Alike A3/V7 Documentation

Prerequisites

The Alike Appliance (A3) is a purpose-built backup and DR solution which can be run as a VM or Docker image on any major hypervisor or container. Before installing your A3, have a quick look over its requirements, deployment options, and supported platforms.

After that, please proceed to Download and Install!


Minimum System Requirements (A3)
1GB RAM
16GB System disk
1GB NIC
Backup Storage for data--SMB/CIFS, NFS, cloud storage, or custom
Internet Access to quadricsoftware.com

Additional RAM can help with larger load/environments.

See Backend Tuning for more information on scaling.


Your A3 Can Be Deployed To

The A3 is most commonly deployed as a VM, but it can also be deployed as a Docker container.

Deploy your A3 as a Virtual Machine on the following platforms:
- Citrix XenServer 7.5 - 8.2 CU1
- XCP-ng
- Microsoft Hyper-V 2012R2 - 2022
The A3 has been tested as a docker container on the following platforms:
- Alpine 3.15.5 (A3 Docker reference implementation)

Other Docker platforms may work. Please see our Docker Customization section to learn more.


Your A3 Can Protect

Your A3 protects Hyper-V, Xen, and Windows Physical machines. Xen includes the two major Xen families, Citrix Hypervisor and XCP-ng. If your hypervisor is supported by your vendor, it's supported by us.

Supported Hypervisors for protection
- Citrix XenServer 7.5 - 8.2 CU1
- XCP-ng
- Microsoft Hyper-V 2012R2-2022
Supported Physical (Standalone Machine) OSs for protection
- Microsoft Windows Server 2012R2-2022
- Microsoft Windows 10 - 11

Note that A3 Physical Backups protect your physical machine at the OS level by protecting its volumes. Your A3 cannot restore a physical backup to physical hardware directly, and some restore paths may not be available, depending on disk layout, boot configuration, etc.
