Server Management

This guide covers day-to-day VPS management including backups, monitoring, firewall configuration, scaling, and disaster recovery.

Backups

Automated Backups

Every InteSys VPS includes automated daily backups with a minimum 3-day retention period. Backups are stored in a separate fault domain from your primary server.

Feature Standard Extended
Frequency Daily Daily + Hourly snapshots
Retention 3 days 7–30 days (configurable)
Storage location Separate fault domain Cross-region replication
Restore time < 15 minutes < 15 minutes

Manual Snapshots

Create on-demand snapshots before major changes:

  1. Go to Services > Your VPS > Snapshots
  2. Click Create Snapshot
  3. Add a descriptive label (e.g., "pre-upgrade-2026-03")

Snapshot Before Upgrades

Always take a manual snapshot before OS upgrades, kernel updates, or major application deployments. Rollback takes seconds.

Restoring from Backup

  1. Navigate to Services > Your VPS > Backups
  2. Select the backup point you want to restore
  3. Choose Restore to existing server or Restore to new server
  4. Confirm the operation

Restore Overwrites Data

Restoring to the existing server replaces all current data. If you need to recover specific files, restore to a new temporary server and copy files manually.

Monitoring

Built-in Monitoring

The client portal provides real-time metrics for:

  • CPU utilization — Usage percentage across all vCPUs
  • Memory usage — Total, used, cached, and available
  • Disk I/O — Read/write throughput and IOPS
  • Network traffic — Inbound and outbound bandwidth
  • Disk space — Usage per volume

Alerting

Configure alerts under Services > Your VPS > Alerts:

  • CPU usage above threshold for sustained period
  • Memory usage exceeding defined limit
  • Disk space below minimum free threshold
  • Network traffic anomalies

Alerts are delivered via email and optionally via webhook to your monitoring stack.

External Monitoring Integration

For advanced monitoring, integrate with your preferred observability platform:

# Example: Install Prometheus Node Exporter
wget https://github.com/prometheus/node_exporter/releases/download/v1.8.2/node_exporter-1.8.2.linux-amd64.tar.gz
tar xzf node_exporter-1.8.2.linux-amd64.tar.gz
sudo mv node_exporter-1.8.2.linux-amd64/node_exporter /usr/local/bin/

Firewall Configuration

InteSys Network Firewall

In addition to your OS-level firewall, InteSys provides a network-level firewall managed through the portal:

  1. Go to Services > Your VPS > Firewall
  2. Define inbound rules (allow/deny by port, protocol, and source IP)
  3. Apply changes — rules take effect within 30 seconds

Default Policy

The default policy allows all outbound traffic and blocks all inbound traffic except SSH (port 22). Add rules for your application ports explicitly.

Scaling

Vertical Scaling

Increase CPU, RAM, or storage for your existing VPS:

  1. Navigate to Services > Your VPS > Resize
  2. Select the new resource configuration
  3. Confirm — most upgrades apply with a brief reboot (under 60 seconds)

Horizontal Scaling

Deploy additional VPS instances and distribute traffic using:

  • Load balancing via InteSys network infrastructure
  • DNS round-robin for simple distribution
  • Application-level clustering (e.g., Kubernetes, Docker Swarm)

Disaster Recovery

Recovery Point Objective (RPO)

With standard daily backups, the worst-case data loss is 24 hours. Enable hourly snapshots (Extended plan) to reduce RPO to 1 hour.

Recovery Time Objective (RTO)

Scenario Estimated RTO
Restore from backup < 15 minutes
Rebuild from snapshot < 5 minutes
Cross-region failover < 30 minutes

Cross-Region Replication

For mission-critical workloads, enable cross-region backup replication to maintain copies of your data in a geographically separate datacenter. Contact support to configure this feature.
