'''This guide provides a step-by-step method for creating regular, automated backups of your VoIPmonitor GUI's configuration. This includes users, sensors, capture rules, and all other settings configured through the web interface.'''
This guide covers backing up and restoring VoIPmonitor GUI configuration data (users, sensors, alerts, dashboards). It does '''not''' cover CDR/PCAP data backup.


== Overview ==
== Quick Reference ==
This backup procedure is designed to save '''only the GUI's configuration data''', not the call data (CDRs) or captured PCAP files. It is an essential part of a disaster recovery plan, allowing you to quickly restore a known-good GUI configuration to a new or rebuilt server without backing up terabytes of call data.


The process uses a command-line PHP script included with the GUI to export three types of data:
{| class="wikitable"
#'''Configuration Tables:''' The core database tables that store settings (e.g., `users`, `sensors`, `filter_ip`).
|-
#'''Data Tables:''' Supporting data like chart configurations and saved reports.
! Task !! Method !! Command/Path
#'''Configuration Files:''' The PHP configuration files from the GUI directory itself (e.g., `configuration.php`).
|-
| One-time backup || GUI || '''Tools → Backup & restore''' → select "configuration tables" + "configuration files"
|-
| Automated backup || CLI || <code>php run.php backupGuiTables -t config -f backup.sql</code>
|-
| Restore || GUI || '''Tools → Backup & restore''' → "restore"
|-
| Restore || CLI || <code>php run.php restoreGuiTables -t config -f backup.sql</code>
|}


== Step 1: Create the Backup Script ==
'''What Gets Backed Up:'''
First, create a shell script that will run the export commands.
* '''Configuration Tables:''' Users, sensors, capture rules, alerts, dashboards, reports
* '''Configuration Files:''' PHP config files (<code>configuration.php</code>)


;Create and edit the script file:
{{Warning|1=Restoring '''overwrites''' existing settings. Perform on fresh GUI or accept data loss.}}
<pre>
nano /usr/local/sbin/backup_voipmonitor_gui.sh
</pre>


;Copy and paste the following content into the file:

# VoIPmonitor GUI Configuration Backup Script
# VoIPmonitor GUI Configuration Backup Script

# Set the retention period in days. Backups older than this will be deleted.
RETENTION_DAYS=30
RETENTION_DAYS=30
RUN_SCRIPT="/var/www/html/php/run.php"
DAY=$(date "+%Y-%m-%d")


# --- Script Logic ---
# Create the backup directory if it doesn't exist
mkdir -p "$BACKUP_DIR"
mkdir -p "$BACKUP_DIR"


# Set the filename based on the current date
# Export configuration and data tables

# Cleanup old backups
RUN_SCRIPT="/var/www/html/php/run.php"
find "$BACKUP_DIR" -type f -mtime +"$RETENTION_DAYS" \( -name '*.sql' -o -name '*.tar.gz' \) -delete


echo "--- Starting VoIPmonitor GUI Backup for ${DAY} ---"
echo "Backup complete: $BACKUP_DIR"
</syntaxhighlight>


# Export the configuration and data tables as SQL dumps
=== Setup ===
php "$RUN_SCRIPT" backupGuiTables -t config -f "$FILE_CFG_TABLES"
php "$RUN_SCRIPT" backupGuiTables -t data -f "$FILE_DATA_TABLES"


# Backup the GUI's PHP configuration files into a compressed tarball
<syntaxhighlight lang="bash">
php "$RUN_SCRIPT" backupGuiConfigurationFiles -f "$FILE_CFG_FILES"
# Make executable and test
chmod +x /usr/local/sbin/backup_voipmonitor_gui.sh
/usr/local/sbin/backup_voipmonitor_gui.sh


echo "Backup files created:"
# Schedule daily at 3:30 AM
ls -lh "$FILE_CFG_TABLES" "$FILE_DATA_TABLES" "$FILE_CFG_FILES"
crontab -e
# Add: 30 3 * * * /usr/local/sbin/backup_voipmonitor_gui.sh > /var/log/voipmonitor_backup.log 2>&1
</syntaxhighlight>


