Crashplan Linux Headless Wont backup

I just installed crashplan on a new linux headless server and it refused to backup, I checked logs and found it was having issues with the noexec flag on my /tmp/ folder. so I created a new tmp folder and told it where to access it. In this article I give simple instructions on how to fix Crashplan Linux Headless backup errors.

The main folder for Crashplan Linux Headless install for me is :

/usr/local/crashplan

so I created tmp folder within it and made it 777 (probably unsafe somehow)

mkdir /usr/local/crashplan/tmp
chmod 777 /usr/local/crashplan/tmp

edit /usr/local/crashplan/bin/run.conf and in the first line from

SRV_JAVA_OPTS=”-Dfile.encoding=UTF-8 -Dapp=CrashPlanService -DappBaseName=CrashPlan -Xms20m -Xmx512m -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0″

change to

SRV_JAVA_OPTS=”-Djava.io.tmpdir=/usr/local/crashplan/tmp -Dfile.encoding=UTF-8 -Dapp=CrashPlanService -DappBaseName=CrashPlan -Xms20m -Xmx512m -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0″

so basically just add -Djava.io.tmpdir=/usr/local/crashplan/tmp

another thing is 512MB is very low amount of max ram for a large server with lots of backed up files so I changed that also. I changed the part in red from 512 to 2048 (which is 2 GB). Crashplan suggests 1GB ram per 1TB of backup. this is ofcourse a rough number and I have not followed it in my usage for Crashplan Linux Headless installs but its a good number to keep in mind where possible.

SRV_JAVA_OPTS=”-Dfile.encoding=UTF-8 -Dapp=CrashPlanService -DappBaseName=CrashPlan -Xms20m -Xmx2048m -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0″

with both above tweaks it will look like this :

SRV_JAVA_OPTS=”-Djava.io.tmpdir=/usr/local/crashplan/tmp -Dfile.encoding=UTF-8 -Dapp=CrashPlanService -DappBaseName=CrashPlan -Xms20m -Xmx2048m -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0″
