I am using the Document Wizard to write the Disaster Recovery Plan. Section 11 requires me to specify the archives of the person in which the records of recovery steps implementation (in paper form) are store In my company, we keep all documents and records in electronic form in Sharepoint. The IT Dept documents their technical work procedures using One Note or MS Word. DRP test reports are prepared in MS Word and filed in pdf form
If the Disaster Recovery Plan needs to be used, the assumption is that no IT system will work, therefore the only way to read through the plan and to record which steps are completed is through a paper version of the DR plan. Of course, once the systems are up and running, you can scan the paper copy and keep it in digital format.
