Windows 2012 R2, Why backup system reserved?

I have 2 options, use the automated backup or use a wbadmin script. The wbadmin command does not back up the system reserved area. Otherwise, there is a slight advantage for me to use wbadmin over the automated. My question is, what good things will come out of having the system reserved included in the backup (or what bad things will it avoid)?

Thanks

It is used for the BCD store (for booting), Windows Recovery Environment, and for Bitlocker for those editions that support it.

Just short scenario which is very possible. You backup only C: partition via wbadmin. Your drive or RAID drives. You restore from backup, and your system will not boot. These are the circumstances which couls occur if you do not backup it. As mentioned above the MSR partition is storing BootMgr file and Boot folder. These are vital for the system.
Every month I do a backup specifying the Bare Metal Recovery option. This saves my C drive, system state, and system reserve. Are you saying that if I need to do a bare metal restore and the system reserve from this monthly backup is corrupt, I can use the system reserve from the wbadmin's I'm asking about here? Or also, if something goes wrong and my system doesn't boot, the recovery function will ask for the backup containing my system reserve so it can utilize it?

You can use the system reserved partition from backup you make with wbadmin. This partition has static data and thus it is not changing. That's why you can use the volume from different backup.
