With the Intel® Client Backup and Recovery software provided with the SS4000, you're able to do a bare metal system recovery. However, this is performed by booting to the SS4000 Recovery CD from the client system. The bootable CD utility provides network drivers and SS4000 access credentials.
I don't know if Shadow Protect from StorageCraft will provide that capability. You're correct, you'll have no AD. Unfortunately Intel hasn't tested other backup and recovery utilities with the SS4000.
My suggestion would be to test the backup and recovery plan you have to see if it works before disaster strikes.
