INTEGRATED BACKUP PERFORMANCE ENHANCEMENTS BY CREATING AFFINITY GROUPS

A method in a backup engine is described. The method includes receiving a data access request for a data element in a logical storage volume for one of a read or write operation, determining an affinity group associated with the data element based on an affinity group list indicating a physical storage volume for the data element based on the data address range for the data element, determining a first frontend adapter identifier (ID) from the first affinity group associated with the data element, the first frontend adapter ID identifying a first frontend adapter associated with a first physical storage volume, and transmitting the data access request to the first frontend adapter based on the first frontend adapter ID to execute the data access request on the first physical storage volume.
