Support SLAs, backups and recovery
Reliability language is only useful when it explains what happens during a real incident. Response targets, backup copies and recovery claims need scope, ownership and a tested procedure.

01
A support SLA defines a response commitment
A support SLA should state which incidents qualify, how severity is determined, when the clock runs and what initial response means. It should distinguish office-hours support from out-of-hours coverage and explain the channel customers must use. A headline response time without these definitions is difficult to apply during an incident.
Response is not the same as resolution. Infrastructure faults, application defects and external dependencies require different investigation paths. The agreement should make the first ownership step predictable while leaving room for the technical diagnosis to determine the resolution work.
02
Backups are inputs to recovery
A successful backup job proves that data was written somewhere. It does not prove that the correct data can be restored within the period the business expects. Useful backup information includes scope, frequency, retention, storage separation, access, monitoring and the way restoration is requested and performed.
Applications often combine databases, uploaded files, generated assets, search indexes and external systems. Recovery planning should identify which elements are authoritative, which can be rebuilt and which need a coordinated point in time.
- What data and configuration are included in backup scope?
- How frequently are copies made and how long are they retained?
- Who can request, approve and perform a restoration?
- How is restored data validated against application behaviour?
03
RPO and RTO need an operating plan
A recovery point objective describes the maximum targeted data-loss window. A recovery time objective describes the targeted time to restore a service. Both depend on architecture, backup design, incident type and the decisions made during recovery. They should not appear as isolated marketing numbers.
If exact objectives are important, connect them to the systems they cover, exclusions, test method, escalation process and commercial agreement. A realistic plan may use different objectives for a transactional database, media files and a rebuildable search index.
04
Test the relationship, not only the tooling
Incidents reveal communication problems as quickly as technical ones. Teams need to know who declares severity, where updates appear, who can make application decisions and how infrastructure engineers obtain the context required to help. Practice or review the process before it is needed.
The strongest reliability arrangement combines sound infrastructure with clear responsibility. Your application team owns business behaviour and release decisions. The hosting partner operates the managed platform and leads the infrastructure work within the agreed scope. Recovery succeeds when those responsibilities connect without delay.
Reliability questions to resolve in advance
- Severity definitions, response targets, support channels and coverage hours.
- The difference between initial response, investigation and resolution.
- Backup scope, frequency, retention, monitoring and restoration ownership.
- Application-specific recovery priorities and validation steps.
- Communication and decision ownership during an incident.
