📦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.
