## Tool

**Kind:** calculator

**Inputs:**

#### Current production database size

**Key:** current_db_gb

**Type:** number

**Default:** 400

**Min:** 10

**Max:** 50000

**Step:** 10

**Unit:** GB

**Help:** Data plus indexes for the production ERP database. Check sys.master_files or your DBA dashboard.

#### Annual growth rate

**Key:** annual_growth_pct

**Type:** slider

**Default:** 18

**Min:** 2

**Max:** 60

**Step:** 1

**Unit:** %

**Help:** Compare this year's size to last year's. Mid-market ERP databases typically grow 10-25% annually.

#### Forecast horizon

**Key:** forecast_years

**Type:** slider

**Default:** 3

**Min:** 1

**Max:** 10

**Step:** 1

**Unit:** years

**Help:** How far out to project. Three to five years matches most hardware and licensing planning cycles.

#### Full-size environment copies

**Key:** environment_copies

**Type:** select

**Default:** 3

**Help:** Each full-size copy of production (test, dev, DR) multiplies the storage you actually pay for.

**Options:**

##### Production only

**Value:** 1

##### Production + test

**Value:** 2

##### Production + test + dev (typical)

**Value:** 3

##### Production + test + dev + DR replica

**Value:** 4

#### All-in storage cost per GB per year

**Key:** storage_cost_per_gb

**Type:** number

**Default:** 8

**Min:** 1

**Max:** 50

**Step:** 0.5

**Unit:** USD/GB/yr

**Help:** Enterprise SAN or cloud block storage including backup capacity typically runs 5-15 USD per GB annually.

#### Data eligible for archiving

**Key:** archive_reduction_pct

**Type:** slider

**Default:** 30

**Min:** 0

**Max:** 70

**Step:** 5

**Unit:** %

**Help:** Closed transactions older than your retention window. ERP databases over 7 years old commonly hold 30-50% archivable data.

**Outputs:**

#### Projected database size at horizon

**Key:** projected_db_gb

**Expr:** round(current_db_gb * pow(1 + annual_growth_pct / 100, forecast_years))

**Format:** number

**Description:** Compound growth applied to the current size, in GB.

**Primary:** true

#### Growth over the forecast period

**Key:** added_gb

**Expr:** projected_db_gb - current_db_gb

**Format:** number

**Description:** New gigabytes accumulated between now and the horizon.

#### Annual storage cost at horizon (all environments)

**Key:** annual_storage_cost_at_horizon

**Expr:** projected_db_gb * environment_copies * storage_cost_per_gb

**Format:** currency

**Description:** What one year of storing the projected database across all full-size copies will cost.

**Primary:** true

#### Archivable data at horizon

**Key:** archivable_gb

**Expr:** round(projected_db_gb * archive_reduction_pct / 100)

**Format:** number

**Description:** Gigabytes that could move to cheap archive storage under your retention policy.

#### Annual savings from archiving

**Key:** annual_archive_savings

**Expr:** archivable_gb * environment_copies * storage_cost_per_gb

**Format:** currency

**Description:** Storage cost avoided each year by archiving eligible data out of every environment copy. Excludes the larger performance and backup-window benefits.

**Disclaimer:** Estimates only. Actual growth depends on transaction volume, module usage, and logging settings; validate the growth rate against at least two years of measured history.

## Content

**Intro:** This free ERP database growth forecaster projects how large your production database will be one to ten years from now, what storing it across every environment copy will cost annually, and how many gigabytes archiving could remove. It is built for DBAs, IT directors, and infrastructure planners running Infor SyteLine, LN, Baan, or other SQL-backed ERP systems who need numbers for hardware refreshes, cloud sizing, or an archiving business case. Enter your current size and observed growth rate and the compound-growth projection, multi-environment cost, and archiving savings appear instantly.

**Sections:**

#### How the forecast works

**Body:** The projection applies compound annual growth to your current database size, because ERP data growth compounds: more customers mean more orders, which mean more shipments, invoices, and ledger lines per year, and index overhead grows with the tables it serves. The cost model then multiplies the projected size by your number of full-size environment copies, which is the step most planning spreadsheets miss; a 400 GB production database with test, dev, and backup copies is really 1.2 TB or more of paid storage. Archiving savings apply your archivable percentage across all copies, since data removed from production disappears from every refresh downstream. All figures use your all-in per-gigabyte rate, so backup capacity is included if your rate is.

#### Benchmarks for growth and archivable share

**Body:** Across mid-market discrete manufacturers we consistently see ERP databases growing 10-25 percent annually, with electronics and high-transaction job shops at the upper end. Growth above 30 percent usually indicates something fixable rather than business volume: verbose audit logging, integration staging tables never purged, or document attachments stored in-database.

**Bullets:**

- ERP databases more than 7 years past go-live typically hold 30-50 percent closed, archivable transaction data
- All-in enterprise storage (SAN or cloud block plus backup capacity) commonly runs 5-15 USD per GB per year
- Each full-size non-production copy adds roughly 100 percent of production storage cost unless masked subsets are used
- Backup windows and index maintenance times grow faster than linearly, so cost is only part of the growth penalty

#### Interpreting the result: when growth becomes a project

**Body:** Storage cost alone rarely justifies action; the projected annual figure matters most as a proxy for the operational pain that arrives with it. When a database crosses roughly 500 GB to 1 TB, most ERP environments hit slower nightly jobs, MRP runs that collide with the business day, backup windows that no longer fit, and test refreshes that take a weekend. If your projected size crosses that band within your forecast horizon, or your archivable share exceeds 30 percent, an archiving and purge initiative will almost certainly return more in performance and administration time than in raw storage dollars. Use the savings figure as the floor of the business case, not the ceiling.

#### How Netray helps you act on the forecast

**Body:** Netray designs and executes archiving and data-lifecycle programs specifically for SyteLine, LN, and Baan schemas, where naive purging breaks referential integrity and costing history. We profile your largest tables, map retention requirements (including the longer horizons aerospace and defense contracts impose), and build archive processes that keep historical data queryable for audits while removing it from the production working set. Where in-database documents or logging drive growth, we re-platform them properly. Clients typically recover 25-45 percent of production database size in the first pass, with correspondingly faster backups, MRP runs, and environment refreshes, and the forecaster's numbers become the before-and-after proof.

**Cta:** Enter two numbers from your DBA dashboard and see what your database will cost you in three years.

**Faq:**

#### How do I find my actual annual growth rate?

**Answer:** Compare database size snapshots twelve months apart; most backup tools and SQL Server's msdb history hold this data already. Take data plus index size, not allocated file size, since pre-grown files mask real growth. If you only have one snapshot, check your oldest full backup's size as a rough baseline. Two or more yearly data points beat any industry assumption, and the slider should reflect your measured figure.

#### Is archiving safe for ERP data, given audit and traceability requirements?

**Answer:** Yes, when done properly. Archiving moves closed transactions to a separate, queryable store rather than deleting them, so audit trails, lot traceability, and as-built history remain retrievable. Aerospace and defense manufacturers routinely archive under retention rules of seven to ten years or longer. The critical requirement is schema-aware tooling that preserves referential integrity; ad hoc DELETE scripts are where archiving horror stories come from.

#### My growth rate is over 30 percent. Is that just business growth?

**Answer:** Possibly, but verify before buying storage. Growth well above transaction-volume growth usually traces to technical causes: audit or debug logging left verbose, integration staging tables that are never purged, document images stored in-database, or index bloat from missing maintenance. Profile your ten largest tables by size and annual delta; in our experience, two or three tables typically account for most excess growth and are fixable without touching business data.
