I'm using a mixed environment consisting of 7 ESX3.5 U1 hosts and 3 ESX 4.0 hosts, backups are done via networker 7.5.1 and a VCB proxy server. Lately some of my backups have been failing, but not all. I have two groups setup to backup every weekend and they don't overlap so timing doesn't seem to be an issue. We upgraded to VCenter 4.0 a few months ago, but the problems just seem to be recent.
My questions is, should I be upgrading my VCB server to a new version, will it have an impact on my ESX 3.5 hosts ?
has anyone else been experiencing this issue lately ?
Thanks
