CA has set out to combine backup to disk, tape and cloud storage in a single product with the latest version of its popular software. ARCserve Backup r16 brings a sharper focus on protecting virtualised environments, includes integrated data archiving plus synthetic full backups, and can manage ARCserve D2D servers from the main Manager console.
ARCserve r16 supports host-level backup for VMware vSphere, Microsoft Hyper-V and Citrix XenServer. We tested with Hyper-V, and used a Dell R515 server running Windows Server 2008 R2 and the Hyper-V role.
The ARCserve Windows agent must be installed on the Hyper-V host, and one agent licence includes any number of guest VMs on that system. ARCserve supports snapshot-based backups using the Hyper-V VSS Writer, which allows entire VMs to be backed up and restored.
For file-level restoration, you load the ARCserve agent within each VM. After populating the ARCserve backup database using the Hyper-V host agent, any running VMs with the agent installed also appear in a separate group in the source view, where you select their virtual volumes.
We found the backup process no different to securing physical servers. For restore operations, we could select individual files and folders in the VM and return them to their original location or another destination.
as you saw it's On-Access scanning which slows the backup down. It is not the executables though but the files accessed by the backup software (thus excluding ARCserve's files and folders won't help). A noticeable to significant slowdown is expected but not a factor of more than 10.
A workaround - though I don't recommend it - is stopping and disabling the Sophos Anti-Virus service (and AutoUpdate as well as an update might restart the former) during the backup. It's an additional risk and should only be implemented of the backup duration is otherwise unacceptable. I suggest you also give Support a call.
We ahve installed Sophos v10.0 and are experiencing slowdowns, 3,800 MB/min before installation and 2,700 MB/min after installation. We are running scripts to disable the read and rename on-access scanning during the backup job, but this only covers the server that backup job runs from and does not cover the remote servers being backed up. With the scripts being used the throughput went from 2,500 MB/min to 2,700 MB/min, which is not an improvement in our opinion. 2b1af7f3a8
