How can I change an NTFS Volume UUID?

I just upgraded my Mac to Mac OS X El Capitan and I wanted to update my Windows 7 to Windows 10. But, before that, I need to make a backup of my Windows partition. As I've done it before, I have a Windows (NTFS) partition on a backup HDD. The thing is, I want to make a new backup with Carbon Copy Cloner, but it tell's me it can't be done because there are two volumes with same UUID. OK, then, I fight with my Windows backup partition to have it a different UUID from the one I got for my "local" Windows partition... and I'm loosing the fight ! I have this when using diskutil info /dev/disk0s2 : Device Identifier: disk0s2 Device Node: /dev/disk0s2 Whole: No Part of Whole: disk0 Device / Media Name: Windows_NTFS_Untitled_3 Volume Name: Win Mounted: Yes Mount Point: /Volumes/Win File System Personality: NTFS Type (Bundle): ntfs Name (User Visible): Windows NT File System (NTFS) Partition Type: Microsoft Basic Data OS Can Be Installed: No Media Type: Generic Protocol: SATA SMART Status: Verified Volume UUID: 24D65D1E-43E8-4FF0-BBBF-A82CC6B45D20 Disk / Partition UUID: D5C23E74-E658-45E1-B9B3-44681D0D02C2 Total Size: 85.0 GB (84999667712 Bytes) (exactly 166014976 512-Byte-Units) Volume Free Space: 34.1 GB (34093342720 Bytes) (exactly 66588560 512-Byte-Units) Device Block Size: 512 Bytes Allocation Block Size: 4096 Bytes Read-Only Media: No Read-Only Volume: No Device Location: Internal Removable Media: No Solid State: No ... and I have this using diskutil info /dev/disk1s4 : Device Identifier: disk1s4 Device Node: /dev/disk1s4 Whole: No Part of Whole: disk1 Device / Media Name: WindowsB Volume Name: Windows Mounted: Yes Mount Point: /Volumes/Windows File System Personality: NTFS Type (Bundle): ntfs Name (User Visible): Windows NT File System (NTFS) Partition Type: Microsoft Basic Data OS Can Be Installed: No Media Type: Generic Protocol: USB SMART Status: Not Supported Volume UUID: 24D65D1E-43E8-4FF0-BBBF-A82CC6B45D20 Disk / Partition UUID: C8E2A2D5-6065-4903-8BB6-AC02698323A6 Total Size: 84.7 GB (84655734784 Bytes) (exactly 165343232 512-Byte-Units) Volume Free Space: 44.0 GB (44012474368 Bytes) (exactly 85961864 512-Byte-Units) Device Block Size: 512 Bytes Allocation Block Size: 4096 Bytes Read-Only Media: No Read-Only Volume: No Device Location: External Removable Media: No As you can see, the "Disk / Partition UUID" is different, but not the "Volume UUID". Does anybody have a solution to change the "Volume UUID"?