# Clean up old backups
=== CLI Restore ===
echo "--- Cleaning up backups older than ${RETENTION_DAYS} days ---"
find "$BACKUP_DIR" -type f -mtime +"$RETENTION_DAYS" -name '*-*-*-*.sql' -print -delete
find "$BACKUP_DIR" -type f -mtime +"$RETENTION_DAYS" -name '*-*-*-*.tar.gz' -print -delete


echo "--- Backup complete ---"
<syntaxhighlight lang="bash">
</pre>
cd /var/www/html
php php/run.php restoreGuiTables -t config -f /var/backups/voipmonitor_gui/config_tables-YYYY-MM-DD.sql
php php/run.php restoreGuiTables -t data -f /var/backups/voipmonitor_gui/data_tables-YYYY-MM-DD.sql


=== Step 2: Make the Script Executable ===
# Restore config files
Set the correct permissions so the script can be run.
tar xzf /var/backups/voipmonitor_gui/config_files-YYYY-MM-DD.tar.gz -C /var/www/html/
<pre>
</syntaxhighlight>
chmod +x /usr/local/sbin/backup_voipmonitor_gui.sh
</pre>
You can test the script by running it manually: `/usr/local/sbin/backup_voipmonitor_gui.sh`. It should create three new files in `/var/backups/voipmonitor_gui`.


== Step 3: Schedule the Automated Backup with Cron ==
== What IS and IS NOT Transferred ==
The final step is to create a cron job to run the script automatically every night.


;Edit the system's crontab file:
{| class="wikitable"
<pre>
|-
crontab -e
! Transferred !! NOT Transferred
</pre>
|-
| User accounts, permissions, groups || '''Alert-to-sensor assignments''' (reconfigure manually)
|-
| Sensor definitions || '''Report-to-sensor assignments''' (reconfigure manually)
|-
| Alert/report definitions || '''Sensor user access permissions''' (reassign manually)
|-
| Dashboards, capture rules, filters || CDR data, PCAP files
|}


;Add the following line to the end of the file:
{{Note|1=Restore '''replaces''' data, it does NOT merge. Users/sensors with same ID are overwritten.}}
This example will run the backup script every day at 3:30 AM.
<pre>
30 3 * * * /usr/local/sbin/backup_voipmonitor_gui.sh > /var/log/voipmonitor_backup.log 2>&1
</pre>
* The `> /var/log/voipmonitor_backup.log 2>&1` part redirects all output (both standard and error) to a log file, which is essential for troubleshooting the cron job if it fails.


Save and close the file. The cron daemon will automatically pick up the new schedule.
== Dashboard-Only Migration ==


== Importing Only Dashboards from Another GUI Instance ==
To transfer only dashboards between GUI instances without other settings.
Use this procedure when you need to migrate dashboards from an old VoIPmonitor GUI instance to a new one without importing other configurations like sensors or capture rules.


Dashboards are stored in the `custom_config` database table, which is part of the configuration backup.
=== Simple Method (GUI) ===


=== Important Notes ===
Use standard '''Backup & restore''' - this transfers dashboards along with other config. Users are included.
* This process imports dashboards, charts, and associated reports - it is not possible to isolate only the Dashboard layouts
* Folder structures will NOT be preserved - you will need to manually recreate dashboard folders after import
* Dashboard ownership may need to be adjusted (e.g., to make dashboards public or assign to the correct user)
* Panel caching may need to be reconfigured for imported dashboards


=== Step 1: Create Backups on Both Instances ===
=== Advanced Method (SQL Extraction) ===


First, create backups on both the old and new GUI instances:
Dashboards are stored in the <code>custom_config</code> table.


