Crashplan upload performance

Hi everyone, this is my first post here, be gentle with the noob!

I got myself an Ultra 2 recently and everything's smooth. I'm using Crashplan for cloud backup and happy with that too. I even managed to get Crashplan installed on the ReadyNas and have set it up to do some backups. My backup nirvana dream world consists of me backing up my large collection of photos (about 300GB) to the ReadyNas and having the ReadyNas trickle it up to Crashplan in its own time.

This is working, except the upload speed I'm getting from the ReadyNas is about half of what I get when I use my laptop to run the backup, even though it's the same same file location for both - the ReadyNas. My DSL upload speed is about 1Mbps, which is not going to break any records. I get about 90-100KB/s uploading from the laptop, and only about 50KB/s from the ReadyNas. With that much storage, this means the initial backup will take a looong time.

I did a quick test by ftp'ing from the NAS to somewhere on the net and the upload speed was a lot faster than the rate I get running the Crashplan backups, so the ReadyNas is capable of uploading close to the limit of the line - just not when Crashplan is doing the uploading.

Does anyone have any suggestions for how to improve this? Thanks!

Re: Crashplan upload performance

could you offer any advice on how you got crash plan working? i have a pro 6 with 8gb of ram that i'd love to get it running on, but i'm not sure if it will work with the Java add-on that's out in the community area.

Hey Satiated,

Have you tried increasing the upload rate in CP's network settings?

Below is a good guide to help with increasing CP's speed.

I'm about 3 months in of my initial seed. So far I've up'd about 1.4TB. My ISP upload bandwidth is capped at 1.9 Mb per sec. and CP maxes it out. I normally throttle it at 1 Mbps so my normal browsing isn't effected.

I'm out of town for a couple days but when I get back I'll give it a go with the community Java add-on.

I don't know about the add-on. I'm a Linux and java noob. I followed the steps in this thread (after reading it from start to finish) for installing java and Crashplan on the NAS and it went smoothly. I then went and found the stuff on pointing a client on another machine to the crashplan server on the NAS (I think it was on Crashplan's site) and that went fine as well. HTH

Hi fbmachines,

Thanks for your reply. I followed the steps in that article - no improvement in speed. It's still sitting at around 450-500kbps. I did another ftp test to a ftp server on the net, sending a 5MB JPG and it got around 1040kbps. The line speed is 1300kbps, so 1040kbps is probably pretty close to the max it's capable of.

I ran "top" to see if it's maxing out the CPU - it's not. Crashplan is using about 10-15% CPU and it's the only active process on the machine.

I did notice that there's only 24MB of free physical memory on the box. The java process for crashplan is using 682MB of virtual memory and has 71MB of phyiscal memory, if I'm reading top's output correctly.

Confused!
