Tel me about Non-authoritative restore of SYSVOL or D2 restore

D2 is the default method for restoring SYSVOL and occurs automatically when you do a non-authoritative restore of the Active Directory

When you non-authoritatively restore the SYSVOL, the local copy of SYSVOL on the restored domain controller is compared with that of its replication partners. After the domain controller restarts, it replicates any necessary changes, bringing it up-to-date with the other domain controllers within the domain.
Tel me about Authoritative restore of SYSVOL or D4 restore

IN D4 restore a copy of SYSVOL that is restored from backup is authoritative for the domain. After the necessary configurations have been made, Active Directory marks the local SYSVOL as authoritative and it is replicated to the other domain controllers within the domain.

How to D2 and D4 restore?

Enable BurFlags registry to D2 or D4

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup

D2, for nonauthoritative mode, restore
D4, for an authoritative mode, restore
