:I don't have a 2TB file system. I have a 172GB file system that has about
:11 million files on it. They are broken down into directories to avoid
:have thousands of files in any one directory. The number of bytes isn't
:the problem in the backup it is the number of files.

:With a snapshot and dd I can avoid the issue of dump having to deal with
:all those files. I don't think there is any file system out there that
:can deal with the huge number of files efficiently. I think even NetApp
:filers have backup issues with millions of files.
This is what the journaling work is meant for... incremental realtime
backups. Snapshots are a poor hack compared to what you will be able
to do with the journaling features once they are complete.
