Relax-and-Recover (ReaR) disaster recovery and backup tool

Last Updated : Oct 30, 2026 |
Prolog information
Relax-and-Recover (ReaR) on Red Hat Enterprise Linux is a disaster recovery and system backup utility that creates a bootable rescue environment and captures the host operating system configuration and related system data. This allows recovery of the ASP KVM host platform in the event of issues such as data corruption.
While ReaR offers a variety of recovery configurations, Avaya does not support the use of ReaR for Virtual Machine or application-level backups on ASP 130 at this time. Following a host recovery, customers are responsible for redeploying VMs and restoring application data using independent, application-level backup procedures. Refer to individual Avaya application documentation for validated backup and restore processes.
Relax-and-Recover backup and recovery is available with ASP R7.x.
Note:
ReaR is currently supported only with standard deployments. It is not supported with encrypted deployments at this time.
For detailed guidance refer to Avaya Solutions Platform 130 R7.x Application Note: Hypervisor Backup and Recovery using Relax-and-Recover (ReaR).
