Saving DRM keys is virtually impossible as you need a security exploit to gain root privileges BEFORE you unlock the device. The 'backup' process is essentially make a dd copy of the TZ partition.
Even if you back this up you can't do anything with it. Restoring the partition effectively takes you to the state you were in before unlocking the device. There's simply no way to keep Sony's proprietary imaging tech and also use custom software.
