# Back up the On-Premise appliance

Two complementary layers: a daily automatic dump inside the appliance, and a snapshot of the data disk on your hypervisor. The first is built in, the second is yours.

## Who does what

|  | Automatic dump | Hypervisor snapshot |
| --- | --- | --- |
| Owner | The appliance, no action needed | You (infrastructure team) |
| Frequency | Daily, around 3:30 a.m. (system time). Caught up at next boot if the VM was off. | Your backup policy |
| Retention | 7 most recent dumps | Your backup policy |
| Location | The appliance data disk | Your backup storage, outside the VM |
| Protects against | Logical corruption, handling error | Loss of the disk, the VM or the host |

The automatic dump is not enough on its own

The dumps sit on the same data disk as the data. If the disk is lost, the dumps are lost with it. Snapshot the data disk from your hypervisor and copy it outside the host.

## Hypervisor snapshot

The appliance has two disks: the system disk, replaced at each [upgrade](https://getnatalia.com/en/documentation/natalia-analytics-on-premise/in-place-upgrade), and the data disk (label `NATALIA_DATA`), which holds everything that matters: CDR, configuration, audit log, dumps. Back up the data disk.

For a consistent snapshot, shut the VM down first, or use your hypervisor's application-consistent snapshot if available. Keep the snapshot outside the host.

## Restore

| Incident | Restore from |
| --- | --- |
| Data disk, VM or host lost | Your hypervisor snapshot: reattach the data disk to an appliance of the same version. |
| Logical corruption | One of the 7 daily dumps, with your integrator partner or Natalia support. |
| Failed migration during an upgrade | Automatic: the appliance restores the pre-upgrade dump by itself. |

Restoring a dump is not self-service: no restore button is exposed in the interface. Contact your integrator partner or [contact@getnatalia.com](mailto:contact@getnatalia.com).
