How to backup vembu machine

How to backup vembu machine

Hi 

I try to backup vembu machine.

My vembu machine is configured with 3 disk:
- C - system data and vembu setup
- D - Postgres db, logs and SGSTORAGE
- E - Vebu virtual disk

So If I start backup all disk on Hyper-V create a restore point but I this way my delta file for disk D, where temp file is sotored.

So Is it possibile to change the folder where temp file is stored (es. separate disk) and exclude this disk from backup or exist a better solution to backup our Vembu machine?

I evaluate the possibility to backup all file in vembu setup folder but I'm not sure this working because I need to reinsall the system and copy file, db, etc
