Startup SAP and DB after OS backup restored

[Former Member]

Dear Friends,

As of now we are not taking os level backup for our SAP servers.

We are taking only database backup but we are planning to take the OS level backup.

Hence am expecting how to do that, I know this is not Basis activity.

So please suggest what are the options that are available to take os backup and once backup is restored how to start SAP on restored server.

Please suggest.

Thanks in advance.

Hi,

Why you are restoring one by one directories, why can't you take full OS FS level backup and restore it into new server, then start sap by changing user/sap profiles(if required)? this is the best option.

Anyways, try to start DB manually then start sap from SAPMMC....if not update this message with your status as well as the error details.

Hi Jiggi,

Trying to understond you post....

1) You want to backup the OS only.

2) You want to restore OS on a machine then restore SAP/Oracle and startup....

Is this right ?

Dear Mark,

Optino 2 is right in my case ie.

2) I want to restore OS (backup of old system to new) and then SAP and database from old system to new.

Hi,

Is this like for like OS ?

are you changing the hostname, if yes consider sapgui's external interfaces, Natted stuff through firewalls etc. ?

What is you backup solution ?

Well you will need something like :

1) a full clean backup of Oracle for starters

2) You will need to reload the oracle Software and configure the sqlnet stuff

3) Install the Central Instance

4) restore Oracle from backup.

Dear Mark,

Thanks for your reply.

We did the following things. Oracle is not having issue but SAP is not working.

1) Taken OS backup of existing server with registry and restored on new server

2) No IP and hostname change.

3) Copied usr from source to target.

4) Taken backup of existing server and restored successfully.

5) When we checked Os level services are not running and SAP is also not working.

So please suggest how resolve this issue.
