Ordering of switches is important, but only for the --include* --exclude*
switches. For your sample command there should be no difference.
We also use NetApp filers and exclude .snapshot, the same way you have. It
works fine... The
--delete command won't help here as it will delete everything on the
destination that is not on the source but will not delete .snapshot. To do
that you need --delete-excluded. However I don't think that is your
solution. Using --exclude is what you want, hopefully you can find a typo
somewhere that is causing you grief.
With compression you will end up doing the compression and decompression on
the same box -it slows things down big time. Effectively, as far as your
machine is concerned, both directories are on the same box. Even if you were
using two different hosts on a gb lan, we have found that compression slows
things down by about 60%. The CPU's simply cannot keep up with the LAN. The
other switch you should use is -W. It deals with whole files and is
significantly quicker.

Subject: question on switches and their order
Does it matter what order the options/switches are placed? I ask
because I did an initial rsync of data from a NetApp to a SAN box using
the following:
rsync -avz --exclude=.snapshot /mail-data/ /mnt
The .snapshot directory is only useful to Ontap in this instance so I
did not want it transfered. It seemd to work correctly and all was
fine. Until I tried to run an update using the following:
rsync -avz --exclude=.snapshot --delete /mail-data/ /mnt
This transfered the .snapshot directory and filled the partition. Is
the above incorrect? Should it be like this:
rsync --exclude=.snapshot --delete -avz /mail-data/ /mnt
Also, do I need the 'z' if I have a gigabit network? I think it would
put more strain on the filer than necessary and actually slow transfer
time.
Thanks.
