Backup and Restore PortSIP PBX

This article provides procedures for backing up and restoring a PortSIP PBX server. The procedures are designed to ensure no data loss in upgrading and migration.

Backup files and data should be stored on a different server than the one that is used for daily running.

All procedures are performed at the command prompt and require root-level access.

Creating a Backup Using Snapshots

If your PortSIP PBX is running within a virtual environment or hosted on a cloud platform, it’s likely that these platforms offer the capability to create a snapshot of the server. This is a highly recommended method for backing up your current PortSIP PBX server.

Restoring from a Snapshot

Restoring your PBX from a snapshot is a straightforward process. Simply follow the steps provided by your virtual environment or cloud platform to restore the PBX from the snapshot you’ve created.

Remember, it’s always a good idea to test the restore process periodically to ensure your backups are working as expected. This will help you avoid any surprises in the event of a system failure.

Backing Up PBX Data

Linux

When installing PortSIP PBX for Linux, in step 3, you typically use the following command to create the PortSIP PBX Docker instance:

/bin/sh pbx_ctl.sh \
run -p /var/lib/portsip \
-a 66.175.221.120 \
-i portsip/pbx:16

In the above command used to create the PortSIP PBX Docker instance, the -p parameter is used to specify the parent folder for storing the PBX data. To back up the data, simply copy the folder /var/lib/portsip/pbx and /var/lib/portsip/postgresql to another server or an external disk.

mkdir -p /back/pbx-data
cp -p -r /var/lib/portsip/pbx /back/pbx-data
mkdir -p /back/pbx-db
cp -p -r /var/lib/portsip/postgresql /back/pbx-db

For example, if you specified the parent path as /portsip/data using the -p parameter when installing the PortSIP PBX, then you need to back up the folder /portsip/data/pbx and /portsip/data/postgresql.

mkdir -p /back/pbx-data
cp -p -r /portsip/data/pbx /back/pbx-data
mkdir -p /back/pbx-db
cp -p -r /portsip/data/postgresql /back/pbx-db

Windows

When installing PortSIP PBX for Windows, in step 1, there is an option that allows you to choose the parent folder for storing the PBX data.

To back up the data, simply copy this folder to another server or an external disk. By default, if you didn’t specify otherwise, the parent folder is C:\ProgramData\PortSIP.

The following folders need to be copied:

  • C:\ProgramData\PortSIP\pbx

  • C:\ProgramData\PortSIP\postgresql

  • C:\ProgramData\PortSIP\html

Restoring from Backup Data on Linux

Please follow the steps below to restore the PortSIP PBX from the backup data in a Linux environment.

You can't restore the backup data of a Windows PBX to a Linux PBX.

1. Stop the Currently Running PBX Instance

Execute the following commands to stop the PBX and delete the data:

cd /opt/portsip && /bin/sh pbx_ctl.sh stop
/bin/sh pbx_ctl.sh rm
rm -rf /var/lib/portsip/pbx/*
rm -rf /var/lib/portsip/postgresql/*

2. Upgrade the PortSIP PBX Docker Image (Optional)

You have the option to upgrade the PortSIP PBX Docker image before restoring the PortSIP PBX data.

First, list the PBX Docker images with the following command:

docker image list

You will get the result shown in the below screenshot.

You can then delete Docker images using the first 4 digits of the IMAGE ID for PBX and Postgresql:

docker image rm 03b8 d569

Update the PortSIP PBX Scripts

Next, delete the existing PortSIP PBX scripts:

rm install_pbx_docker.sh
rm install_docker.sh
rm pbx_ctl.sh

Download the latest installation scripts:

curl https://raw.githubusercontent.com/portsip/portsip-pbx-sh/master/v16.x/new/install_docker.sh -o install_docker.sh
curl https://raw.githubusercontent.com/portsip/portsip-pbx-sh/master/v16.x/new/pbx_ctl.sh -o pbx_ctl.sh

Install the Docker-Compose Environment

Execute the following command to install the Docker-Compose environment. If you encounter a prompt like *** cloud.cfg (Y/I/N/O/D/Z) [default=N] ?, enter Y and then press the Enter button:

/bin/sh install_docker.sh

3. Restoring a PortSIP PBX

First, copy the backup data to the PortSIP PBX server. You can use the default folder, such as /var/lib/portsip, or another folder of your choice.

For example:

mkdir -p /var/lib/portsip/pbx
cp -p -r /back/pbx-data/pbx /var/lib/portsip/
mkdir -p /var/lib/portsip/postgresql
cp -p -r /back/pbx-db/postgresql /var/lib/portsip/

The command below is used to create and run the PBX on a server with the IP 66.175.221.120. If you’re running the PBX in a LAN without a public IP, replace 66.175.221.120 with the PBX server’s private LAN IP. If you copied the backup data to a folder other than /var/lib/portsip, make sure to use the actual folder in the commands below.

/bin/sh pbx_ctl.sh \
run -p /var/lib/portsip \
-a 66.175.221.120 \
-i portsip/pbx:16

Congratulations! Your PBX has now been successfully restored.

Restoring Backup Data to a New PBX Server

The steps for restoring backup data to a new PBX server are essentially the same. The only difference is that you’ll need to use the new server’s IP address in step 5.

After signing into the PBX web portal, launch the PortSIP PBX Setup Wizard. In step 1 of the Setup Wizard, make sure to update the PBX IP address to match the new server’s IP.

Restoring from Backup Data on Windows

Please follow the steps below to restore the PortSIP PBX from the backup data in a Windows environment.

You can't restore the backup data of a Linux PBX to a Windows PBX.

1. Uninstall the Currently Running PBX Instance

  • Uninstall the PortSIP PBX from Windows

  • Delete the below PBX data folders:

    • C:\ProgramData\PortSIP\pbx

    • C:\ProgramData\PortSIP\postgresql

    • C:\ProgramData\PortSIP\html

    • C:\Program Files\PortSIP\PBX

2. Upgrading the PortSIP PBX Installer (Optional)

You have the option to upgrade the PortSIP PBX Installer before restoring the PortSIP PBX data. The latest PortSIP PBX installer for Windows can be downloaded from the PortSIP website.

3. Restoring a PortSIP PBX

First, copy the backup data to the PortSIP PBX server folders:

  • C:\ProgramData\PortSIP\pbx

  • C:\ProgramData\PortSIP\postgresql

  • C:\ProgramData\PortSIP\html

You can use the default folder as the data parent folder, such as C:\ProgramData\PortSIP, or another folder of your choice.

Next, double-click the PortSIP PBX installer to install the PortSIP PBX. In the installation UI, choose the PortSIP PBX data parent folder ( C:\ProgramData\PortSIP), then click the Next button. Wait for the installation to complete.

Congratulations! Your PBX has now been successfully restored.

Restoring Backup Data to a New PBX Server

The steps for restoring backup data to a new PBX server are essentially the same.

After signing into the PBX web portal, launch the PortSIP PBX Setup Wizard. In step 1 of the Setup Wizard, make sure to update the PBX IP address to match the new server’s IP.
