Hi Suleman,

 

is the Commserve acting as a media agent ?

 

siteA physical server Master with MA for dedu and backup destination, siteB physical server MA only for dedu and backup data destination, siteB standby commserve is VM for failover only 

 

is the DDB disk shared between the master and standby commserve ?

 

Should be no, master and standby in two site via slow wan link, I have no idea any benefit

 

Best regards,
