It’s happened to me twice now: CrashPlan stops backing up my files apparently due to a failed software update. I usually don’t know CrashPlan has stopped backing up until I get the weekly email status update. Fortunately, the files that I back up to CrashPlan are not changed often at all, and missing a backup for a couple days isn’t the end of the world.
I have CrashPlan installed on my QNAP (see my previous post about that), and CrashPlan smartly autoupdates their software every now and then. Unfortunately this autoupdate doesn’t seem to work when installed on QNAP. The following instructions should help get CrashPlan updated and running again smoothly.
Connect to the CrashPlan server running on QNAP by first creating an SSH tunnel to QNAP and then open the GUI client locally (connecting to the CrashPlan server through the ssh tunnel). The GUI reports that “CrashPlan Upgrade Failed. CrashPlan failed to apply an upgrade and will try again automatically in one hour…”
How to upgrade (I had version 3.2.1 installed, version 3.4.1 was available):
Stop the CrashPlan server:
$ /share/MD0_DATA/.qpkg/crashplan/cprun.sh stop
Move the existing CrashPlan installation out of the way:
$ mv /opt/crashplan /opt/crashplan.bak
Download the latest linux version of CrashPlan, decompress the tarball, etc
$ wget http://download.crashplan.com/installs/linux/install/CrashPlan/CrashPlan_3.4.1_Linux.tgz $ tar xzvf CrashPlan_3.4.1_Linux.tgz $ rm CrashPlan_3.4.1_Linux.tgz
Edit the CrashPlan install.sh, replace the bash path and add
BINSLOCat the top:
$ cd CrashPlan-install $ nano install.sh #!/opt/bin/bash BINSLOC="/bin /opt/bin /usr/bin /usr/local/bin"
Now, run the install script:
$ ./install.sh Would you like to switch users and install as root? (y/n) [y] n installing as current user No Java VM could be found in your path Would you like to download the JRE and dedicate it to CrashPlan? (y/n) [y] y jre will be downloaded ... Do you accept and agree to be bound by the EULA? (yes/no) yes What directory do you wish to install CrashPlan to? [/root/crashplan] /opt/crashplan /opt/crashplan does not exist. Create /opt/crashplan? (y/n) [y] y What directory do you wish to store backups in? [/opt/crashplan/manifest] /opt/crashplan/manifest does not exist. Create /opt/crashplan/manifest? (y/n) [y] Your selections: CrashPlan will install to: /opt/crashplan And store datas in: /opt/crashplan/manifest Is this correct? (y/n) [y] y ... ./install.sh: /opt/crashplan/bin/CrashPlanEngine: /bin/bash: bad interpreter: No such file or directory CrashPlan has been installed and the Service has been started automatically.
Oops, need to fix some paths in /opt/crashplan/bin/CrashPlanEngine. Add the
BINSLOCat the top of the file, and add the full path to
#!/opt/bin/bash BINSLOC="/bin /opt/bin /usr/bin /usr/local/bin" ... /opt/bin/nice -n 19 $JAVACOMMON $SRV_JAVA_OPTS -classpath $FULL_CP com.backup42.service.CPService > $TARGETDIR/log/engine_output.log 2> $TARGETDIR/log/engine_error.log &
Now, move the backed up configuration/cache folders into place:
$ mv /opt/crashplan.bak/conf /opt/crashplan/ $ mv /opt/crashplan.bak/cache /opt/crashplan/ $ mv /opt/crashplan.bak/manifest /opt/crashplan/
Then start CrashPlan:
$ /share/MD0_DATA/.qpkg/crashplan/cprun.sh start
Connect from the client and verify in the GUI that the server is now working:
And finally, clean up the unused, old crashplan backup (mine was 2.1GB as there seemed to be 100s of failed yet downloaded upgrade attempts):
$ rm -rf /opt/crashplan.bak
First up on my QNAP: offsite backup of my data in “the cloud”. QNAP’s recommended and integrated cloud backup provider was a bit too expensive for my taste, especially since I plan to backup nearly 1TB of data. After some serious googling I found the perfect candidate: CrashPlan.
CrashPlan’s software–written in Java–has two components, a server and a GUI client. This makes it a perfect candidate for QNAP. Get the server running in headless mode on my QNAP, then connect to it via the GUI client from my desktop machine.
- First up with the QNAP, install Optware IPKG.
- Then follow Cokeman’s excellent guide for CrashPlan on a QNAP.
- Installed CrashPlan for OSX and modded the
servicePort=4200as in CrashPlan’s docs (to edit I used TextMate):
$ mate /Applications/CrashPlan.app/Contents/Resources/Java/conf/ui.properties
- Added a tunnel to my QNAP in SSHKeyChain(an excellent program to manage SSH connections and tunnels):
- Open CrashPlan on Mac. Because of the
ui.propertiesconfiguration change, you will now be connecting from CrashPlan’s Mac GUI to the CrashPlan engine on QNAP. Go through the CrashPlan setup, configure backup options, done!
