Jorg,
Do you really think that ANY FS actually needs to support
more FS objects? If that would be an issue, why not create
more FSs?
A multi-TB FS SHOULD support 100MB+/GB size FS objects, which
IMO is the more common use. I have seen this alot in video
environments. The largest that I have personally seen is in
excess of 64TBs.
I would assume that just normal FSops that search or display
a extremely large number of FS objects is going to be
difficult to use. Just try placing 10k+ FS objects/files within
a directly and then list that directory.
As for backups / restore type ops, I would assume that a
smaller granularity of specified paths / directories would be
more common due to user error and not disturbing other
directories.
