rsync - Jul 2004 - Growing file

Hello,
      What would be the expected behaviour of rsync, synchronizing a file
that is changing in size.
If I have a file ( say 100G ) that is being gzipped, and I start an rsync of
that file system to a remote
location, would rsync just send the data of that gzip file that exists on
disk at that point in time,
or would it keep looping seeing that the file is changing.

Thanks,
Sameer

For a growing file, it would send however much data was in the file when
rsync checked its size.  (For a shrinking file, the version of rsync in
CVS would notice that it didn't read all the data it expected and it
would skip the file.)

Of course, running rsync again would update whatever data had changed
since the last transfer.

Hi,

rsync gzip file in not so good idea!
Because of gzip algorithm, a small use change of the original file will
cause a big change of the gzip file.
That's mean rsync will copy the whole file after each change! , not what you
really want !
To over come this you can use special version on gzip, it can be fund in the
patch CSV directory or in
http://svana.org/kleptog/rgzip.html
