NinjaOne Backup — Error 318: Network Storage Not Defined
Audience: T1 / T2 Use when: Backup pre-flight fails with "Error 318: NAS_NOT_DEFINED."
What This Error Means
No default network storage device has been configured at the organization, location, or device level in NinjaOne. The backup plan is set to use local storage, but NinjaOne doesn't know where to send the data.
Error 318 is similar to Error 303, with a subtle difference:
| Error | Trigger |
|---|---|
| 303 | A NAS path was configured but is missing/invalid on the device |
| 318 | No NAS storage device is defined anywhere — no path has ever been set |
Step 1 — Check Organization-Level Storage Location
- NinjaOne → Administration → Organizations → select the client org
- Click into org → left sidebar → Backup → Storage Locations
- Is there a storage location listed? If not: create one (Step 2)
Step 2 — Create a Storage Location
If no storage location exists at all:
-
Organization → Backup → Storage Locations → + Add
-
Fill in:
- Name: NAS hostname (e.g.,
DENTAL-NAS01) - Path:
\\NAS-HOSTNAME\backups\ninjaone - Credentials:
dtcbackupservice account
- Name: NAS hostname (e.g.,
-
Save
Step 3 — Set a Default Storage Location
After creating the storage location, it must be set as the default for the org or the specific device:
Org-level default: Organization → Backup → Storage Locations → click the location → Set as Default
Device-level override (if different NAS per device): NinjaOne → device → Backup → Edit plan → Local Storage → select the storage location explicitly
Step 4 — Verify and Trigger
After setting the storage location:
- Trigger a manual backup run
- Error 318 should not recur — if it does, check that the storage location is actually linked to the backup plan (not just defined at org level but not selected in the plan)
