Restoring from backup fails


Applies To:

Firmware for GRV-EPIC-PR1

Versions Affected:

All versions


Symptoms:

If your groov EPIC processor has NTP enabled, but no time servers specified, and you create a backup file with this configuration, then when you try to restore this backup, the restore fails.

Workaround:

  1. Make a copy of your backup.
  2. Unzip your backup and edit the file time/time.json.
  3. Do one of the following:
    • If you want to disable NTP, change the serviceEnabled to false.
      {
        "ntp": {
          "serviceEnabled": false
        },
        "zone": {
          "timezone": "Universal"
        }
      
    • ‚ÄčIf you want your groov EPIC processor to make requests to a time server, include at least one time server. The time server can be external or it can be a time server on your local network, if there is one. The following example shows the format to use, and how to add three time servers:
      {
        "ntp": {
          "serviceEnabled": true,
          "timeServers": [
            {
              "peerType": "pool",
              "address": "0.pool.ntp.org"
            },
            {
              "peerType": "pool",
              "address": "1.pool.ntp.org"
            },
            {
              "peerType": "pool",
              "address": "2.pool.ntp.org"
            }
          ]
        },
        "zone": {
          "timezone": "Universal"
        }
      

If you want to create another backup file and prevent this issue (until it's fixed), add a time server (from groov Manage Home page, click System > Time) which points to either an external time server or a time server on your local network, then create a new backup file.
