Synthetic Full Backup Size Greater Than the Size of Data on Disk
Synthetic full backup size may be greater than the size of the original data on disk in Windows Server 2012 and Windows Server 2016 computers.
Windows Server 2012 and Windows Server 2016 have a deduplication feature that can be enabled. When this feature is enabled, data from deduplicated volumes are backed up in their original, uncompressed state. Therefore, the size of synthetic full backups can be greater than the size of the deduplicated data.
