When the backup begins all the vms on the host slows to a crawl and its pretty much unusable, slow and sluggish.
We use onhost-proxy for the two jobs (ca 55 vms pr job). The Hyper-V cluster show no sign of distress during the backup, 4-5% cpu, the vnx shows a little more disk io then usual and the Emc Datadomain with ddboost target have no issues.
Will the use of an off-host proxy do any good in this scenario?
A typical day results in this:
Job 1 (58 vms)
Job 2 (53 vms)
