Agreed.
I implemented a Flashbackup policy for a server with 10M files (30 raw
disk streams, 1.4 TB) this past weekend (using the copy-on-write
method), and it saved me exactly 0 drive hours in the tape drive bank :)
Write speeds were roughly 30-50% faster, but the extra data made up for
the savings.
We run at about 60-70% usage, and were hoping to get away with not
having to divvy up the server into two categories: which filesystems to
back up with Flashbackup, and which not to. Looks like the problem is
that the file to block mapping just takes too &@*#$ long.
Cheers,
Jon

AND your filesystem is "mostly" used.
ie, you wouldn't want to use flashbackup on a 1TB filesystem that only
has 100Gig of data on it.

Flashbackups will help if you have millions of small files.
