Fixing CrashPlan after Synology DSM 4.0 upgrade

After upgrading my Synology DS710+ to DSM 4.0 (which had its own set of problems) I found that I needed to do a little work to get CrashPlan working again. For this I went back to Kenneth Larsens blog.

At least one user had reported upgrading to DSM 4.0 and had a short summary of what they did to get it working again but I didn't really use his steps. Instead I decided to just try reinstalling over the top of my current folders.

I had a few problems because most of the programs didn't want to install if I had existing folders with the same names. I deleted the /usr/lib/ipkg folder and then I ended up renaming my current /opt/ folder (/volume1/@optware/) to /volume1/@optware.old  so that I could keep everything intact in case I needed it. Here's the command:

rm -rf /usr/lib/ipkg
mv /volume1/@optware /volume1/@optware.old

I was able to follow Kenneth's instructions down through step 7 though I still had my old install folder so I was able to skip steps 1, 4, 5, and 6 and instead just moved my folder back to the /opt/ folder to do the installation:

cp -r /volume1/@optware.old/CrashPlan-install /volume1/@optware/

At that point, rather than modify all of the files again, I simply deleted the /opt/crashplan/ folder and copied my old copy of the folder to where it was as follows:

rm -rf /volume1/@optware/crashplan
cp -r /volume1/@optware.old/crashplan /volume1/@optware/

I still had to do step 10 Kenneth's blog but after that I was able to start the crashplan engine and connect to it from my desktop client.
