Cloud backup for servers and applications

Cloud backup for VPS, cloud servers, applications and databases: RPO, RTO, retention, off-server copies, restore tests and disaster planning.

Hub

Cloud backup is not just a file copy. For servers, applications and databases, consistency, retention, RPO, RTO, off-server copies, restore tests and a practical emergency procedure matter.

Cloud migration Plan backup before switching the service. Cloud server Choose an environment with room for copies and restore. Backup monitoring Alert missing copies and job failures. Docker Protect volumes, databases and container configuration. Business mail Check mail DNS and systems after changes. DNS audit Verify domains after service restore.

Backup for cloud servers, VPS and applications

A good backup answers two questions: how much data can be lost and how quickly the service must return. A website, shop database and file-heavy application require different backup plans.

Elements of a useful backup plan

RPO and RTO

RPO defines acceptable data loss and RTO defines acceptable recovery time.

Off-server copy

A backup on the same server does not protect against machine loss, administrator mistakes or encrypted data.

Database consistency

Databases need logical dumps, consistent snapshots or a write-freeze procedure.

Restore test

A backup without restore testing is only a hope, not a recovery procedure.

Backup rollout order

  1. List critical data. Separate application code from databases, user files, configuration, certificates and secrets.
  2. Set the schedule. Match backup frequency with RPO and the pace of data changes.
  3. Plan retention. Keep multiple points in time so you can recover before a logical error or infection.
  4. Monitor jobs. A missing backup should alert automatically.
  5. Test restore. Restore the service in a separate environment and record the real recovery time.

What should be backed up?

  • Databases, user uploads and application files.
  • Configuration, certificates, secrets and deployment files.
  • Container volumes and Docker Compose or Kubernetes manifests.
  • Mail data and DNS-related configuration where relevant.
  • Documentation of restore steps and administrator access.
