System backup / restore

  • All backups must be restored on the exact same ThingPark All-in-One version.
  • ThingPark All-In-One integrates a full backup intended to restore the exact server configuration later on in case of a problem. This is a heavy backup that takes time and resources.
  • ThingPark All-In-One also integrates a data-only backup intended to regularly back up essential data (every hour). This is a very lightweight backup that does not use write IO. It can be executed through the UI (similar to a full backup) or from an external backup server that can send an HTTP POST request to ThingPark All-In-One.
  • By using these two backups, it is possible to restore a ThingPark All-In-One platform with minimal impact on data lost.

Full backup​

  • It is necessary to regularly create a backup archive of your gateway:

    • Before / after node-red flow changes
    • After new device creations
    • Before / after LRR modifications (via Suplog)
    • Before / after system upgrades, to support potential rollback situations

  • To create a backup file :

    • Go to Advanced Management

    • Click FULL BACKUP, then click BACKUP again on the popup

  • After the backup is executed with success, a persistent link is generated :

    • it indicates the age of the last backup
    • it allows you to download the file later-on, but it is highly recommended to save the backup file in an alternative storage location

  • The backup file consists of :

    • LRC database (FDB_lora),
    • Node-Red data folder (flows, credentials),
    • TPE-All-in-One (TAO) data folder (secret key),
    • A complete LRR backup (specific LRR procedure), including the network, configuration changes provided through Suplog
    • TAO release version file
note

Passwords are not included in the archive.

Data only backup​

  • The backup file consists of:
    • Living data of LRC database (FDB_lora [a,b,l,k]),
    • Node-Red data folder (flows, credentials),
    • TPE-All-in-One (TAO) data folder (secret key).

Data only backup through the UI​

  • To create a data-only file through the UI

    • Go to Advanced Management:

    • Click DATA-ONLY BACKUP.

  • After the backup is executed with success, the file is directly downloaded on the browser

Data only backup through the HTTP POST request​

  • You must first copy the HTTP POST URL from the UI

  • On an external backup server, you can execute the POST request, and the resulting content is a tar.gz file.

[root@localhost /]# filename=tao-data-only-backup-$(date +"%Y-%m-%d-%H-%M").tar.gz
[root@localhost /]# curl -X POST http://10.100.30.235:1323/rest/v1/system/backup-restore/data-backup?backup-key=2grRfjcytllA7N2S --output $filename

System restore​

  • Restore can only be executed on the same TAO version and the same hardware model (full restoration of LRR requires the same hardware model).

  • It allows you for example to rebuild the ThingPark All-in-one server after a hardware failure

    • install the same TAO version on an identical hardware model
    • restore the full backup archive content on that gateway
    • restore the latest data-only backup content on that gateway

  • Be careful, as the network configuration is restored, you might lose your gateway, it is then recommended to make sure that the gateway is correctly configured (identically as the backup).

  • A complete restore takes around 3mn

  • To restore a backup :

    • Go to "Advanced Management"

    • Click on the Restore button

      • On the popup
      • Click on "I understand the consequences of the restore"
      • Click on the and pickup your full backup archive
      • Click on the and pickup your data-only backup archive

    • During restoration, a waiting screen is displayed, and the GUI is locked:

    • Any attempt to navigate is blocked, all new login will be redirected to this same page.

    • After restoration, all required services are restarted and the user can navigate again.
