Ive only been using drbd about a year.
So far from pro, and probably misguided opinions :p

But I've never had any troubles with it regarding data integrity. And on my
test servers I do some pretty nasty things to it.
In fact the only troubles ive had while using drbd I only proved last night
to be the fs and not drbd's fault at all (ocfs2 is currently running dead
slow for me).

The question is what do you want it for.
I think drbd would be a good solution for a network'ed raid backup of your
disks.
If the system completely dies, or abducted by aliens, you’ve got a backup
that is less than a few seconds old (you said protocol A?).

I don’t think its suitable as an actual backup of your files.
Having reliable backups/etc are worth it even if its just that one time
"somebody" (may or may not have been me) has overwritten the wrong file on
the customers live copy.
Drbd would have gone and happily deleted the file's data like you asked.
If you were backing up with rsync its still there in the last backup you
did, and the archived backups, and the offsite copies.. etc.

So, up to you?

Andy..
