General

Device Network Settings

Item Description
a WAN With default settings, WAN rules apply if a device is restoring from or backing up to a destination with a routable IP address. Override the default settings by specifying Network overrides (h).
b LAN With default settings, LAN rules apply if a device is restoring from or backing up to a destination with a non-routable IP address. Override the default settings by specifying Network overrides (h).
c Limit sending rate when away to

Bandwidth setting when you are not using your computer. Backup and restore will be slower at lower bandwidth settings. Setting rate limits to None means no throttling takes place.
Note: In Linux, the CrashPlan app always uses the "away" setting

 

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 enterprise 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.
d Limit sending rate when present to
Windows and Mac only
Bandwidth setting when you are working at your computer. Backup and restore will be slower at lower bandwidth settings.
e Sending message buffer size Size of outbound buffer for WAN and LAN. Expert users only!
f Receiving message buffer size Size of inbound buffer for WAN and LAN. Expert users only!
g TCP Packet QoS (Advanced - must have QoS capable router configured) Choose the TCP Packet quality from the list: Low, Normal, Reliability, Throughput or specify a DSCP value.
h Network overrides
CrashPlan PROe only

Override the default WAN and LAN definition and add your own network ranges. For example, specify your VPN network range to always use WAN settings in order to throttle backups and restores occurring over the VPN.

Use Classless Inter-Domain Routing (CIDR) notation to enter network overrides:

  • IPv4 example: 192.168.1.0/24
  • IPv6 example: 2001:db8::/32
