Create a local repository for Backup job and then create Backup copy job in VBR console to copy backup from local repository to main repository in HQ. We use this solution for 30 branch office servers.

hmm I thought so but the incoming traffic looks more like several gigabytes. I will check again after the next weekly backup...

last night I saw the exact same behavior on another remote VEB endpoint. It looks like it first has to read/download the full backup from B&R repository and than uploads the new incremental!

Hi Patrick,

Your highest incoming traffic per second was 2040 x 0,000125 = 0.255 Megabyte. The peak was between 21 – 18 seconds, so it gives us somewhat 0.765 Megabytes of incoming traffic overall. Of course, if I am reading your network stats correctly.

the bottom scale is time. so the incoming traffic was 6pm to 9pm! 3 hours maxing the line.

Have been testing some more now and switching to "Entire Computer" from "File level backup" mode solved my issue with long backup time over my 20 Mbit/s WAN links. Time needed for backup decreased from on average 8 hours to a very nice 45 minute backup :) for my server with total data of 400 GB (very low data change rate). When i did "File Level" mode total data selected was 290 GB, VBK file has increased from 200 GB to 290 GB with Entire computer mode.

On the downside is of course more space is needed for backup files since we now backup irrelevant data but disk is cheap compared to bying more bandwidth.

So my conclusion is select Entire Computer mode (have not tested Volume level yet) on remote sites if you plan to backup over slow WAN links.

my (short) reply from support is:
CBT and checksum of transmitted blocks make a network traffic.in your infrastructure, this is behavior by design

Patrick,

Thinking of Johan post above - are using the volume level backup or file level backup (sorry if it was previously asked, cant find any info for some reason) ?

UPDATE: We checked your logs from support case - the upcoming VEB update will have the performance engine improvements and that should correct the existing behavior. Stay tuned for update.

I still see the same behavior with VEB 1.5

Job duration: 2 hours
Size: 5 GB
Read: 45 MB
Transfer: 45 MB

but outgoing traffic on the connection line from repository to endpoint is over the whole 2 hours of the job!
incoming traffic for write is only the last couple of minutes.

So I still think VEB first have to read (download) the older backups from repo on local machine and than compares and writes incremental back!?