'''Old GUI Server:'''
<syntaxhighlight lang="bash">
<pre>
# On source server: create backup
cd /var/www/html
cd /var/www/html
php php/run.php backupGuiTables -t config -f /tmp/old_gui_config.sql
php php/run.php backupGuiTables -t config -f /tmp/old_config.sql
</pre>


'''New GUI Server:'''
# Extract only custom_config INSERT statements
<pre>
grep "^INSERT INTO \`custom_config\`" /tmp/old_config.sql > /tmp/dashboards_only.sql
cd /var/www/html
php php/run.php backupGuiTables -t config -f /tmp/new_gui_config.sql
</pre>


The backup of the new instance is useful for rollback if the import causes issues.
# On target server: import
mysql -u voipmonitor_user -p voipmonitor < /tmp/dashboards_only.sql
</syntaxhighlight>


=== Step 2: Extract the custom_config Table from Old Instance ===
{{Note|Folder structures are NOT preserved. Recreate folders manually after import.}}


The `custom_config` table contains dashboard definitions. Extract only this table from the old instance's backup file:
== Server Migration ==


<pre>
=== Fresh Installation Method (Recommended) ===
# Extract only the custom_config table INSERT statements
grep -A 100000 "Dumping data for table \`custom_config\`" /tmp/old_gui_config.sql | \
grep -B 100000 "Table structure for table" | \
grep "^INSERT INTO" > /tmp/custom_config_only.sql
</pre>


Alternatively, you can manually extract the table by editing the SQL file and copying only the `INSERT INTO custom_config` statements.
Best for EOL systems or when historical data is not needed.


=== Step 3: Modify Dashboard Ownership (If Needed) ===
# '''Backup on old server:'''
#* GUI config: '''Tools → Backup & restore''' → "configuration tables"
#* Sniffer config: <code>cp /etc/voipmonitor.conf /tmp/</code>
#* GUI PHP config: <code>cp /var/www/html/*/configuration.php /tmp/</code>
# '''Fresh install on new server''' (see [[Sniffer_installation]], [[GUI_installation]])
# '''Restore configuration:'''
#* GUI: '''Tools → Backup & restore''' → "restore"
#* Sniffer: <code>cp voipmonitor.conf.backup /etc/voipmonitor.conf</code>
#* Update <code>interface</code>, <code>spooldir</code>, <code>server_bind</code> for new environment
# '''Update remote probes''' (if distributed): Change <code>server_destination</code> to new server IP
# '''Test with subset of traffic''' before full cutover


The `custom_config` table may contain user-specific ownership information. If you need to adjust this, edit the `/tmp/custom_config_only.sql` file:
{{Tip|1=To preserve trial license on new system, use CLI restore with <code>--exclude-table system</code>}}


<pre>
=== Data Migration Method ===
nano /tmp/custom_config_only.sql
</pre>


Common modifications:
For transferring historical CDR data with minimal downtime. See [[Redundant_database]] for:
* Change user ID values to match users on the new instance
* '''Dump/Restore:''' Simple <code>mysqldump</code> with downtime
* Set ownership to make dashboards public (if your installation supports this)
* '''Online Migration:''' Use <code>voipmonitor-migrate.conf</code> for zero-downtime sync
* Update any instance-specific paths or IDs


{{Note|
=== Cross-OS / Cloud Migration ===
The structure of the `custom_config` table includes fields that may reference user IDs and other instance-specific data. Review your SQL export carefully before importing to ensure data consistency.
}}


=== Step 4: Import the custom_config Table to New Instance ===
{{Warning|1=Do NOT clone binaries between different OS versions. Always perform fresh installation.}}


Import the extracted `custom_config` table into the new GUI instance:
* Download GUI package matching destination PHP version (see [[Re-install_the_GUI]])
* For database version mismatches, use migration instance instead of direct mysqldump


<pre>
== Cloud Token Migration ==
cd /var/www/html
mysql -u voipmonitor_user -p voipmonitor < /tmp/custom_config_only.sql
</pre>


Or use the GUI web interface if it provides a table import function.
Each cloud token has its own database. To migrate alerts/reports between tokens:


