I have a problem with syncronizing mail via portable home directory
to the server. If i include ~/Library/mail in the login/logout-
sync, the login/logout process takes far above 5 minutes for my
1,31 GB. Is this a normal behavior? In my understanding, it is a
simple differential comparsion and should only take a few seconds,
depending on the amount of mails.
For sure, the first login takes longer, because all necessary files
are going to be transferred. But if the mirror on the home server
already exist, the comparsion and transfer of the files should be
real fast.
I'm not totally intimate with the file sync engine, but I suspect the
problem here is a very large number of round-trips across the network
connection. Even if the files are tiny and the operation is basic,
the network latency adds up. If the sync time is proportional to the
number of emails in ~/Library/Mail, that would be a good indication
that this is the case. Afaik, the comparison is done on a file by
file basis, and all the processing happens locally.
Maybe you already know about IMAP, but it might save you some time /
resources to not have to back up every client's mail from their
workstation, when that mail is already stored on the mail server
(which would be backed up).

The main goal is to have a backup of all necessary files from all
users on our Backup Server without influencing the work process of
a user.
Thanks for your answers :)
