Please clarify my below 3 points:

How do we take farm backup and is there any PowerShell command for that to do in the SharePoint server,? Please clarify

once backup is done. and we are planning to perform some Maintenace activity and how do we restore the farm backup if some things wrong?

I heard our backup team will take VM snapshot backup for SharePoint servers.

is VM snapshot backup is equivalent to farm backup? and how do we restore VM snapshot backup?

FYI: It is Sharepoint 2016 with 2 wfe, 2 app and 2 DC servers in farm.

Thank you.

    1.You could backup and restore an entire farm through PowerShell or CA.


    Backup-SPFarm -Directory <BackupFolder> -BackupMethod {Full | Differential} [-Verbose]
    Restore-SPFarm -Directory <BackupFolder> -RestoreMethod Overwrite [-BackupId <GUID>]


    Go to Central Administration -> Monitoring -> Backup and Restore -> Perform a backup.

    Go to Central Administration -> Monitoring -> Backup and Restore -> Restore from a backup.

    2.Per my research, VM snapshot/backup is not equivalent to SharePoint farm backup. SharePoint farm backup only backups all data about SharePoint, VM snapshot/backup backups all data in the VM, including other software data and system settings.
