Junos Space Network Management Platform enables you to
back up device configuration information by importing the configuration
file from a device and storing it in Junos Space Platform or on a
remote server. You can use this backup file to recover device configuration
in case of a system failure and also to maintain consistent configuration
across multiple devices. Backing up your device configuration files
is therefore a prerequisite for configuration file management.
Note: Only devices that have been previously discovered by Junos
Space Platform can have their configuration files backed up.
Note:
Use Linux system to store the backup files of a device in Junos Space Network
Management Platform.
The backup function skips over devices that cannot be accessed
by the Junos Space server. On the Job Management page, the state of
a configuration file backup job shows up as Failed in the case of
skipped over devices.
The backup function checks for differences between the configuration
file on the device and the configuration backup file stored in Junos
Space Platform before creating a new version of the configuration
file. If no changes are detected, the device is skipped over. However,
the status is shown as Success on the Job Management page for this
backup configuration job.
Note: The backup function checks for differences between the
configuration file on the device and the configuration backup file
stored in Junos Space Platform. In case the device configuration has
not changed, but you edit its configuration file in Junos Space Platform
and then back up the configuration from the device, a new version
is created. The first backup file is Version 1, the edited configuration
file is Version 2, and the second backup file is Version 3.
When you back up a configuration file, an audit log entry is
automatically generated. From the audit log entry, you can identify
the user who initiated the backup operation, the IP address from which
this task was initiated, and so on.
Note: In the case of an SRX Series device with logical system
(LSYS), configuration file backup is supported only on the root device.
To back up configuration files from one or more devices
to Junos Space Platform:
- On the Junos Space Platform UI, select Configuration
Files > Config Files Management.
The Config Files Management page appears.
- Click the Backup Configuration
Files icon.
The Backup Configuration Files page appears, displaying the
following information for all the devices managed by Junos Space Platform:
Host Name: Name of the device whose configuration file
you are backing up
Device Alias: Value of the Device Alias custom label for
the device
Domain: Domain to which the device belongs
IP Address: IP address of the device
Platform: Device platform
Serial Number: Serial number of the device
Software Version: Operating system firmware version running
on the device
Because the table displays one device (record) per row, a single
page might not be sufficient to list all your devices.
The left side of the status bar at the bottom of the page shows
which page is currently displayed and the total number of pages of
records. It also provides controls for navigating from page to page
and refreshing them. The right side of the status bar indicates the
number of records currently displayed and the total number of records.
- From the table, select the devices whose configurations
you want to back up, by using one of the following selection modes—manually,
on the basis of tags, or on the basis of domains. These options are
mutually exclusive. If you select one, the others are disabled.
Note: By default, the Select by Device option button
is selected and the complete list of devices is displayed.
If you want to back up the configuration of all devices,
select the Select All across Pages check box.
To select devices manually:
- Click the Select by Device option and select
the devices whose configurations you want to back up.
The Select Devices status bar shows the total number of devices
that you selected, dynamically updating as you select.
- (Optional) To back up all the devices, select the check
box in the column header next to the Host Name column.
To select devices on the basis of tags:
- Click the Select by Tags option.
The Select by tags list is activated.
- Click the arrow on the Select by tags list.
A list of tags defined for devices in Junos Space Platform appears,
displaying two categories of tags—Public and Private.
Note: If no tags are displayed, then it means that none of the
devices are associated with any tag. You need to tag the devices first
on the Device Management page before you can use the Select by
Tags option. For more information about tagging, see Tagging an Object.
- To select tags, perform one of the following actions:
Select the check boxes next to the tag names to select
the tags and click OK.
To search for a specific tag, enter the first few letters
of the tag name in the Select by Tags field to the left
of the OK button. If a match is found, a suggestion is
made; you can select it and click OK.
The total number of devices associated with the selected tags
appears just above the device display table. For example, if there
are six devices associated with the selected tags, then 6 items selected is displayed.
The selected tags appear next to the Tags Selected label. An [X] icon appears after each tag name. Click the [X] icon
to clear any tag from the list. The device count decrements accordingly.
To select devices on the basis of domains:
- Click the Select by Domains option.
The Select by domains list is activated.
- Click the arrow on the Select by domains list.
The list of domains appears. Only the domains that you have
access to are available for selection.
- Select the check boxes next to the domain names to select
the desired domains and click OK.
The total number of devices associated with the selected domains
appears just above the device display table.
The selected domains appear next to the Domain(s) Selected label. An [X] icon appears after each domain name. Click the [X]
icon to clear any domain from the list. The device count decrements
accordingly.

Junos Space Platform uses Secure Copy Protocol to back up the
configuration file to the specified folder in the remote server. The
name of the file is in the following format:
<device_name>_<device_ip>_<version>_<timestamp>.conf.gz
Here, device_name is the name of the device, device_ip is the IP address of the device, version is the configuration file version and timestamp is the
date and time the configuration file is backed up.
- (Optional) To schedule a time for backup of configuration
files, select the Schedule at a later time check box, and
use the calendar icon and the drop-down list, to specify the date
and the time respectively.
If you do not select the Schedule at a Later Time check box, the configuration files are backed up as soon as you
click the Backup button on the Backup Config Files page.
Note: If a backup is already scheduled for later using password
mode, in order to use Space Key or Custom Key, you must cancel the
existing scheduled task and reschedule it using the authentication
mode of your choice.
If a backup is already scheduled for later using Custom Key
and if the key has changed, you must cancel the existing scheduled
task and reschedule it using the updated key.
