My company is considering contracting for traditional Disaster Recovery services. In case of a disaster, we would be provided with non-like hardware, and would have to rebuild/reload our servers from tape.
We have a few Windows servers that would be difficult to rebuild. They have modest CPU & storage requirements. I am considering moving them to VSphere Essentials or Essentials Plus with direct attached storage for DR.
I’m looking for advice on a VM backup solution. The goal is to be able to reliably schedule full backups of the VMs to an SMB share on a physical machine, so they can be backed up to tape (Backup Exec). Preferably, the VMs should be backed up while on-line, with software that is Microsoft VSS aware, and equivalent VMware technology to guarantee valid backups. If absolutely necessary, the VMs could be backed up between a scripted shutdown/startup. However, the scripted shutdown/startup would have to be extremely reliable, as the servers must be put back in production asap.
Any solution that includes a VM backup server that is difficult to rebuild, negates the “simple to restore” goal.
