Offsite DR System Requirements

The system where you want to install the BDRSuite Offsite DR Server should meet the following requirements;

Operating System	Windows OS Windows Server 2025 Windows Server 2022(Standard, Datacenter) Windows Server 2019 (Essentials, Standard, Datacenter) Windows Server 2019 Core (Standard, Datacenter) Windows Server 2016 (Essentials, Standard, Datacenter) Windows Server 2016 Core (Standard, Datacenter) Windows Server 2012 R2 (Foundation, Essentials, Standard, Datacenter) Windows Server 2012 R2 Core (Standard, Datacenter) Windows 11 (Home, Pro)For Evaluation only Windows 10 (Home, Pro, Enterprise) For Evaluation only Linux OS Ubuntu 22.04 LTS Ubuntu 20.04 LTS Ubuntu 18.04 LTS
RAM	8 GB (Minimum) 16 GB (Recommended)
CPU	Quad-Core processor(Minimum) Octa-Core Processor(Recommended)
Network	1 Gbps & above. While replicating the on-site copy over WAN, 1 Mbps & above

Note: Only 64-bit architecture of Windows & Linux Operating Systems are supported

1. The performance of backups depends on the RAM & CPU availability of the Offsite DR Server.
   
2. Normally, 4 GB RAM will be utilized to run the Offsite DR Server and database services.
   
3. If only one backup job is active, then it will use the remaining memory (approx. 4 GB RAM).
   
4. If two concurrent backups are active, then each backup job will use approx. 2 GB RAM.
   

So, memory utilization will be divided based on active concurrent backup jobs. We recommend allocating approximately 500 MB RAM for each active, backup job. If you want to run 8 concurrent backup jobs in your Offsite DR Server, you should assign 8 GB RAM (4 GB for Offsite DR Server and 4 GB to process the backup jobs).

To avoid significant CPU usage during active, backup progress, the Offsite DR Server machine should be assigned with enough vCPUs or cores. Normally, one vCPU or core is enough to handle 8 concurrent backup jobs activity (such as read/write). However, we recommend assigning a minimum of 4 cores/vCPUs for hassle-free usage.

Note: The above-mentioned memory and CPU utilization are the same for the Offsite DR Server (Windows & Linux) deployed in physical and virtual environments.
