Database Backup (for PMP with MySQL)

(Procedure applicable only for builds 6302 and later. For earlier versions, click here)

Data stored in Password Manager Pro database are of critical importance in any production environment, and there would be constant requirements for backing up the data for reference purposes or for disaster recovery.

To achieve this, Password Manager Pro provides two features:

    1. Live Backup of Password Manager Pro.
    2. Scheduled Backup

Live Backup

Whenever there happens an addition or modification of the entries in the Password Manager Pro database, the data immediately gets backed up. Password Manager Pro achieves this live backup by leveraging the database replication feature offered by MySQL.

A live 'slave' database could be configured in a remote location and it will get instantaneously updated whenever the 'master' database running with Password Manager Pro undergoes a change. At any point of time, the data in both the databases will be in synchronization with each other. In the unlikely event of any disaster to the primary database, you can rely on the slave database and recover the data.

To enable Live Backup,

Pre-requisite

After installation, the Password Manager Pro server should have been started and stopped at least once. If Password Manager Pro server is already running, stop it before proceeding further. Ensure that the mysqld process of Password Manager Pro is not running.

Step 1: Setup master and slave databases

  • Go to <PMP_Installation_Folder>/bin directory and run the script replicationPack.bat <FQDN of PMP Primary Server> <FQDN OF Remote Host where slave database is running > (in Windows) / replicationPack.sh <FQDN of PMP Primary Server><FQDN OF Remote Host where slave database is running>(in Linux)
  • To run this script, you need to pass the fully qualified domain names of
    (1) the host where PMP primary server is running and
    (2) the host where slave database is to be put, as commandline arguments.

    For Example: if the primary server is running at say testserver in the domain zohocorpin.com and the slave database is to be put in the host (say) testserver1 in the domain zohocorpin.com , you need to execute the above script as follows:

    In Windows

    replicationPack.bat testserver.zohocorpin.com testserver1.zohocorpin.com

    In Linux

    sh replicationPack.sh testserver.zohocorpin.com testserver1.zohocorpin.com

  • This will create the data replication package "LiveBackup.zip" under <PMP_Home>/replication folder.
  • Move this zip file from <PMP_Home>/replication folder to the remote host where you wish to keep the slave database for live backup
  • Unzip the zip file in the remote host
  • The slave database is now setup
  • The database that is bundled with PMP acts as the master database. No separate setup is required for that

Step 2: Start PMP server and slave database

  • Now, start the PMP server. This in turn starts the master database.
  • Go to the remote machine, open a command prompt with administrator privilege and navigate to the <MySQL>/bin folder and run the script startSlaveDB.bat (Windows) / startSlaveDB.sh (Linux). This will start the slave database.

Verify Live Backup Setup

After carrying out the above steps, you can verify if the Live Backup setup is working properly by looking at the message in "Admin >> General >> Database Backup" page. If the setup is proper, you will see the following:

Connection Status: Alive and Live Backup is in progress now

Slave database is running in host: <Host Name>

Recovering data from slave when master database crashes

In the rare event of master database crash, you can recover data from the slave database.

To recover the data,

  • In the remote machine where slave DB is running, navigate to <MySQL>/data folder and create a zip of the following:
    • "passtrix" directory
    • "ibdata1" file
  • Copy the zip created as above
  • Go to the machine where PMP was running
  • Get a fresh PMP installation in the machine where the master database was running
  • Navigate to <PMP_Home>/mysql/data folder and unzip the zip created from the slave database. Once you do this, the data is safely recovered in the new PMP version
  • After extracting the zip, navigate to <PMP_Installation_Folder>/conf folder, edit manage_key.conf and specify the location of pmp_key.key (encryption master key). PMP requires the pmp_key.key file accessible with its full path when it starts up every time. After a successful start-up, it does not need the key anymore and so the device with the key file can be taken offline.
  • Now, start the PMP server

Note: Once you recover the data from the slave and give life to the master database, the slave database will no longer be valid. Just delete the mysql folder in the remote machine. If you want to have the Live Backup enabled again, you need to follow the steps once again.

Scheduled Backup

You can schedule database backup to be executed at any specific point of time.

To schedule database backup,

  • Navigate to Admin >> Configuration >> Database Backup.
  • In the pop-up form that appears, select the schedule option - day, weekly or monthly.
  • Select the time at which backup has to be taken.
  • Backed up data are stored as a .zip file under <PMP_Home>/backUp directory by default. If you want, you can specify the destination directory where you wish to store the backed up contents.
  • Every time backup is executed according to schedule, one backup file will be created. You can specify the maximum number of such backup files to be kept in this directory. For example, if you choose "10" in the drop-down against the field "Maintain latest --- backups only", only the latest 10 backup files would be kept under this directory.
  • Click "Save". The required backup schedule is created.
