Yep. We had a discussion with our Platinum suport TAMS and the Engineering
group recently about Backup/ignore=interlock. The DR folks where wanting to
know some specifics about file time stamps when using the backup command.
Upon recieving theanswer from engineering that you are probably talking
about. I asked specifically about using it to CLONE an OS disk. This is
not a prefered method for making a system backup, but it is fine for making
a CLONE of the OS where you are going to be changing all of the node
specific data prior to bringing up a new system pack.

I am not trying to make a backup for backup/restore purposes. I am mainly
looking for static files like installed OS patches and Licenses. Stuff that
is not changing on the system at the time that you make the CLONE image
backup. You can do a similar copy by using the HSG80 CLONE utility. But it
is not necessarily located in the HSG storage cabinet that you want to make
the new OS pack in. So, without having to move drives between HSG80 storage
cabinets, I use the above command.

When you are dealing with a 24x7 data center, this is your best option for a
no-downtime backup.
