Reducing ERP and Production Downtime for Small Manufacturers

Why ERP downtime hits manufacturers harder than most

In an office-only business, an ERP outage means delayed invoicing or a frustrating afternoon. On a production floor, it can mean a stopped line, an inability to record what's being produced, and a shipping department that can't confirm what's ready to go out the door. The cost of downtime scales directly with how tightly the ERP is woven into daily operations, and for most small manufacturers, that's very tightly indeed.

Building redundancy where it counts

Redundancy doesn't mean duplicating everything; it means identifying the specific single points of failure that would stop the ERP and addressing the ones that matter most. For an on-premise ERP, that typically starts with the server hosting it: redundant power supplies, RAID-protected storage, and, where the budget allows, a secondary host that can take over if the primary fails.

Network redundancy matters just as much as server redundancy. A single internet connection or a single switch feeding the server room is a common, avoidable single point of failure, particularly for cloud-hosted ERP systems where the whole plant depends on that connection staying up.

• Redundant power (UPS, and generator for longer outages where justified)
• RAID-protected or otherwise redundant storage for the ERP database
• A secondary internet connection with automatic failover for cloud ERP access
• Redundant core switching so a single switch failure doesn't take down the plant network

Setting real recovery objectives

Every backup and disaster recovery plan should answer two questions in specific numbers, not vague assurances: how much data can we afford to lose (recovery point objective), and how long can we afford to be down (recovery time objective). For an ERP running production, both numbers tend to be tighter than for general office file storage.

Once those numbers are defined, backup frequency and recovery procedures should be built to actually meet them, then tested. A nightly backup with an assumed four-hour recovery time is only meaningful if a real restore has actually been timed and confirmed, not estimated.

1. Define an acceptable recovery point objective (how much data loss is tolerable) for the ERP database
2. Define an acceptable recovery time objective (how long production can tolerate an outage)
3. Configure backup frequency and technology to meet those objectives
4. Test a full restore on a schedule and record the actual time it took
5. Adjust the plan if testing reveals the real numbers don't meet the targets

Change windows that respect production schedules

Patching and updates are a leading, preventable cause of unplanned ERP downtime when they're pushed out during production hours without warning. A defined change window, agreed with production leadership and scheduled around shift patterns, lets updates happen when a brief disruption is tolerable rather than when it costs the most.

This matters just as much for the underlying server, SQL, and networking infrastructure as it does for the ERP application itself; all of it should follow the same coordinated schedule.

Coordinating with the ERP vendor

Your IT provider manages the infrastructure the ERP runs on; the ERP vendor owns the application itself and its licensing. When something goes wrong, knowing quickly which side of that line the problem sits on saves hours. A managed IT provider with an established relationship and case history with your ERP vendor can often get a case triaged faster than a one-off call from whoever happens to answer the phone that day.

This distinction, infrastructure support versus vendor application support, matters enough that we address it directly with every manufacturing client so nobody is confused about who owns what during an incident.

Where this connects to broader manufacturing IT

ERP resilience doesn't exist in isolation from the rest of a manufacturer's IT environment. Firms running any level of connected shop-floor equipment should also review our article on OT and IT convergence for small industrial operations, since network segmentation reduces the chance that a security incident on the office side takes down production systems as well. Manufacturers that also supply the mining sector should see our guide on IT support for mining supply and service contractors in Sudbury for the connectivity and compliance angle.
