Typically, environment size dictates your deployment model. The size of your environment takes into consideration the number of machines (physical or virtual), as well as the total size of the backed-up data. Another consideration for repository sizing is the period of retention for your backups.
Below you can find a summary of the recommended system requirements. For more detailed specs, visit the User Guide.
| CPU | RAM | GB disk | |
| Management Server (Linux-Based Backup Server) | 8 cores | 16 GB + (500 MB per concurrent job) | Disk 1: 240 GB minimum Disk 2: 240 GB minimum |
| Virtual Proxy Server | 2 cores + 1 core for each 2 additional concurrent tasks | 2 GB + 1 GB for each concurrent task | 750 MB |
| File share / NAS proxy server | 2 cores minimum 4 cores recommended + 2 cores are required for each additional concurrent task | 4 GB + 4 GB for each concurrent task | 300 MB |
| Repository Server | No more than 2 tasks per 1 CPU core | 4 GB + 1 GB for each concurrenly processed machine disk |
Get started with sizing:
- Make sure that servers that you plan to use as backup infrastructure components meet the listed system requirements.
- Veeam Sizing Estimator can provide a quick and easy method of estimating the requirements for a Veeam Backup solution.
- Veeam Backup Capacity Calculator allows to estimate capacity required to store backup data.
Pro tip: avoid the 10GB database size cap and artificial performance limitations of Microsoft SQL Server Express Edition without breaking the bank with support for free, multi-platform PostgreSQL as a configuration database engine.
