We have installed Veeam on one physical server (W2K8R2, '16GB Ram Raid 5 with Veeam BackupRepository = 5 * 2 TB SATA) and have made a backup of a VM. First a full backup at 25 MB / s without any adjustments Second an incremental backup with 255 MB / s with no adjustments
now we have only 5MB / s for inkremental
the 8 Gbit Fibre Channel adapter has minimal load
I've created a backup proxy manually assign the DataStore

Sven, what transport mode is effectively being used by the proxy (and which was used previously, during the first and second job runs)? You can see it when selecting the particular VM to the left in the Realtime Statistics window (to move between job sessions, use arrows).
Do you see that behavior for all your VMs or for the specific VMs only?

In addition, to be sure SAN mode is beeing used, you can force this by editing the proxy settings, so at least transport mode can be excluded from the possible reasons of slowness (I think Alexander is suspecting an unwanted but possible failover to network mode...)
today i take a look on my VeeamServer, the SQL-Server of Veeam has 70% off CPU load from my 7 Jobs are 5 standing on detecting 2 Jobs are running very slow with 374 kbit. after i have stop the jobs the CPU load is normaly

Are you using internal SQL Express service (that installed during Veeam setup)? I've got too some performance problem with SQL slowing down backups and eventually crashing some of them, but in my scenario Veeam is in a VM with 6 Gb ram and I'm saving hundreds of VMs, so nothing comparable with you. What are the bottleneck stats now with explicit san access settings?

No, source is the source storage you are extracting vmdks from, proxy is listed apart as you can see Uhm, pure guess, are there any cuncurrent job running on the datastores that are maybe slowing down the storage? FC fabric is correctly configured?
