 should be two times the total installed system size (Used). You can 
 deduct the space taken up by previous snapshots and any saved copies of
 the system from the Used amount.

 Warning: grub-efi-amd64 is not installed. The snapshot may not be compatible with UEFI. 
To disable this warning, set make_efi=no in /etc/refractasnapshot.conf or set force_efi=yes for special use.
