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 |
Hypervisor snapshot
The appliance has two disks: the system disk, replaced at each 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 [email protected].
