How to back up and restore data on VPS

Introduction

Data loss on a VPS stops a business instantly. Consequently, a solid backup and restore process is not optional. This guide covers what to back up, which method to use, restore steps, and pitfalls to avoid.

What Is VPS Backup?

A VPS backup copies data, configuration, and software state to a separate location for recovery after damage or loss. Snapshots capture the full disk at a point in time; file-level backups copy only selected directories or databases. Snapshots restore faster after total failure; file-level backups use less storage and suit granular recovery.

What to Back Up

Prioritise these three categories:

• Files and directories: /var/www/, /etc/, /home/, and any custom application paths
• Databases: use mysqldump for MySQL/MariaDB, pg_dump for PostgreSQL, mongodump for MongoDB. Never copy raw database files while the engine runs.
• Configuration files: /etc/nginx/ or /etc/apache2/ configs, firewall rules, and cron definitions

Backup Options: Snapshots vs File-Level

Snapshots suit pre-change protection. HostingB2B VPS Hosting supports snapshot creation from the control panel. However, combine them with off-site backups because providers store snapshots within the same infrastructure. File-level backups using rsync or Duplicati work better for daily schedules and granular recovery.

The 3-2-1 Backup Strategy

When designing your backup workflow, always adhere to the industry-standard 3-2-1 rule:

• 3 copies of data: Keep your production data and at least two distinct backup copies.
• 2 different media types: Store backups on different storage systems (e.g., local VPS disk space and separate cloud object storage) to avoid a single point of failure.
• 1 off-site location: Keep at least one backup copy entirely outside the primary data center infrastructure.

Utilizing HostingB2B snapshots satisfies the redundancy need, but replicating file-level or database backups to a remote region fulfills the vital off-site requirement. See the HostingB2B automated backup guide for step-by-step setup instructions.

Comparison Table

Criterion	Snapshot	File-Level	Best For
Speed	Fast	Moderate	Snapshot
Storage	High	Low	File-level
Restore scope	Full server	Granular	Snapshot: full failure
Off-site	Limited	Flexible	File-level

Common Use Cases by Industry

• iGaming and Fintech: hourly database backups; reconcile records against payment logs; encrypt for PCI DSS
• SaaS: isolate backups per tenant to allow independent restores without affecting other users
• E-commerce: take a snapshot before every plugin update to enable a fast rollback

Enterprise Deployment Considerations

Retain daily backups for seven days, weekly for four weeks, monthly for twelve months. Replicate off-site, encrypt with GPG, and store keys separately. Visit the HostingB2B Knowledgebase for enterprise guidance.

How to Restore VPS Data

From a Snapshot

1. Log in to the control panel and open the VPS snapshot list.
2. Select the snapshot taken before the issue and start the restore.
3. Wait two to ten minutes, then confirm SSH access and application status.

From a File-Level Backup

• Connect via SSH and locate the backup archive or remote directory.
• Extract files: tar -xzf backup.tar.gz -C /var/www/html/ or pull with rsync.
• Fix ownership and permissions, then restart web and application services.

Database Restore

• Create a clean empty database if the original no longer exists.
• Import the dump: mysql -u root -p database_name < backup.sql
• Confirm the import succeeded and restart the application.

Verification Steps

• Run integration tests or visit key application pages
• Query the database to confirm recent records exist
• Review server logs for missing files or permission errors
• Test HTTPS and confirm SSL certificates are valid

Complete all checks before informing users that service has resumed.

Common Pitfalls and Best Practices

• Never copy a live database without a dump tool. Raw file copies corrupt silently.
• Never store all backups on the same server. A single failure removes both.
• Always test a restore before you need it. An untested backup provides no guarantee.
• Always include configuration files. Rebuilding from memory wastes recovery time.
• Monitor backup jobs actively. Automated schedules fail silently without alerting.
