Minimum System Specification requirement for our Unison App to install in the machine.
The Unison App is designed to run continuous backup operations while systems remain in active use.
Meeting the minimum system requirements ensures installation stability, consistent backup execution, and reliable recovery when needed.
This page is intended for IT administrators and system owners preparing a machine for Unison installation.
For recovery reliability context, see Backup Verification & Recovery.
Minimum System Requirements
The Unison App requires the following minimum system specifications to install and operate reliably.
| Component | Requirement |
| Operating System |
Windows 10 (64-bit) or later Windows Server 2012 (64-bit) or later |
| Memory (RAM) | 16 GB |
| Processor (CPU) | Multi-core processor with a minimum of 4 cores |
| Disk Space | 1 TB available local disk space |
All listed requirements must be met before installation.
Important Notes
- These specifications represent the minimum supported configuration.
- Systems with larger data volumes or frequent backup activity may require additional resources.
- Performance depends on workload size, backup schedules, and concurrent system usage.
Meeting minimum requirements ensures compatibility but does not guarantee optimal performance in all environments.
Pre-Installation Checklist
Before installing the Unison App, confirm the following:
- Supported Windows operating system is installed
- At least 16 GB of RAM is available
- Processor has a minimum of 4 CPU cores
- At least 1 TB of free local disk space is available
- System is stable and fully updated
Completing this checklist helps prevent installation issues and reduces the risk of backup interruptions.
Need Help Verifying Your System?
If you are unsure whether your system meets these requirements, verification should be completed before installation.
Support can assist with:
- Confirming system specifications
- Identifying gaps that may affect backup or recovery
- Preparing the environment for reliable operation

FAQs
Can Unison be installed on a virtual machine (VM)?
Unison supports installation on virtual machines if the VM meets minimum OS, CPU, RAM, and disk requirements. The VM must allocate dedicated resources to ensure stable backup performance and reliable recovery operations.
Does Unison require internet access to run backups?
Unison requires internet connectivity to transmit backup data to secure storage, but local backup processes continue independently. Internet availability directly affects offsite backup completion and recovery readiness.
Can Unison run on the same machine as production applications?
Unison can run alongside production applications when minimum system requirements are met. Adequate CPU, RAM, and disk capacity ensure backup operations do not interfere with active workloads.
What happens if system requirements are not met after installation?
If system requirements are not met, Unison may experience slow backups, incomplete jobs, or recovery failures. System resource limitations increase the risk of downtime during restore operations.
Are higher system specifications recommended than the minimum?
Higher system specifications improve backup speed, reduce performance impact, and increase recovery reliability. Environments with large datasets or frequent backups benefit from exceeding minimum requirements.
Does Unison require administrator privileges to install?
Unison installation requires administrator privileges because the application installs system-level services, manages backup processes, and configures secure access to protected directories.
Can Unison run on a machine that is not always powered on?
Unison can run on systems that are periodically powered off, but backups only occur when the machine is online. Continuous uptime improves backup consistency and recovery readiness.
Does Unison require exclusive use of system resources?
Unison does not require exclusive system resources. When minimum requirements are met, Unison operates in the background while allowing normal system workloads to continue.
