📦PBX Voice Recording Backup & Web Access Plan 

 ✅ Scope 

 - Automatically archive and transfer PBX call recordings from GCP-hosted Linux servers to an on-premises FTP server. - Provide web-based, password-protected access to recordings for internal staff. 

 🔁 Daily/Weekly Backup Workflow 

 Step 1: Prepare the PBX Nodes (GCP Linux Hosts) - Confirm recordings are stored under structured directories like: /var/lib/freeswitch/recordings/{hostname}/archive/{year}/{month}/ - Ensure correct file ownership (e.g. www-data) and read access. Step 2: Create a Bash Script for Scheduled Archiving - Script will: - Compress the current day/week’s recordings into a dated .tar.gz archive. - Upload the archive securely to the FTP/scp server. 

 Step 3: Automate with Cron - Schedule the script at 12:01 AM weekly or daily, depending on retention needs: 

 🌐 Web Access Setup (On-Prem FTP Server) 

 Step 4: Install IIS & Configure Web Root - Set FTP destination path as IIS web root: C:\inetpub\wwwroot\pbx-recordings - Configure basic authentication. Step 5: Implement Access Restrictions - Restrict login to local subnet IPs (e.g. 192.168.x.x) via IIS IP Restrictions. Step 6: Password-Protect Recording Directory - Use IIS features or .htaccess equivalent to secure the /pbx-recordings folder. Step 7: Simple Listing Page (Optional) - Create a minimal HTML index or use a file-listing tool for browsing recordings: 

 🔒 Security Checklist - ✅ Use strong FTP/SCP credentials. - ✅ Validate archive before upload. - ✅ Enable firewall rules to limit access. - ✅ Monitor backups and access logs.
