HI Gray,
I'm referring to the DISK allocated to replication server during configuration.Possible on path:
\sybase\<SID>_REP\repdata_1
If you have that flexibility to re materialized the data with load dump method it is OK to go with this way,
But while you have primary and standby at two far geographical location where load dump need competitively long time, I guess this method wouldn't work.
My suggestion was if you have already configured standby server just suspend the replication connection & resume connection when you required your DR back.
Regards
Sumit
