The hash comparision, as I said, is used in Venti
filesystems. That filesystem is thought for backup, and the
data storage is based on hashs. If two blocks (of arbitrary
length) have the same hash, they have the same data. The
filesystem designers made probability calculus, and
according to they words, it's much probable that the
storage media burns...

Sorry, in the last comment I was thinking of a check of the
duplicated files in a single backup, and not about the
check in differential backups.
Yes, in this last case, the hash should be stored in the
index of the archive. In fact I imagine there is a hash
stored of each file, by now.
And IMO usually there are plenty of CPU cycles to be used...

I was thinking of a hash table being build (and stored in
memory) on the fly, as files are getting into the archive.
Each new file to be added is checked against the hash
table, and if it exists, _if possible_ a byte by byte check
can be done for paranoics. _if possible_, because the full
archive may not be reachable.
I don't think storing that hash...

I've tried it, and I think it works.
It also partially solves the "comments in quotes"
problem - at least cbrowser doesn't give an error or
hang. :)
I'll have to spend more time improving juhika's patch.
Ah, the author cannot be contacted anymore through his
sf email address :(.

It still doesn't work on "\\\\".
I was writting the same patch today... It doesn't solve the
"comments in quotes" part, but at least the program never
hangs.
I'll try to attach it, but I think in the future I'll try to
improve your patch.

The patch submmited by themnemonic is not a very good
solution, because changing the linger time to 1 second
doesn't guarantee that the data will leave the TCP buffer. 1
second may not be enough for finish sending the data.
I copy another patch in order to give a new command line
option for selecting the linger time, maintaining a default
of 0 seconds...

I think this could be a good parameter. A simple hash
table, and doing comparisions between the files found
and the files already in the backup (file size,
checksum), should work. In fact this would enable even
detection of -equal- files in a backup.
There could be a parameter for telling the minimum file
size to check for a file move, as there is for
compression.
Well, some...

When I want to use this patch, I use in the directory of the scripts:
patch -p2 OverviewRowStart($line);.

Mmmmm I don't know why, but the message I did "CC:" to you
worked, and now I'm subscribed.
I promise I'd been trying to subscribe since four months
ago. Have you changed anything? I'm almost sure I haven't
touched anything in my mail system...
Anyway, it seems it works perfectly now. Thanks for the
attention!
