I have some weird performance issues in the environment of one of our customers...
The backup performance is incredibly slow at the moment and I have no clue...
Some infos about the environment:
4 ESX Hosts with local VMFS storage (RAID5 and RAID10 with BBU and Caching, no THIN-provisioning)
Veeam installed as VM on one of the hosts (18.104.22.168)
1 or 2 dedicated GBit LAN Ports for VMKernel per Host
1 up to 4 dedicated LAN Ports for normal network traffic per Host
Synology NAS connected with 1GBit
everything connected to a 48port HP GB-Switch
ESXi embedded 4.1 with installed Patch Level ESXi410-201107001
When making a backup from one machine (NBD with CTK enabled) the performance is really slow, only 2-3MB/s.
But on some machines the backup performance is fine. My first idea was a host issue, but I have made a backup for example from one machine on host 2 in 40 minutes (first backup, 100GB vmdk with 70GB used) and another one on the same host took 10 hours (first backup, 100GB vmdk with 40GB used).
Code: Select all
