# Will I Lose Data When Upgrading?

> Understand what happens to your disk when you upgrade an EDBB VPS and how to keep data safe.

## Upgrade Impact at a Glance

<Info>
  Plan upgrades add CPU, RAM, storage capacity, and traffic allowance—but they do <strong>not</strong> reimage your VPS. Existing partitions remain exactly as they were before the upgrade.

| Resource          | What the upgrade does                                                             | What it doesn’t do                                     |
| ----------------- | --------------------------------------------------------------------------------- | ------------------------------------------------------ |
| vCPU / RAM        | Hot-adds the new allocation (reboot may be advised for the guest OS to detect it) | Doesn’t wipe memory disks or reset configs             |
| Disk size         | Expands the virtual disk capacity                                                 | Doesn’t resize partitions or filesystems automatically |
| Traffic allowance | Boosts monthly quota                                                              | Doesn’t reset usage mid-cycle                          |

## Keeping Data Safe

* Filesystems remain untouched; extend partitions with your preferred tool (`growpart`, `lsblk`, Disk Management) if you want to use the new space.
* Snapshots and qcow2 exports stay available after the upgrade.
* Only a reinstall or manual destructive action removes data—plan normal backups as you would for any production system.

<Note>
  Best practice: take a backup before major changes. Upgrades are non-destructive, but backups protect against unrelated user mistakes or software issues during post-upgrade tuning.
