How to get Vmprotect to create seperate Tib files?

In a previous version of acronis server i used it could be set that when you created a FUll backup it created say a 30gig file, Then each day doing an incremental it would create a 300-400mb seperate tib file then the next full it would create the 30gig file and clean up the previous files. how can i enable this behaviour in vmprotect? i have played with the retention settings however it still only creates 1 TIB file. This makes it harder to backup as i only wish to quickly backup the smaller incremental files as the FULL and any previous incremental would already have been backed up previously. This makes it much quicker transferring the data.
