Abstract
A computer-implemented method, according to one embodiment, includes: selecting two previously captured snapshots and calculating a checksum for each file in each of the two snapshots. The checksums are used to determine whether the two snapshots are sufficiently similar to each other. In response to determining that the two snapshots are sufficiently similar to each other, important ones of the files in each of the two snapshots are identified. The identified important files which are located in a lower performance tier of a multi-tier data storage system are transitioned to a higher performance tier of the multi-tier data storage system. Moreover, a merged snapshot is created by merging the two snapshots, and the merged snapshot is provided for additional operations. Other systems, methods, and computer program products are described in additional embodiments.
