UPDATED: See filzip77's post below for a guide\Tutorial on how to installI’m new to the forums so please be gentle ….I’m looking to venture into having a dedicated/off the shelf NAS rather then the DIY version I have been running for a while. The ReadyNAS Duo\NV+ v2 (ARM version) definitely sticks out as the top runner.The one thing that is stopping me taking the plunge is I’m unclear on if it can cope with running Crashplan.I understand that Crashplan is java based and that the older “sparc” Duo cannot run it. But is there a way to get Crashplan running on a newer Duo v2? I’ve searched then forums but it’s a little unclear. I have seen comments around the web stating folk have done it but not with any detail that gives me any confidence so splash my cash.Any help on this matter would be much appricated.

No. Look at the system requirements: http://www.crashplan.com/consumer/download.html?os=LinuxYou need at least 1GB RAM. The ARM products have 256MB RAM that is not upgradeable.You'll need to get an x86 ReadyNAS (e.g. Ultra, Pro) if you want to run Crashplan. There are instructions on the forum on how to install it.Welcome to the forum!

Thanks for the quick response.Thats the one thing I never checked...doh! Would have saved myself a ton of time. Ah well.Looks like the Ultra might be longer term investment anyway. I'm laughing through because the DIY system I'm looking to replace would have the same spec as the Ultra plus.

I have NV+ which is afaik ARM and it's upgrade-able to 1GB. Although those RAMs are quite a bit expensive, so I didn't do that..

Gucek, what version of RAIDiator?The Sparc NV+ (v1) which runs RAIDiator 4.1.8 and has the Frontview web-interface (looks like http://www.readynas.com/simulators/frontview/) is very different to the new ARM NV+ v2 which runs RAIDiator 5.3.x and has the new Dashboard web-interface.The NV+ v2 was released on Nov 13th 2011, so if you purchased before this time you'd have the v1.I've posted an article on telling the difference between the v1 and v2 here: How to tell whether I have a Duo v1 or Duo v2 or NV+ v1 or NV+ v2

Hello,I have just acquired a new Readynas duo v2.In one of the previous message of this thread, mdgm replied it was not possible to install crashplan on the Duov2No. Look at the system requirements: http://www.crashplan.com/consumer/download.html?os=LinuxYou need at least 1GB RAM. The ARM products have 256MB RAM that is not upgradeable.I also read on internet there is a guide howto install crashplan on Synology NAS (with the same processeur ARM and the same amount of memory).Here is the link: http://pcloadletter.co.uk/2012/01/30/crashplan-syno-package/If it runs on a Synology ARM based, it must also runs on the readynas duo v2.No problem for the download/installation of the the sun-java runtime 7. I tried but the tuto doesn't explain how to get the library "libmd5.so" for arm.Did someone already do it for our NAS?Philippe

Was wondering if you guys were seeing any speed issues?
Normally I get 1.2Meg up but at the moment it does not seem to go over 300k up....have tried a few setting on the Crashplan client but to no avail...

Are you CPU bound?

Not sure what you tried, but the normal adjustments are

advanced backup settings

You can also try
network settings

sending message buffer size=2560though I didn't find it made much difference on the Pro. It did no harm though.

I've also found that performance varies by file type.

BTW, if you want to restart the service after you apply changes, try clicking on the house icon on the upper right of the client. It will open a command box, with a reference list of supported commands. Restart is one of them. Stopping the service (which is also there) is not so useful, since the client can't restart it.

I kept all default values.
The default upload transfer increased and stabilized around 1.3 Mbps (most of the files are pictures of 5MB).
I decided to limit the upload to 800 Kbps in order to do not slow down too much my internet connection.

Have you check your CPU load? The command is
top

What are the size of the files you transfer? Remember that the NAS ARM has a CPU much less powerful than in your PC. Computing the hash table (MD5) for a big file may use a lot of CPU time on the ReadyNas ARM.

On my side I did not notice a high CPU load during the transfer.

This depends on the file size and the file extension. Photos are probably small enough that CPU load is not a factor. DVD or BluRay media files are another matter. Though at 1 mbps it might not be practical to back those up to CrashPlan Central anyway.

The 3.2 engine seems to be better on CPU than the older 3.0 engine though. My pro is uploading at about 8 mbps at the moment, and the CPU load is only 3%. I think it was much higher in early March (with the old engine). Back then I was frequently saturating one of the Pro cores. It is still taking about half the memory though.

I may have been following a red heron. I was checking through my my.service.xml file looking to change some settings and noticed that my servicehost setting had not been set correctly (0.0.0.0). when I fixed it crashplan started to sync correctly older files rather then upload them.
once the initial sync is done I will take a closer look at the upload speeds I get.
one thing I have noticed is that crashplan does start to slow on PC when you have a vast amount of small files....I'm guessing ths part MD5, part file reading, part de-dup & part compression. I will tale a closer look once the intial sync is complete.

Thanks for the feedback though. will give me plenty to fiddle with.

Has anyone noticed crashplan not auto-starting on boot?

The init script is correctly linked in /etc/rc2.d, and calling it manually starts crashplan proving the script/link are valid. But it doesn't appear to work on boot. I haven't checked more deeply to see if the script is just not called or if crashplan fails for some reason, and I have a cron job that regularly checks crashplan is running as a precaution that works around the issue anyway.

But anyone else seen this?

Also - has anyone figured if this setup survives a firmware upgrade?

It starts up automatically when I reboot my pro, and survived the firmware update from 4.2.19 to 4.2.20
