Im running thru the process on how to rebuild the Web Server shown in the link below
https://documentation.commvault.com/11.42/commcell-console/web_server_hardware_refresh_setting_up_new_web_server.html

The process looks straight-forward except step 9

################################################

To restore MongoDB database on the Web Server:

a.Copy the latest MongoDB backup file. To retrive backup files, see Retrieval of Disaster Recovery (DR) Backups From Storage.
b.Run the Mongo recovery assistant tool.
############################################
Questions I have
1.  How do we get a backup of the MongoDB, it says here retrieve from DR Backup? The one in the DR backup are SQL DB files and not MongoDB?

2. Is my understanding correct that this also applies to DR backup from the Commserve for a setup where the Web Server/Command center is in a separate server from the Commserver?
3. It says run the Mongo Recovery assistant tool and then point the path to where the DR backup is? Also applies to a DR backup where the web server/Command center is in a separate server from the Commserver?


Any tips and feedback to whoever has done it already?

    Hi ​@mach123,
     

    Here are answers to your questions about rebuilding the Web Server and restoring the MongoDB database in a Commvault environment:

    1. How do we get a backup of the MongoDB? It says here retrieve from DR Backup? The one in the DR backup are SQL DB files and not MongoDB?

    - CommServe Disaster Recovery (DR) backup includes both the SQL database (CommServe DB) and the MongoDB persistent data (used by the Web Server/Command Center). While the DR backup does contain SQL DB files, MongoDB data is stored separately as MongoDB database files.

    - In the DR backup export folder (e.g., SET_XXX), you’ll find:
        - commserv_FULL.dmp (SQL DB)
        - Files like Mongo_GlobalConfigManager_xxx.7z (MongoDB dumps)

    - To restore MongoDB, you’ll need the corresponding .7z MongoDB dump file from the latest DR backup.
    - If the latest DR backup files aren’t available locally in the ER Staging Path, you can retrieve them from the Export Path.

    2. Is my understanding correct that this also applies to DR backup from the Commserve for a setup where the Web Server/Command center is in a separate server from the Commserver?

    - Yes, this applies. Even if the Web Server/Command Center is on a separate machine, the DR backup from the CommServe will include the MongoDB persistent data. You can use the DR backup from the CommServe to restore the MongoDB database on the new Web Server.

    3. It says run the Mongo Recovery Assistant tool and then point the path to where the DR backup is? Also applies to a DR backup where the Web Server/Command Center is in a separate server from the CommServe? 

    - Correct. On the new Web Server, you’ll need to run the Mongo Recovery Assistant tool following the doc on Recovering the MongoDB Database Using the Mongo Recovery Assistant Tool for Windows

    - Point the tool to the location where you’ve copied the MongoDB dump file (e.g., Mongo_GlobalConfigManager_xxx.7z) from the DR backup.
    - This process remains the same whether the Web Server is located on the same server or a separate one from the CommServe.

    Additional Info:
    **
    - Ensure you have the latest DR backup set (which should include both SQL and MongoDB dumps) before beginning the restoration.
    - Copy the DR backup files to the Web Server locally before running the recovery tool.
    - Stop all Commvault services on the Web Server before starting the restoration process.
    - After the restoration is complete, restart all Commvault services on the Web Server.
