Enable delta merging
[Delta Merging (Enable delta merging)] defines whether to enable the delta merge feature for the corresponding backup set.
To enable the delta merging feature, select the [In-File Delta] tab in the [Backup Setting] menu, and select the checkbox beside [Enable delta merging].
The delta merge feature combines the full and delta files (differential or incremental) into a single full file. The advantage of using delta merge is it will speed up the restore of files. As a single 'merged' file can be restored faster than a file consisting of full plus related incremental files, which may require a lengthy merging process after restoring to a client machine. Delta merge can be applied to full and differential or incremental delta files which reside in the data area. The criteria for file merging are governed by the retention policy setting for the backup set.