=== Step 5: Post-Import Tasks ===
# '''Contact VoIPmonitor support''' - request temporary trial cloud license
# '''Support restores''' old database to temporary license
# '''Export config''' from temporary license via '''Backup & restore'''
# '''Import config''' to new license via '''Backup & restore'''
# '''Restart sniffers:''' <code>systemctl restart voipmonitor</code>


After importing the dashboards, you will need to:
{{Note|Alert-to-sensor assignments must be reconfigured manually after migration.}}


;Recreate Dashboard Folder Structures:
== Troubleshooting ==
The import does not preserve folder hierarchies. Log in to the new GUI and manually create any dashboard folders, then move imported dashboards into the appropriate folders.


;Configure Panel Caching:
=== Backup Fails with "errno 28" (Disk Full) ===
If your dashboards use cached data for performance, you may need to reconfigure panel caching settings for the imported dashboards.


;Verify Permissions:
MySQL needs temp space for backup operations.
Check that users who should have access to the dashboards are appropriately configured in the new GUI instance.


=== Troubleshooting ===
'''Solution:''' Use smaller "configuration tables" backup instead of "data tables":
* Configuration tables: ~1-10 MB (contains all essential settings)
* Data tables: 100+ MB (supporting data, not critical)


If dashboards do not appear after import:
Check disk space: <code>df -h</code> (look at <code>/tmp</code> and <code>/var/lib/mysql</code>)
* Verify the `custom_config` table was imported correctly by checking the database
* Check for user ID mismatches between the old and new instances
* Clear browser cache and refresh the GUI
* Review any GUI error logs for related messages


== How to Restore from a Backup ==
=== Backup Breaks GTID Replication ===
There are two methods to restore your GUI configuration: the recommended CLI method or the manual method.


'''Warning:''' This process will overwrite your existing GUI settings. Perform these steps on a freshly installed GUI or be prepared to lose current configurations.
mysqldump includes GTID state by default, breaking replication on restore.


=== Method 1: Using the restoreGuiTables CLI Command (Recommended) ===
'''Solution:''' Configure mysqldump to exclude GTID:
The GUI provides a command-line tool to restore configuration tables directly without manually importing SQL files.
# '''Settings → System Configuration → Database'''
# Set '''Extra parameters for mysqldump binary:''' <code>--set-gtid-purged=OFF</code>
# Save and create new backup


;1. Navigate to your GUI directory:
Or manually:
<pre>
<syntaxhighlight lang="bash">
cd /var/www/html
mysqldump -u root -p --set-gtid-purged=OFF voipmonitor users sensors alerts custom_config > backup.sql
</pre>
</syntaxhighlight>


;2. Restore the configuration tables:
=== Alerts/Reports Missing After Upgrade ===
<pre>
php php/run.php restoreGuiTables -t config -f /var/backups/voipmonitor_gui/config_tables-YYYY-MM-DD.sql
php php/run.php restoreGuiTables -t data -f /var/backups/voipmonitor_gui/data_tables-YYYY-MM-DD.sql
</pre>


;3. Restore the Configuration Files:
Restore from backup created before upgrade:
Extract the backed-up PHP configuration files into your GUI's web root.
# '''Tools → Backup & restore''' → "restore" → upload pre-upgrade backup
<pre>
# Reconfigure alert-to-sensor assignments manually
# Extract the archive, overwriting existing files
tar xzf /var/backups/voipmonitor_gui/config_files-YYYY-MM-DD.tar.gz
</pre>


=== Method 2: Manual MySQL Import ===
== See Also ==
Alternatively, you can use the `mysql` command-line client to import the saved SQL dumps.


