Offsite DR Server
Offsite DR Server
| OS |
|
| RAM | 8 GB (Minimum) and 16 GB (Recommended) |
| Meta Data Storage | 0.1% to 0.5% of the original data size |
| CPU | 4 cores or 4 vCPUs (Minimum) and 8 cores or 8 vCPUs (Recommended) 64-bit Architecture |
| Network | 1 Gbps & above. While replicating the on-site copy over WAN, 1 Mbps & above |
| Browsers | Internet Explorer 11 & above Mozilla Firefox 53 & above Google Chrome 68 & above |
- The performance of backups depends on the RAM & CPU availability of the Offsite DR Server.
Normally, 4 GB RAM will be utilized to run the Offsite DR Server and database services.
- If only one backup job is active, then it will use the remaining memory (approx. 4 GB RAM).
- 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, 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.
The above-mentioned memory and CPU utilization are same for the Offsite DR Server (Windows & Linux) deployed in physical and virtual environments. |
