reset the admin password to the system default changeme.
--skip-start-live-ds Don't start the live data sources.
--validate Validate that a restore can be successfully performed, but do not actually perform the restore.

Below is an example restore:

  1. Log in to the management node of your Splunk UBA deployment as caspida using SSH.
  2. Navigate to the /opt/caspida/bin/utils folder:
    cd /opt/caspida/bin/utils
  3. Run the restore script. In this example, we are restoring from a backup file in the /home/caspida directory from a single node system to another single node system. Below is the command and its output. Some repetitive portions of the command output are truncated for brevity:
    caspida@ip-172-31-29-247:~/bin$ ./uba-restore.sh --folder /var/vcap/ubabackup/2020-10-08_07-44-59
