    From the screen shots that you have sent it seems that upload for DailyData is done in 3 secs and upload for Backupset1 is in progress.

    Can you pl. send us the logs so that we can debug if the upload actully happened or not.

    Parallel backups of different backup sets are possible but for same backupset multiple uploads/backups are not supported.

    I looked at the image again and realize that the backup was failed for that particular backuprun. So I guess the files uploaded were very small in size and thats why took just few seconds to upload.

    Actually the upload should not start if the backuprun fails. Will fix that bug.

    When you compare ZIB performance to ISP bandwidth meter test results, please remember:

    1. ZIB communication to Amazon data center is using SSL. SSL will take additional
    time.
    2. In case of ZIB, you are measuring transfer from your data center to Amazon data centers via your ISP. We do not know how far the ISP is from Amazon data centers.
    3. ZIB performance includes the time to get packet ack from Amazon.

    We measure ZIB performance and compare it to performance seen by other tools (We use jets3t tool for comparison). ZIB performs better than other tools.

    The performance reported by you appears reasonable.

    We are also working on performance improvements that you can take advantage in next couple of releases.

    Noted, but not this dramatic!

    Our ISP at the furthest is Portland, OR (most likely here in Vancouver, WA) the nearest data center is less than 200 miles in Seattle, WA. There are also others in LA and Palo Alto which are like 700-800 miles. Even if i run the speed test to NY it really only ups latency not much lower in speed.

    ACK's are required for all transmissions, and generally included in transfer rates. I fail to see how that statement makes any difference.

    I know! We have nearly 2 MBps effective upload rate even during peak use hours. ZIB won't upload any faster than 65 KBps. There has to be something else going on here!!

    Well, your product is doing us no good at all unless we can upload before the next day's backup starts. Effectively I have the same result as before applying the patch you posted: a bunch of backups taking up space not being uploaded.

    Should we just give up and get a refund? I know there are lots of alternatives. Heck, I could backup our files myself and upload them with the S3 web interface.

    I would like to use this tool, and service if it can work for us in practice not just theory. Right now though, it's just wasting our IT resources and costing us money. I will post a new thread about the upload issue, but I think that maybe this issue is similar to the one I had before the patch, coding errors.
