What is Defragmentation?


Defragmentation is the process that eliminates fragmentation in file systems. It does this by reorganizing the contents of the drive in order to store the pieces of each file close together and in order (contiguously). It also attempts to create large regions of free space using free space consolidation to slow the return of fragmentation. The system performance benefits are that if the file system can find consolidated free space, new files can be created contiguously, and re-fragmentation occurs at a slower rate. Defragmentation can dramatically shorten backup times. Defragmentation could improve backup times by 30-50%.
