Abstract:
Method, computer program product, and system embodiments of the present disclosure may include a computing device which may set a predetermined flag on data to be copied from a primary storage tier and a secondary storage tier. The computing device may identify a first portion of the flagged data as being in a pre-migrated state stored on the primary storage tier and migrate the flagged pre-migrated data from the primary storage tier to a target medium. The computing device may identify a second portion of the flagged data as being in a migrated state stored on the secondary storage tier. The computing device may recall the flagged migrated data from the secondary storage tier to the primary storage tier and migrate the recalled migrated data from the primary storage tier to the target medium.
