Code42 Support

Configuring Device Networks

Applies to:
  • Code42 CrashPlan (previously CrashPlan PROe)

Overview

Code42 server version 5.4 introduces the Device Networks screen in the administration console, which enables administrators to configure sending limits for device backups based on the device location. Configuring network-based device backup rates has many advantages, including:

  • The ability to finely control bandwidth use for any combination of device location, day, and time.
  • The ability to prevent traveling users from saturating Internet connections with CrashPlan backup activity when visiting locations with low available bandwidth.
  • The ability to configure sending limits not tied to organizational hierarchy.

In Code42 server versions 5.2 and 5.3, network-based device backup rates can be configured via the Code42 API.

Considerations

  • Device Networks settings are only available to users with SYSADMIN permissions and Code42 environments with an on-premises master server.
  • Enabling network-based backup rates overrides existing settings defined in the Settings > Device Backup > Network section of the administration console and apply globally to your entire Code42 environment.
  • The sending limits referenced throughout this article apply only to device backup. Sending limits do not apply to devices restoring files.
  • Network-based backup rates require CrashPlan app version 4.6 or later (4.x-series) or 5.2 or later (5.x-series). To enable scheduled sending limits, CrashPlan app version 4.7 or later (4.x-series) or 5.3 or later (5.x-series) is required. Older versions of the CrashPlan app will use the settings that were in place before network-based backup rates were enabled. However, you will be unable to edit the old settings via the administration console.
Network Sites Disabled By Default
Network-based device backup rates are disabled at a global level by default. To enable these sending limits, you must enable both the individual network site and the global setting (explained below in Step 3: Enable Network Sites).

Before You Begin

The Device Networks screen uses the concept of network sites to define device sending limits. A network site is a specific IP address, IP range, or subnet to which a device connects. This indicates the device location. For example, the network within a company's corporate headquarters could be defined as one network site, and the network at a remote office could be defined as another network site.

  • Identify the sites for which you want to define a maximum device sending rate. Obtain the IP addresses or subnet for each site.
  • Determine the desired maximum sending rate in Mbps (megabits per second) for:
    • Each device location
    • When users are present and when they are away from their devices
    • Peak and non-peak business hours (optional)
      Consult your network administrator for assistance determining the appropriate maximum sending rates for your environment.

Configuring Device Networks

Step 1: Define Default Sending Limits

Because it would be highly impractical (and nearly impossible) to pre-define sending rates for every possible device IP address, the default sending rates apply to devices connecting from locations not specifically defined in a network site (see step 2 below). Practically speaking, this means if you define sending limits for all known company offices, a user device connecting to the Internet from a home or public network would use the default sending limits, because the device's IP address won't match any defined network sites.

To set the default sending limits:

  1. Sign in to the administration console.
  2. Select Settings > Device Networks.
  3. Select Edit Default.
  4. Select Away and Present sending limits for both WAN and LAN connections:
    • Away defines the maximum data transfer rate when the user is away from the device.
      Linux devices always use the away setting.
    • Present defines the maximum data transfer rate when the user is present at the device.
  5. Click Save.

Edit Default Network Site Sending Limits

Step 2: Create A New Network Site

Repeat the steps below for each group of IP addresses requiring specific device sending limits.

  1. From the administration console, select Settings > Device Networks.
  2. Select Create New Site.
    The Create Network Site screen appears.
  3. Enter a site name.
  4. Enter an IP address or range.
    This defines the specific IP address, IP range (in CIDR notation), or subnet to which a user device connects. Both IPv4 and IPv6 addresses are supported.
  5. Click Add.
  6. Repeat steps 4 and 5 as necessary to add additional IP addresses to the site.
    To remove an IP address, hover over it and click the "x" icon Delete Icon.
  7. Enter a Site description (optional).
  8. Choose Standard or Scheduled sending limits:
    • Standard sending limits apply the same values at all times.
    • Scheduled sending limits enable you to specify different sending limits for peak and non-peak business hours. See Define Schedules steps below for more details.
  9. Select Away and Present sending limits:
    • Away defines the maximum data transfer rate when the user is away from the device.
      Linux devices always use the away setting.
    • Present defines the maximum data transfer rate when the user is present at the device.
      Minimum Recommended Sending Limits
      When setting network sending limits, do not set a rate lower than 0.10 Mbps or 100 Kbps. Rates lower than 0.10 Mbps can prevent devices from communicating with the Code42 server, which can stop backups and future configuration changes. To stop backup entirely, do not adjust sending limits. Instead, you can pause backup or only allow backups at specified times.
  10. Click Enable Network Site (optional). Enabling a network site enforces the defined sending rates. Disabling a network site allows you to save the defined settings but not apply the values right now.
    When editing an existing network site, the Enable Network Site toggle appears at the top of the page.
  11. Click Add Site.

Create Network Site

Define Schedules (Optional)

Requires CrashPlan app version 4.7 or later (4.x-series) or 5.3 or later (5.x-series).

Scheduled sending limits enable you to define schedules with different sending limits for peak and non-peak times. This is useful for limiting backup traffic when specific networks are busy with higher priority network activity.

To define peak and non-peak schedules:

  1. In the Sending Limits section, select Scheduled.
  2. Select days of the week to be included in the peak schedule.
  3. Select start and end times for each day.
    Scheduling is based on each device’s local time.
  4. Select Away and Present sending limits for peak hours.
  5. Select Away and Present sending limits for non-peak hours.

Step 3: Enable Network Sites

The administration console enables you to create and configure network sites before applying the sending limits to devices in your Code42 environment. Once you have completed the network sites setup, you must enable them globally:

  1. From the administration console, select Settings > Device Networks.
  2. Click Network-based device backup rates to turn them On.
  3. To apply any configured scheduled sending limits, click Schedule sending limits to turn them On.

Enable Network Sites

Modifying Network Sites

Once you have created network sites, follow the steps in the sections below to modify, sort, or delete network sites.

Network Sites List

Editing A Network Site

To edit an existing network site:

  1. From the administration console, select Settings > Device Networks.
  2. Click anywhere in the row of an existing site.
    The Network Site Details screen appears.
  3. Edit values as necessary.
  4. Click Update Site.

Sorting Network Sites

The CrashPlan app applies the sending rate for the first match it finds in the list of network sites. If the device matches more than one definition, it uses the configuration for whichever site is listed first.

To sort network sites:

  1. From the administration console, select Settings > Device Networks.
  2. Hover over the row for a network site.
  3. Click the arrow icon Sort Icon on the far left.
  4. Use the arrows to adjust the sort order, or manually enter a number in Move to.
  5. Click Apply.

Deleting A Network Site

To remove an existing network site:

  1. From the administration console, select Settings > Device Networks.
  2. Hover over the row of the network site you want to remove.
  3. Click the "x" icon Delete Icon.
    The Delete Network Site confirmation message appears.
  4. Click OK.