;1. Restore the Database Tables:
* [[Redundant_database]] - Database replication and online migration
<pre>
* [[Re-install_the_GUI]] - GUI reinstallation for PHP version changes

'''Summary:''' This guide provides a comprehensive, step-by-step method for creating automated daily backups of the VoIPmonitor GUI configuration. It clarifies that this process backs up settings, users, and rules, but not the call data (CDRs) or PCAP files. The core of the guide is a robust shell script that uses the GUI's built-in `run.php` command-line tool to export configuration tables, data tables, and PHP configuration files. The provided script also includes an automated cleanup feature to delete backups older than a configurable number of days. The tutorial details how to create this script, make it executable, and schedule it to run daily using a system cron job. The guide includes two restoration methods: the recommended CLI method using `restoreGuiTables` command and the manual method using `mysql` import. Additionally, it covers a specialized procedure for importing only dashboards from one GUI instance to another by extracting and importing the `custom_config` table, including important caveats about folder structure preservation and ownership adjustments.

This guide covers backing up and restoring VoIPmonitor GUI configuration data (users, sensors, alerts, dashboards). It does not cover CDR/PCAP data backup.

Quick Reference

Task Method Command/Path
One-time backup GUI Tools → Backup & restore → select "configuration tables" + "configuration files"
Automated backup CLI php run.php backupGuiTables -t config -f backup.sql
Restore GUI Tools → Backup & restore → "restore"
Restore CLI php run.php restoreGuiTables -t config -f backup.sql

What Gets Backed Up:

  • Configuration Tables: Users, sensors, capture rules, alerts, dashboards, reports
  • Configuration Files: PHP config files (configuration.php)

⚠️ Warning: Restoring overwrites existing settings. Perform on fresh GUI or accept data loss.

GUI Backup (Quick Method)

Ideal for one-time backups before upgrades or migrations.

  1. Navigate to GUI → Tools → Backup & restore
  2. Select "backup GUI: configuration tables"
  3. Select "backup GUI: configuration files"
  4. Click backup and download the generated file

To Restore:

  1. Navigate to GUI → Tools → Backup & restore
  2. Select "restore"
  3. Upload the backup file

Automated CLI Backup

For production environments requiring scheduled backups.

Backup Script

Create /usr/local/sbin/backup_voipmonitor_gui.sh: 

#!/bin/bash
# VoIPmonitor GUI Configuration Backup Script

BACKUP_DIR="/var/backups/voipmonitor_gui"
RETENTION_DAYS=30
RUN_SCRIPT="/var/www/html/php/run.php"
DAY=$(date "+%Y-%m-%d")

mkdir -p "$BACKUP_DIR"

# Export configuration and data tables
php "$RUN_SCRIPT" backupGuiTables -t config -f "$BACKUP_DIR/config_tables-${DAY}.sql"
php "$RUN_SCRIPT" backupGuiTables -t data -f "$BACKUP_DIR/data_tables-${DAY}.sql"
php "$RUN_SCRIPT" backupGuiConfigurationFiles -f "$BACKUP_DIR/config_files-${DAY}.tar.gz"

# Cleanup old backups
find "$BACKUP_DIR" -type f -mtime +"$RETENTION_DAYS" \( -name '*.sql' -o -name '*.tar.gz' \) -delete

echo "Backup complete: $BACKUP_DIR"

Setup

# Make executable and test
chmod +x /usr/local/sbin/backup_voipmonitor_gui.sh
/usr/local/sbin/backup_voipmonitor_gui.sh

# Schedule daily at 3:30 AM
crontab -e
# Add: 30 3 * * * /usr/local/sbin/backup_voipmonitor_gui.sh > /var/log/voipmonitor_backup.log 2>&1

CLI Restore

cd /var/www/html
php php/run.php restoreGuiTables -t config -f /var/backups/voipmonitor_gui/config_tables-YYYY-MM-DD.sql
php php/run.php restoreGuiTables -t data -f /var/backups/voipmonitor_gui/data_tables-YYYY-MM-DD.sql

# Restore config files
tar xzf /var/backups/voipmonitor_gui/config_files-YYYY-MM-DD.tar.gz -C /var/www/html/

What IS and IS NOT Transferred

Transferred NOT Transferred
User accounts, permissions, groups Alert-to-sensor assignments (reconfigure manually)
Sensor definitions Report-to-sensor assignments (reconfigure manually)
Alert/report definitions Sensor user access permissions (reassign manually)
Dashboards, capture rules, filters CDR data, PCAP files

ℹ️ Note: Restore replaces data, it does NOT merge. Users/sensors with same ID are overwritten.

