Backup and DR Service generates many logs that are useful for troubleshooting.
This section describes the log types and how they work together.
Download logs from the backup/recovery appliance
You can use the Downloads tab in the Logs section of the
Appliance Configuration to download log files. Each downloaded log is
bundled as a zip file in the download folder. You can then extract the
downloaded log files and use a text editor to view the contents of each log.
Use these instructions to download logs from backup/recovery appliances:
In the management console, select Manage>Appliances.
Right-click the appliance and select Configure Appliance to open the
Appliance Configuration page.
From the left panel, select Configuration>Logs.
The Logs page appears, listing the logs that you can download.
By default, the backup/recovery appliance downloads logs from the past 3 days (starting with the current date).
To specify a particular date range from which you want to download logs,
click the calendar icon and select a start date in the From Date field and
an end date in the To Date fields.
Check the boxes of the logs to download. See Log types are detailed in what you can learn from logs.
You can also select ALL in the upper right corner to download all logs.
Click Download Logs.
You can also view the event logs
created on backup/recovery appliances in Cloud Logging by using the Google Cloud console
and the gcloud CLI CLI.
Download agent logs
Backup and DR agent logs are a great tool for troubleshooting. You don't need
access to the host where the agent is running to download the agent logs; you
can use the same method used to download backup/recovery appliance logs.
Use these instructions to download agent logs from one of your hosts:
In the management console, select Manage>Appliances.
Right-click the appliance and select Configure Appliance to open
the Appliance Configuration page.
From the left panel, select Configuration>Logs.
The Logs page appears, listing the logs that you can download.
By default, the backup/recovery appliance downloads logs from the past three
days (starting with the current date).
To specify a particular date range from which you want to download logs,
click the calendar icon and select a start date in the From Date field
and an end date in the To Date fields.
Select the agent checkbox from log types.
To download logs from the Backup and DR agent installed on a specific host,
click the Select Hosts drop-down and choose from the list of available
hosts.
Click Download Logs.
