Using Crashplan Backup on QNAP Turbo NAS

Looking at the applications available for my QNAP NAS, I saw there was a Crashplan server so I decided to try it out as a common backup client for my Windows and Linux PC's. Will probably stick with SSH / Rsync as well on Linux, but I am always quite keen to try out new backup software. And this one is the free version, which works fine for my needs.

Linux Client

On my CentOS box, I downloaded the Crashplan Linux Software, extracted and ran the installer - very straightforward. Loaded the Crashplan software, created my crashplan online account and did a test backup to a local folder.

NAS Server

I installed the Crashplan application, and fired up the interface:


Not much to do there, really. Then I had a look at the forum notes here. 

In the notes, it suggests creating a Crashplan shared folder, which I did, and then restarting the Crashplan service:

[/share/CACHEDEV1_DATA/.qpkg/CrashPlan] # ./ restart
Stopping CrashPlan... 
Sleeping 10 seconds...
Cleaning /tmp/*.jna files...
Cleaning /share/CACHEDEV1_DATA/.qpkg/CrashPlan/tmp/ files...
Starting CrashPlan... 
Using interface: eth1 ( - This can be changed in the web interface!

Next, on a PC client (NOT the server itself) change the config file
to look at the server's IP address:

#Fri Dec 09 09:50:22 CST 2005

Run the Crashplan client again, and it should prompt to log in with your Crashplan online account. All being well, this now links the server with your account. Change any server setting you want, then close the Crashplan client. Re-edit the  file back to the local PC's IP address:
#Fri Dec 09 09:50:22 CST 2005

And run the Crashplan client again, this time you should be able to run a backup of that PC's files to the NAS, as it should now appear in destinations / computers.

Check the Crashplan share on the NAS, it should now be populated with data archives from the backup. Set up a scheduled backup as appropriate.
