bdds_export.sh

Description

This script collects DNS and DHCP configuration data from a BlueCat DNS/DHCP Server (BDDS) and archives it into a compressed .tar.gz file.
It is intended for backup, migration, or troubleshooting scenarios.

Usage

Run directly on a BDDS server with sufficient permissions:

./bdds_export.sh

Requirements

  • Bash (/bin/bash)
  • Tools:
    • rndc (for journal sync)
    • named-checkconf (bind-utils)
    • tar
    • cp, mkdir, rm

Input / Output

  • Input:

    • named.conf (DNS configuration).
    • Zone files from $ZONE_DIR.
    • dhcpd.conf (DHCP configuration).

  • Output:

    • Normalized DNS config: named_<hostname>.conf
    • Copied DHCP config: dhcpd_<hostname>.conf
    • Zone files in dbs/
    • Consolidated archive: 
      /tmp/<hostname>_ddi-export_<timestamp>.tar.gz

Notes

  • Journal files are synced before copying (rndc sync -clean).
  • If named.conf, zone directory, or dhcpd.conf are missing, warnings are logged but the script continues.
  • The temporary export directory is cleaned up after archiving.
  • The archive is verified for existence after creation.
