Michael, Charles,
thank you for your comments. I had already seen the wikipedia entries
about ZFS, but when I have performed my tests, consisting in: generate a
program that writes a 100 MB file to disk and perform the snapshot during the
file is being written. Obviously the snapshot shows a view of the file with the
information and size it had at the time of the snapshot... so I get a portion
of it.
In order to save space I prefer no to have such half-files (mails) ,
and it is for this reason that I am asking if there is any way to prevent this.
I'm not an expert in field of file systems, so I can be asking very
naive questions... but I appreciate your comments on this topic.
Thank you
Felix
