Abstract
Improving the performance of read operations in a restore path of a backup system by adaptively applying compression. The method defines an extent covering data segments for which compression ratio statistics are calculated, and calculates a respective compression ratio for each data segment in the defined extent. It then associates each unique compression ratio with a corresponding index value and stores each compression ratio and associated corresponding index value in an array. The array is appended as extended file attribute to the data segments, the indexed compression ratio is used by a backup server to determine whether or not to apply compression to the data segments in a restore path sending the data segments from the backup server.
