VirtFusion backups copy a server's disk to separate storage on a schedule, so you can roll a VPS back after a mistake, a failed update or a compromise. You set up where backups go, define backup plans, and attach a plan to each server or package.
Before you start
- Backup storage that is not on the same hypervisor as the servers, such as a dedicated backup server reachable over the network.
- Enough space: plan for disk size × number of kept copies, minus any compression.
- Admin access to the VirtFusion admin area.
Add backup storage
- In the admin area open the backups section and add a backup destination.
- Enter the connection details for the backup server (host, port, user and path) as requested.
- Test the connection and save.
Warning: Backups stored on the same machine as the VPS do not protect against hardware failure. Always keep them elsewhere.
Create a VirtFusion backup plan
- Create a new backup plan and name it, for example Daily – 7 copies.
- Set the schedule (daily or weekly) and a time window outside your peak hours.
- Set retention: how many backups to keep before the oldest is removed.
- Select the backup destination and save.
Attach plans to servers
- Assign the plan to an individual server from its settings page, or
- Attach it to a package so every new server gets it, or
- Sell it as a WHMCS configurable option and let the module assign it.
Restore a VPS from a backup
- Open the server and go to its backups list.
- Choose the backup by date and select Restore.
- Confirm. The current disk is replaced, so copy any newer files off first.
- Start the server and check services and data.
Check afterwards
- The first scheduled backup completes and shows a size.
- Do a test restore on a spare server every few months. An untested backup is only a hope.
Troubleshooting
- Backups fail to connect: check firewall rules and credentials between the hypervisor and the backup server.
- Backup storage full: lower retention or add space; failed backups leave you exposed.
- Backups slow down VPSs: move the schedule to quieter hours and stagger servers.
Frequently asked questions
Are VirtFusion backups full or incremental?
It depends on the version and destination type; check the backup settings and documentation for your release.
Can customers restore their own backups?
Yes, if you allow it, customers can restore from their control panel.
Should customers still keep their own backups?
Yes. Off-site, application-level backups (databases, files) are a good second layer.
