Protected VPS (high availability)

If your VPS is protected, its page shows the High availability box (and the services list says "High availability: protected").

What it means

Every few minutes the VPS is copied to another server. If the server hosting it fails, the VPS restarts on the other server from its latest copy, with the same IP address: you don't need to change anything (DNS, configuration, firewall).

The box tells you how many minutes of data you can lose at most: the data written after the latest copy. If something very recent is missing after a restart, write to support: the old copy is kept for a few days.

While protection is being set up (the first copy) the box says "being set up": the VPS is protected once the copy is ready.

What it does not protect

• mistakes inside the VPS: deleted files, failed updates, malware. Use snapshots and backups for those;
• data written in the last few minutes before the fault.

A restart is like a reboot after a power cut: services that start at boot come back, the others need to be restarted. If the VPS was in rescue mode or you had opened the files of a backup, it restarts with its own system and those sessions are closed: open them again if you still need them.
