System Requirements

This guide covers hardware, software, and network requirements for deploying FireBackup Enterprise in your infrastructure.

Hardware Requirements

Minimum Requirements

For development, testing, or small deployments (up to 5 Firebase projects):

Component	CPU	Memory	Storage	Notes
API Server	2 cores	4 GB	20 GB	Handles API requests

PITR Worker	2 cores	4 GB	50 GB	Change capture
PostgreSQL	2 cores	4 GB	100 GB	Primary database
Redis	1 core	2 GB	10 GB	Job queue & cache

Total Minimum: 9 cores, 18 GB RAM, 230 GB storage

Recommended Production

For production deployments (10-50 Firebase projects):

Component	CPU	Memory	Storage	Instances	Notes
API Server	4 cores	8 GB	50 GB	2	Load balanced
Backup Worker	4 cores	8 GB	100 GB	3	Concurrent jobs
PITR Worker	4 cores	8 GB	100 GB	1	Change capture
PostgreSQL	8 cores	32 GB	500 GB SSD	2	Primary + replica
Redis	4 cores	8 GB	50 GB	2	Sentinel HA
Load Balancer	2 cores	2 GB	10 GB	1	Nginx/HAProxy

Total Recommended: 42 cores, 114 GB RAM, 1.06 TB storage

Enterprise Scale

For large deployments (50+ Firebase projects, high throughput):

Component	CPU	Memory	Storage	Instances	Notes
API Server	8 cores	16 GB	100 GB	4+	Horizontal scale
Backup Worker	8 cores	16 GB	200 GB	5+	Based on load
PITR Worker	8 cores	16 GB	200 GB	2+	Per project group
PostgreSQL	16 cores	64 GB	2 TB NVMe	3+	Primary + 2 replicas
Redis Cluster	8 cores	32 GB	100 GB	6	3 masters, 3 replicas

Storage Sizing Guide

Calculate storage requirements based on your data:

API Server Storage:
  OS + Application: 10 GB
  Logs: 10-50 GB (depends on retention)
  Temp files: 20-50 GB

Backup Worker Storage:
  OS + Application: 10 GB
  Temp backup files: 2x largest collection
  Compressed cache: 50-200 GB

PostgreSQL Storage:
  Base: 10 GB
  Per backup record: ~10 KB
  Per PITR window: ~50 KB
  Growth: Plan for 2 years

Example (1000 backups, 100 PITR windows):
  10 GB + (1000 × 10 KB) + (100 × 50 KB) ≈ 25 GB
  With 2-year growth: 75-100 GB recommended
