I'm very interested in this topic since I have been spending a lot of
time developing my "shadowmountrsync" routines which attempt to
automate the backup part of your approach outlined above. So far I
have robustly implemented startup of shadows and backup of acls (using
subinacl and/or getfacl).
Couple of questions:
1. What is 'fileacl' and how is it better/worse than subinacl?
(which seems to backup all the ACL info (vs. the limited getfacl
capabilities)
2. What does the "ntbackup of systemstate" add?
If I understand that better, I would be happy to add it as an
additional option to shadowmountrsync.
Please keep me informed on your progress on getting bare-metal
restores to work. I am very interested in getting this all working.
