WOL section changed as per the Backup with DAR page:
 
  
===Use WOL to power on Workstation===

I  wanted to make a suggestion that the section describing backup to USB drive should emphasize that the USB drive will be auto mounted.
Wake On Lan can be used to power up the backup target workstation before starting the backup.

In other words, make sure that the USB drive is unmounted when configuring the Workstation Backup. Otherwise it will say that it cannot find the removable device.

Thanks.
  
To use WOL there simply needs to be a new variable added to the backupwk section of the configuration database, nothing else is required. This variable holds the MAC address of the target workstation, if the MAC address is 00:4E:89:F5:FD:2B use:

db configuration setprop backupwk SmbHostMAC 00:4E:89:F5:FD:2B
 
 
 
There is also the ability to specify how long to wait between the WOL packet being sent and attempting to start the backup process. The default wait time is 300 seconds, this can be varied via another configuration database setting. It is recommended to not set the wait period below 300 seconds. To set the wait time to 600 seconds:
 
 
 
db configuration setprop backupwk SmbHostDelay 600
 
 
 
The target system must support, and be set up to respond to, the WOL "magic packets". The network infrastructure must also support WOL packets. WOL should work across the local network without problem. WOL packets are not routeable so it won't work across the internet without additional support from hardware and/or software such as a VPN tunnel. Getting WOL to work across the internet is beyond the scope of this documentation but there are plenty of resources available elsewhere. Most wireless connected devices do not work with WOL.  
 
 
 
Note that there is no checking that the supplied MAC address is the correct one for the IP address/hostname of the target workstation. MAC address's are effectively static but IP address's/hostnames can change particularly if the target gets its IP address via DHCP. It is quite possible to have the correct target woken up and be ready but the backup to fail because the IP address has changed. However SME's DHCP server very rarely changes the IP address of a given MAC address.
 
 
 
To stop using WOL simply delete the SmbHostMAC variable:
 
 
 
db configuration delprop backupwk SmbHostMAC
 
 
 
and to be tidy if the optional delay parameter has been set:
 
 
 
  db configuration delprop backupwk SmbHostDelay

User: StephenHodgman I wanted to make a suggestion that the section describing backup to USB drive should emphasize that the USB drive will be auto mounted. In other words, make sure that the USB drive is unmounted when configuring the Workstation Backup. Otherwise it will say that it cannot find the removable device. Thanks.

Please can you propose to write the chapter you want to modified, if no objections i will edit the manual....sorry but i'm a french user :) --Stephdl (talk) 10:47, 18 January 2014 (MST)