Dashboard-Only Migration

To transfer only dashboards between GUI instances without other settings.

Simple Method (GUI)

Use standard Backup & restore - this transfers dashboards along with other config. Users are included.

Advanced Method (SQL Extraction)

Dashboards are stored in the custom_config table. 

# On source server: create backup
cd /var/www/html
php php/run.php backupGuiTables -t config -f /tmp/old_config.sql

# Extract only custom_config INSERT statements
grep "^INSERT INTO \`custom_config\`" /tmp/old_config.sql > /tmp/dashboards_only.sql

# On target server: import
mysql -u voipmonitor_user -p voipmonitor < /tmp/dashboards_only.sql

ℹ️ Note: Folder structures are NOT preserved. Recreate folders manually after import.

Server Migration

Fresh Installation Method (Recommended)

Best for EOL systems or when historical data is not needed.

  1. Backup on old server:
    • GUI config: Tools → Backup & restore → "configuration tables"
    • Sniffer config: cp /etc/voipmonitor.conf /tmp/
    • GUI PHP config: cp /var/www/html/*/configuration.php /tmp/
  2. Fresh install on new server (see Sniffer_installation, GUI_installation)
  3. Restore configuration:
    • GUI: Tools → Backup & restore → "restore"
    • Sniffer: cp voipmonitor.conf.backup /etc/voipmonitor.conf
    • Update interface, spooldir, server_bind for new environment
  4. Update remote probes (if distributed): Change server_destination to new server IP
  5. Test with subset of traffic before full cutover

💡 Tip: To preserve trial license on new system, use CLI restore with --exclude-table system

Data Migration Method

For transferring historical CDR data with minimal downtime. See Redundant_database for:

  • Dump/Restore: Simple mysqldump with downtime
  • Online Migration: Use voipmonitor-migrate.conf for zero-downtime sync

Cross-OS / Cloud Migration

⚠️ Warning: Do NOT clone binaries between different OS versions. Always perform fresh installation.

  • Download GUI package matching destination PHP version (see Re-install_the_GUI)
  • For database version mismatches, use migration instance instead of direct mysqldump

Cloud Token Migration

Each cloud token has its own database. To migrate alerts/reports between tokens:

  1. Contact VoIPmonitor support - request temporary trial cloud license
  2. Support restores old database to temporary license
  3. Export config from temporary license via Backup & restore
  4. Import config to new license via Backup & restore
  5. Restart sniffers: systemctl restart voipmonitor

ℹ️ Note: Alert-to-sensor assignments must be reconfigured manually after migration.

Troubleshooting

Backup Fails with "errno 28" (Disk Full)

MySQL needs temp space for backup operations.

Solution: Use smaller "configuration tables" backup instead of "data tables":

  • Configuration tables: ~1-10 MB (contains all essential settings)
  • Data tables: 100+ MB (supporting data, not critical)

Check disk space: df -h (look at /tmp and /var/lib/mysql)

Backup Breaks GTID Replication

mysqldump includes GTID state by default, breaking replication on restore.

Solution: Configure mysqldump to exclude GTID:

  1. Settings → System Configuration → Database
  2. Set Extra parameters for mysqldump binary: --set-gtid-purged=OFF
  3. Save and create new backup

Or manually: 

mysqldump -u root -p --set-gtid-purged=OFF voipmonitor users sensors alerts custom_config > backup.sql

Alerts/Reports Missing After Upgrade

Restore from backup created before upgrade:

  1. Tools → Backup & restore → "restore" → upload pre-upgrade backup
  2. Reconfigure alert-to-sensor assignments manually
