Working with FB 2.5 on Windows 64 bit, how does Nbackup level 0 perform
compared to a high-performance copy utility like FastCopy?

I'm asking because my DB is 80+ Gbyte and both the database and the
backup are currently on the same physical disk. FastCopy works with
large chunks to minimize time wasted on disk seeks.

How does NBackup perform in this regard?

Second question: after transferring the level 0 backup file to a secure
backup volume, I want to use it to create a DB copy for test/delev/debug
purposes. I can do that using Nbackup restore, b ut does this imply
copying the entire database yet again?

With a file copy solution with Nbackup lock, I can essentially use the
copy "as is" (need to do Nbackup fixup + sweep though). I.e. a single
read+write of 80 Gbyte. Is this possible with a Nbackup level 0 backup
approach?
