1. A computer-implemented method for backing up an in-memory database, comprising: accessing a backup server configured to perform backup operations on a database on behalf of a database server; determining whether the database is an in-memory database; utilizing database server connections to shared memory accessible to the backup server and the database server during data accesses via logical page addressing for the backup operations, when it is determined that the database is an in-memory database; and utilizing backup server connections during data accesses via physical page addressing for the backup operations, when it is determined that the database is other than an in-memory database.
