1.2. Hardware requirements for installations with Backup Gateway¶
Normally, Acronis Cyber Infrastructure is installed on at least five nodes to fully utilize its built-in high availability and data redundancy capabilities. However, if you only want to use the Backup Gateway, you can deploy a very basic installation on a single virtual or physical node. Although in this case you may need to provide data redundancy by other means or risk losing user data. You can do the following:
- Use a virtual machine (VM) with at least two virtual HDDs (three disks are recommended). In this case, only one HDD will be used for data storage and you may need to make sure that the VM is made redundant by the virtualization solution it runs on.
- Use a physical server with at least two disks (three disks are recommended). Have in mind that you will need to use more disks for storage to enable data redundancy. For more details on how to plan your server configuration, refer to Planning node hardware configurations.
The following table lists the minimal hardware requirements for a node with Backup Gateway:
| Type | Management node with storage and Backup Gateway |
|---|---|
| CPU | 64-bit x86 processors with AMD-V or Intel VT hardware virtualization extensions enabled. 4 cores* |
| RAM | 8 GB |
| Storage | 1 disk: system + metadata, 120 GB SATA HDD 1 disk: storage, SATA HDD, size as required** |
| Network | 10 GbE for storage traffic 1 GbE for other traffic |
* A CPU core can be a physical core in a multicore processor if you deploy on a physical server, or a virtual core in case you deploy in a VM.
** If you plan to use Backup Gateway to store backups in the cloud, make sure the local storage cluster has plenty of logical space for staging (keeping backups locally before sending them to the cloud). For example, if you perform backups daily, provide enough space for at least 1.5 days’ worth of backups. For more details, refer to Connecting to public cloud storage via Backup Gateway.
