Recovering Data and Servers › The Data Recovery Process

The Data Recovery Process

When an event causes loss of Master data, the data can be restored from any Replica. The recovery process is a synchronization process in the reverse direction - from a Replica to the Master.

Arcserve RHA enables you to recover data in two ways:

• Recover lost data from the Replica to the Master -- this option is a synchronization process in the reverse direction and requires you to stop the scenario. (This option is not recommended for Oracle, SQL or Exchange scenarios.)
• Recover lost data from a certain event or point in time (Data Rewind) -- This option uses a process of stamped checkpoints and user-defined bookmarks to roll corrupt data on the Master back to a time before corruption occurred.

Important! You must stop replication to initiate recovery.
