haven't been actively involved with cyber recovery into a vault, but the PPCR 19.12 documentation states in the NW server recovery:"The recovery sandbox is created for the NetWorker application. The latest NetWorker configuration is recovered." So I expect it to answer Y(es) to all questions that nsrdr is asking except for the recovery of the client indices, nor running a scanner -i, in case there were also backups made after the time of the NW bootstrap backup being recovered from.Hence scanner -i and nsrck -L7 are mentioned as optional.however it also states these prereqs where there is some mentioning also about obtaining credentials also for the NW application (my guess however is that one can do something with the NW server in the vault and has configured access to manage the NW server in the vault to be able to use NW NMC or NWUI, whose credentials can very likely be setup different from the original backups server, for example if the vault is to be managed by another team for clear separation of duties, as nsrdr would only restore the bootstrap of the NW server and not restore NW NMC):"PrerequisitesEnsure that the following prerequisites are met before you initiate a NetWorker recovery:● You have obtained the credentials for the Cyber Recovery vault host on which the NetWorker application is installed and for the NetWorker application.● The NetWorker server host in the Cyber Recovery vault has the same IP address and hostname as the NetWorker production host.NOTE: It is not mandatory that the IP address of the server host in the Cyber Recovery vault be the same as the NetWorker production host. However, if you use a different IP address, you might encounter issues with components and agents referring to the NetWorker server by IP address, which require manual intervention. You can avoid these issues if the IP addresses are the same.● The NetWorker application is installed in the Cyber Recovery vault and defined as an application asset in Cyber Recovery.● The DD Boost user within the vault has the same UID as the production DD Boost user.● A policy has created a point-in-time (PIT) copy to use for the recovery.● The UID associated with this copy has been created in the Cyber Recovery vault DD system.● If your deployment includes NetWorker on Windows, ensure that a Windows host and Cygwin are installed in the Cyber Recovery vault, and Cygwin OpenSSH is enabled. For more information, see the Dell PowerProtect Cyber RecoveryInstallation Guide."So in short, I don't think having different keystore passwords would matter, however after a DR it would be using the password from the original server, hence you could make life easier by keeping both in sync. But in the end it would also not matter too much, because as soon as any recoveries are performed, the NW server in the vault is very likely to be stopped or used for a next DR recovery.If in between NW in the vault would need to be updated to have it have the same version as NW prod, then not using the existing authc database, but having a new one created wouldn't matter that much either I guess, because as soon as another DR is to be performed, it will overwrite the authc DB anyways with that of the original NW server again...You would only use the NW server in the vault for recoveries, not to actually to start backups, for that you would very likely rebuild the original NW server in case it would have been affected.
I need to install Networker 19.5 version on the Networker DR environment. Is it mandatory to use the same keystore password used on the Production environment?  If I create a new keystore password, is there an option to change in the future? I am not sure if there is an impact by creating a new keystore password. Please clarify my doubt. Thanks in advance!
