Abstract
Tracking of memory block relocation when write occur to memory blocks. After detecting a write operation to be performed on a particular target memory block, it is identified whether the write operation is due to a relocation of data from another memory block. Depending at least in part on this result, the modified data may not need to be included in a subsequent incremental backup. If appropriate, relocation data is included instead. This may potentially reduce the size of the incremental backup, especially in cases in which there were many memory block movements since the last backup, as is the case with defragmentation.
