Virtualizor

Reinstall a VPS only after protecting its data

Decide when a Virtualizor VPS reinstall is justified, verify an external backup, and check the chosen OS and recovery route before erasing a disk.

Decide whether to reinstall

Use OS Re-Install only after choosing a fresh-OS recovery route and proving a separate backup and restore plan. It removes data from the reinstalled disk.

Even if the panel offers a primary-disk-only reinstall, verify the selected disk and separately preserve every required volume. A same-server snapshot is insufficient as the only recoverable copy; expect to rebuild settings, firewall rules, keys, DNS targets and licences.

Decide whether reinstall is appropriate

SSH is inaccessible but the console works

Diagnose guest network, service and firewall first.

The website application is broken

Review application logs and restore a tested application backup first.

The guest OS is compromised

Contain access and preserve needed evidence, then plan a clean build and credential rotation.

A fresh OS is explicitly required

Verify the external backup, downtime authority and restore plan before reinstalling.

A reinstall is not a general repair button. It removes the existing installation and may destroy evidence that would have explained a fault.

If compromise is suspected, retain incident evidence and rotate exposed credentials through a clean route; reinstalling alone does not establish that other systems are safe.

Prepare a recoverable path

  1. Identify the correct VPS and confirm who owns the data and approves downtime.
  2. Make a current backup outside the VPS; verify that it is readable and includes databases, files, configuration and any required secrets through a secure process.
  3. Record the current OS, IP addresses, application dependencies and recovery steps. Arrange a maintenance window and tell affected users.
  4. Check that the target OS image and required licences are available for this service. If any item is uncertain, stop and ask support before clicking Reinstall.

If this VPS runs MariaDB or PostgreSQL, follow the VPS database backup preflight to check exports, off-VM custody and an isolated restore before reinstalling.

Illustrative go/no-go: if the only backup is on the disk being reinstalled, stop. Obtain a separately held copy and demonstrate that the needed database and files can be read or restored.

Reinstall and verify

In the VPS management panel, choose OS Re-Install, select the intended distribution and version, and set a strong new root password as prompted. Read the confirmation carefully, including any primary-disk-only option. After the task completes, use the console to confirm boot, then update packages, configure access and restore data from the verified backup. Test the application, mail, TLS and monitoring before announcing service recovery.

If anything fails

Do not repeat the reinstall to treat an unexplained boot or network failure. Record the panel task state, timestamp and console output, then contact Novasean support. Customer-managed VPS users own guest data and restore planning; Novasean can investigate platform-side task failure. A managed arrangement may allocate more recovery work, but only its agreed service schedule defines that scope.

Restore and check dependencies

After the new image boots, confirm the expected IP addresses and DNS, apply security updates, restore accounts and applications through the approved backup route, and rotate credentials that were exposed or copied. Test from outside the VPS: web pages, database transactions, scheduled tasks, outbound mail and monitoring. If the service used external DNS or a licence bound to an OS installation, verify those separately. Keep the original backup until the owner has accepted the new service state.

Will secondary disks survive? Virtualizor documents a primary-disk-only option, but do not treat a UI option as a substitute for a backup or assume it is enabled for your VPS. Can support recover data after reinstall? Recovery depends on an existing usable backup; do not assume deleted guest data can be reconstructed.
