    because proplus is very often updated, if you put back an "old station" you will lose data .
    in addition of Configuration changes, the powerup folder are especially important to allow partial download.
    if you replace Pplus with an out of date one, you will have blue triangles every where and you will have to perform total download instead of partial download. In addition if the PPLUS is AD and you have a second AD on your networks, AD wil be also corrupted.
    The best way is to have 1 P+ in spare but bakcup must be daily performed.
    The solution Emerson's Backup and Recovery allows you to perform efficient back ups

    My site is stable and running
    No changes in data base are done regularly
    Only when we have a problem
    So my vision is to have a spare pro plus on shelf to be there in case we have ours fallen or any problems with ours
    I can bear the risk of fully download the nodes
    And restart the project again

    As said
    Even on "stable" system
    Powerup folder must be daily backuped somewhere else to allow restore it in cas you have to replace your pplus
    and also take care if PPLUS is AD controller with another AD controller, AD must be always synchronised.
    And also tale car if PPLUS is also Event chronicle main server....

    pls let me introduce my system
    pro plus as PDC and chronic server
    one Historian as SDC
    second historian
    14 OWS
    1 EWS
    then as i understand and pls correct me if i am wrong
    I can make one image for p+ using acronis then restore on the new machine
    then make dialy bkp for power up folder, events file
    then in case of p+ failure i can put the other machine after copy the latest version of power up folder and the events files on it
    also please advise what should i bkp for AD and how can i sync it?

    after this only i need to download all controller and stations

    thanks for help and support

    I can make one image for p+ using acronis then restore on the new machine
    => YES

    then make dialy bkp for power up folder, events file
    => Yes

    then in case of p+ failure i can put the other machine after copy the latest version of power up folder and the events files on it
    => Yes

    also please advise what should i bkp for AD and how can i sync it?
    => if system "stable" without too much changes in users, do also acronis of your second domain controller

    after this only i need to download all controller and stations
    => No if powerup are up to date you don't need download

    If you have guardian access , please look for KBA NK-1400-0172 ProfessionalPLUS Swapout Procedure Using DeltaV Backup and Recovery Image and 

    NK-1300-0027 ProfessionalPLUS Swap-out Procedure in a Windows Server 2008, Server 2008 R2 and Server 2016 Domain Environment


    that describes an accurate procedure to restore PPLUS on a running plant and how to resynchronize AD
    If you can "stop" your plant in case of pplus failure, the procedue is much simpler.
