Async recovery - Hana DB


Dear Experts,

We recently migrated from Oracle to HANA. We have a DR site which is on prem and connectivity between DC and DR is not stable. We configured system replication using HANA studio but due to bad connectivity, the log area got full and our primary system started giving issues. we then had to stop the system replication. As a result, we are not able to use our DR site.

In oracle, what we used to do was keep the DR db in mount state and manually transfer all logs during night to DR site and apply them manually to keep the DB in sync. For this, we didnt had to perform complete recovery. just keep the logs synced and in case of switchover, manually take the DR site up. Now, this method is certainly not recommended and chances of data loss is very high but it is acceptable by us.

Is there any way by which we can do similar thing in HANA DB. like keeping the DB in mount state and keep applying logs manually without have to do restore activity afresh...??

Thanks in advance.
