Internet interruption causes restart instead of resume

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Begin uploading email
2. Disconnect internet connection

What is the expected output? What do you see instead?

Ideally, instead of having the transfer restart, it should resume.

Please provide any additional information below.

I have a large amount of email (~60,000) messages I was attempting to
upload. Roughly half way through, I briefly lost connectivity. The email
uploader stopped the transfer. This means that I must start from the
beginning and re-upload all mail. I may end up with a very large number of
duplicates. Instead, would it be possible to have the uploader "pause"
instead of "stop" when a connection is lost? This would save on transfer
time, time spent removing duplicates, and space used on the email account.

It's a pain to start over, but I believe duplicates will not be accepted.  I'm 
relying on this, specifically uploading 
multiple mbox's with known duplicates in order to clean them up.

Can anyone confirm that when a very large transfer gets interrupted it resumes 
where it left off and does not 
upload duplicates?

 I also had the uploader fail about 15 hours into an 18 hour upload of over 60,000 messages (an Entourage 
rge archive) and when I restarted the uploader it appeared to be re-uploading 
all the messages that were 
already transferred, giving another 18 hour estimate, so I stopped it again, 
not wanting to end up with all 
those duplicates. The reason it stopped, btw was due to a transient password 
error. There was no change to 
the password and I was still able to login to my Google apps account at that 
time with no problem, so not 
sure why it suddenly said the login failed.

I ended up restarting my transfer again after my first interruption. It made it 
a few 
hours in before it was interrupted a second time. As far as I can see, there 
were no 
additional emails uploaded (read: no duplicates).

The server will ignore duplicate message uploads. Just save time by unchecking 
the mailboxes that did 
previously upload.

Thank you for the confirmation! I'll restart it and hope for the best. As for 
unchecking the mailboxes already 
uploaded... not sure how I can be sure what was completed and what wasn't. I 
have about 30 mailboxes, many 
of them nested folders that were in Entourage and there doesn't appear to be a 
log of what's been completed 
after the Uploader is relaunched, nor a specific order in which things from the 
RGE archive would be uploaded. Is 
it alphabetical?

The uploader does not save its log automatically, so unless you kept a copy 
before restarting it, that is not 
available. You can also just search in gmail for an email from each mailbox to 
see if it was uploaded. The 
uploader does send messages to the server in the same order the folders are 
listed in the outline (tree) view, so 
start by checking for a message in the middle mailbox.

Thank you very much. I'll check the largest mailboxes in the hierarchy and 
uncheck them in the uploader if 
they've been accounted for already in my apps account.
