## Abstract

Embodiments relate to systems and methods for service level backup using a re-cloud network. A set of operating clouds can support many users. The users can accept service based on a service level agreement (SLA), according to which the user is assured a certain level of service or support from the cloud, such as a minimum amount of uptime, a minimum amount of processor cycles or network bandwidth, or other guaranteed parameters of the usage of their virtual machine. The set of operating clouds in which the user's service is supported can be configured to communicate a service level augmentation request to a backup cloud to request additional resources to maintain the delivery of one or more SLA-specified support to users. The backup cloud network can in turn be nested with other backup clouds or resources.

## Claims

### Claim 1
