VPS backup strategy and restore testing
Design a VPS backup strategy with external copies, retention, encryption, RPO, RTO and restore drills that prove your data can actually be recovered.

Define scope, RPO and RTO
Inventory files, databases, configuration, secrets and dependencies. RPO sets acceptable recent data loss; RTO sets acceptable recovery duration. Those choices drive frequency, retention and cost.
| Define scope, RPO and RTO | Question | Design effect |
|---|---|---|
| RPO | How much recent data may be lost? | Copy or replication frequency |
| RTO | How long may recovery take? | Automation and restore speed |
| Retention | How far back must recovery go? | Version count and storage cost |

Create external, verifiable copies
The 3-2-1 approach keeps three copies on two media types with one offsite. Use database-aware procedures: copying active database files without coordination can create an inconsistent result.
rsync -aHAX --delete /srv/data/ backup@example:/backups/server/Run a restore drill
Restore into an isolated environment, verify integrity and run a functional check. Record duration, manual steps, required keys and failures; an archive never restored is an untested assumption.
- 01Select a versionChoose a copy for the simulated incident and verify its checksum or tool-provided integrity.
- 02RebuildPrepare the operating system, dependencies, data and secrets away from production.
- 03ValidateExercise the application and compare actual recovery against RPO and RTO.
Frequently asked questions
Does inetHost include automatic VPS backups?
Cloud VPS plans currently do not include managed automatic backups. Customers must keep external copies and test recovery according to data criticality.
Is a snapshot a backup?
It can be part of a strategy, but should not be the only copy when it shares the platform, account or credentials with the source. Recovery needs isolation and verified versions.
