How to Restore a System from Backups or Snapshots

What this is

This guide explains common recovery paths for a VPS: restore a provider snapshot, or restore files and databases from backups.

What it is for

• Recover from broken updates or configuration mistakes
• Recover after accidental deletion

Prerequisites

• Access to your provider panel (for snapshots)
• Backup files stored safely (off-server recommended)
• Downtime window (restores often require it)

Option A: Restore from provider snapshot (fast rollback)

1. Open provider panel
2. Select the VPS and snapshot
3. Run restore (read warnings: disk will be overwritten)
4. Wait for completion
5. Login via SSH and verify services

Option B: Restore from file backups (more control)

Step 1) Upload/copy backup archive to the server

Example using scp:

scp linux_files_backup.tar.gz USERNAME@YOUR_SERVER_IP:/home/USERNAME/

Step 2) Extract into a safe restore folder

sudo mkdir -p /tmp/restore
sudo tar -xzvf linux_files_backup.tar.gz -C /tmp/restore

Step 3) Copy files into place (carefully)

Example for nginx configs:

sudo cp -a /tmp/restore/etc/nginx /etc/

Warning: Copying configs can overwrite current settings. Review first.

Step 4) Restore databases (separately)

Example MySQL restore:

mysql -u appuser -p appdb < appdb_backup.sql

Final verification checklist

uptime
systemctl --failed
sudo systemctl status nginx --no-pager || true
sudo systemctl status apache2 --no-pager || true
sudo systemctl status mysql --no-pager || true
sudo ss -lntp

Then verify websites and applications from a browser.

Conclusion

Snapshots are the fastest rollback. Backups provide more granular control. The best strategy is to use both.
