I recently had a hard drive failure while transitioning to an aufs/snapraid configuration using OMV on my Proxmox box. I ended up losing about 3TB of data, of which 800GB was not backed up on another device in my network. Ouch. Fortunately I had Crashplan Pro running for the past few years and backing up everything.
I first started using the Crashplan Restore option in my Windows 8 box but was constrained to having it run at between 6 – 10 mbps, which was estimated to take over a week to restore all of the data. I spoke with Crashplan support and they said this was normal as I was sharing the line and resources with other users. Fine, I thought, but I don’t want to keep my primary Windows computer on for days on end when I could just setup one of my VMs on my headless server to do the work. I had left it running for a few days already but only received about 200GB of data.
Surprisingly when I setup my OMV box to use Crashplan’s GUI by installing LXDE and the Crashplan application my download speeds skyrocketed to saturate my entire 50mbps line! I was surprised to see over 500GB downloaded in a single day through my OMV box. I thought I would share this for those who might be restoring a huge quantity of data but complain about slow speeds on their Windows box. I wasn’t able to resume the existing progress from my Windows box — so I ended up overwriting the 200GB that Crashplan had already downloaded in Window — but the speed more than made up for it.
I dedicated 3 CPUs and 8GB of RAM to my OMV box while it’s doing this and it’s eating up about 30-50% of my CPU while it does this. Not too shabby!
