# Server and backup

> Besides the server and backup we also maintain the databases themselves: we monitor referential integrity, transaction logs, the event log and the event history tables. Clients with maintenance get a better SLA response, so problems are solved before they become downtime.

## What maintenance covers

- **technical database maintenance,**
- checking **referential integrity**, so data across tables stays consistent,
- monitoring **transaction logs**,
- monitoring the **event log**,
- monitoring **event history tables**, which grow over time and slow the system down,
- the state of servers and disks and the execution and correctness of backups,
- business continuity planning and the recovery procedure, so it is known in advance, avoiding ad hoc solutions at the moment of failure.

## Better SLA response

Clients with maintenance have a better SLA response than those without it. That is why problems are often noticed and solved before users see them.

## Key points

- Technical database maintenance
- Referential integrity
- Transaction logs and event log
- Event history tables
- Better SLA response with maintenance
