NoDirectSDR Registry entry for flashbackup / VCB backups

from last one year, I have seen lots of folks (with in and outside organization) asking me about NODirectSDR registry entry or I have suggested them to use it to resolve lots of problems with flashbackup for windows policy type backups. I will get some time to post an article on that and usage info. I will update the link here as well.
Thanks,
Praveen
