Disaster Recovery Considerations for Copy Services
If a disaster or emergency situation at your primary production site causes you to
lose connections to the Copy Services primary server, you must manually switch

you should consider in planning for disaster recovery, and in implementing
procedures following a disaster.
Preparing for a disaster
Planning for a disaster requires some additional steps for PPRC. First, decide
where to place your primary and backup ESS Web Copy Services servers. There
