Backup and Restore
Backup and Restore an Edge Device from LEM
UI trigger: LEM -> Edge Lifecycle Management -> Edge Devices -> select device -> Backups -> Make Backup / Restore.
Backups are stored in LEM-managed S3 and accessed via pre-signed URLs (no further auth needed on the URL itself). The backup target on restore can be a different device than the source, which enables configuration cloning across devices.
Step table
Step | Name in Collection | Method | Endpoint | Body / Notes | Output |
|---|---|---|---|---|---|
1 | Make Device Backup | POST | {{LEM_URL}}/api/v1/backup/init-backup?projectId={{project_id}}&deviceId={{edge_device_id}} | No body. Asynchronous - backup runs on the device. | { "code": "200", "content": null } |
2 | List Backups | GET | {{LEM_URL}}/api/v1/backup/list?projectId={{project_id}}&deviceId={{edge_device_id}} | Poll until the new entry appears | List with timestamp and backupType (typically MASTER) |
3 | Get Pre-signed S3 URL to Backup | POST | {{LEM_URL}}/api/v1/backup/get?projectId={{project_id}}&deviceId={{edge_device_id}}&backupType=MASTER×tamp={ts} | -- | Pre-signed S3 GET URL valid 7 days |
4 (optional, cross-tenant) | Save Backup to Pre-signed S3 URL | POST | {{LEM_URL}}/api/v1/backup/put?... | Used only when relocating the .dat to a different S3 location | New pre-signed PUT URL |
5 | Restore from Backup | POST | {{LEM_URL}}/api/v1/backup/init-restore?projectId={{project_id}}&deviceId={{target_edge_device_id}}&backupType=MASTER×tamp={ts} | deviceId query param can target a different device than the source | Restore initiated on target device |
Distinct from "LEM Backup"
This chain backs up a single edge device (/api/v1/backup/...). To back up the LEM instance itself, use Admin Console -> Admin Console Settings -> Backup (/admin/v1/lem-backup/...).
Auth
All calls use X-AuthToken: {{LEM_AdminApiToken}}. The pre-signed S3 URL from step 3 carries SigV4 query params and needs no auth header.
