Running out of disk space is one of the most common causes of application downtime. When a database server fills its disk, transactions fail, data corruption can occur, and recovery is time-consuming. Email servers stop receiving messages. File servers reject uploads. The cost of an emergency storage expansion far exceeds the cost of planning ahead. This calculator helps you estimate your storage needs across all application categories, account for backup overhead, and project growth so you provision infrastructure that lasts without overspending on capacity you do not need.
ERP systems like Odoo consume storage across multiple dimensions. The PostgreSQL database itself grows 1-5 GB per 100 users per year depending on transaction volume. Document attachments (invoices, purchase orders, product images) typically consume 3-5x more space than the database itself. Report archives, audit logs, and email integration add additional overhead. A mid-size Odoo deployment (50-200 users) should plan for 200-500 GB in year one, with 30-40% annual growth. Separating document storage to object storage (S3) can significantly reduce costs while maintaining fast database performance on premium NVMe storage.
Modern infrastructure uses a tiered storage strategy. Block storage (NVMe SSDs, AWS EBS gp3, Azure Premium SSD) delivers low-latency access needed for databases and application code, costing $0.08-0.10/GB/month. Object storage (AWS S3, Azure Blob, GCS) is designed for large volumes of files at $0.02-0.03/GB/month. Archive storage (S3 Glacier, Azure Cool) costs as little as $0.004/GB/month for rarely accessed data. Best practice: keep your database and OS on block storage, move documents and media to object storage, and push old backups to archive storage. This three-tier approach can reduce storage costs by 50-70% compared to keeping everything on block storage.
Backups are essential but often underestimated in storage planning. A 30-day daily backup retention policy effectively doubles your storage requirements. With 90-day retention, total storage can reach 3x your active data. Enterprise compliance requirements may mandate 7-year retention for financial records. Strategies to manage backup storage include incremental backups (only storing changes), compression (typically 40-60% reduction), deduplication, and tiered backup storage where recent backups stay on fast storage and older ones move to cheaper archive tiers. Our calculator accounts for all of these factors in its projections.
