HANA recovery in DR setup

Hi Experts,

Landscape: " we have one HANA XYZ(SID) instance 00 on Host1 and same XYZ(SID) instance 00 on HOST2 for DR setup"

I have perfromed recovery on Host1. As, this is a DR landscape,

Do i need to perfrom the recovery on Host2 ? or

once after enablining the sys replication , will the systems gets sync on HOST1 & HOST2 ?

Regards,
