Trying to Understand Hyper-V Backups/Restores

i'm setting new hyper-v server , i'm trying understand how best configure backups , restores using windows server backup. have three questions:

1) partitioning ---- assume have 3 vms on server single hard drive. want able restore just one of vms.
 
what's best way partition (single) hard drive? 1 volume for host , 3 additional volumes three vm .vhds?

2) host partition? need backup/restore on host partition vms restored properly? (vm configuration files?) can done simple backup, or require full vss volume backup/restore of host partition?

3) exports/imports ---- what "export" , "import" functions in hyper-v compared to simply copying .vhd file onto empty volume , creating vm configuration it?

thanks hints. backups , restores biggest concern vms , want sure understand them best can.

have figured out, a virtual machine more vhd. configuration , files store snapshots has. people don't use snapshots , saving settings isn't important shops few virtual machines. in other words, for use cases, backing vhd sufficient. export/import preserves settings.

i use single volume on single hard drive. of clients routinely partition single drive multiple partitions. inevitably end wasting lot of time changing partition sizes when 1 fills though there ample free space on other partitions. having single partition eliminates problem.
