I would like to have a copy of security of the users accounts for if I have to install the server from zero.
For my this is vital for not losing the permitions of the directories and files.
I use as backup software the ArcServe that I have to copy to be able to restore the accounts without necessity of having to make a total backup of everything.
I have proven to restore alone the folder system32\config and it has not worked.
Forgive if there are errors, I am using a translator.
