A data corruption problem may occur when you have machines with Intel 82574L or E1000E vNIC network adapters on your CA ARCserve Central Host-Based VM Backup environment. This is due to a data corruption issue of this model of network adapters when using its TCP Segmentation Offload (TSO) feature.
To avoid this problem, perform one of the following actions:
When creating a virtual machine in VMware, select different network adapters instead of E1000E.
For existing virtual machines that contain the E1000E vNIC network adapter; delete it, add a new adapter and connect it to the virtual network.
Be aware of the following conditions:
- Ensure that the environment where the CA ARCserve Central Host-Based VM Backup proxy server resides does not contain the Intel 82574L network adapter or the E1000E vNIC in its entirety.
If the backup destination is a share, then the computer hosting the share should not contain the Intel 82574L or the E1000E vNIC network adapters.
- If you must use the E1000E vNIC or if you are using a physical computer with Intel 82574L NIC installed, it is recommended that you disable the TSO feature.
