NOTICE: The path to consider in the scripts below depend on your CrashPlan version

CrashPlan Home users: /var/packages/CrashPlan/target

CrashPlan PRO users: /var/packages/CrashPlanPRO/target

(Probably) CrashPlan SMB users: /var/packages/CrashPlanSMB/target


Based on the comment from Per at, here’s a suggestion for locking access to the upgrade folder (making it read-only) and hence blocking the auto-upgrade process altogether. This will stop any future update occurring automatically.

Disable the Upgrade:

Note that you shouldn’t let this run too long without actually upgrading, as it may result in loss of connectivity to CrashPlan’s servers if they decide that older versions are obsolete:

cd /var/packages/CrashPlan/target
sudo mv upgrade upgrade.tmp
sudo touch upgrade
sudo chmod 444 upgrade


When there is a new update available the CrashPlan log should show a recurrent upgrade trials and the GUI will show this notice:

Re-enable the Upgrade / Reset:

To reset it to its default state, just retrace your steps:

cd /var/packages/CrashPlan/target
sudo chmod 755 upgrade
  (755 should do it)

sudo rm upgrade
sudo mv upgrade.tmp upgrade

    As of 3/7/2018 this no longer works and they are somehow still managing to write to this folder (even chmod 000 does not work) and the app still manages to update completely breaking a headless Linux install. I’ve been trying to find a work around for the past two days in order to keep Crashplan 4.9 running and now the expense of moving my business to another RELIABLE business backup solution is looking better by the hour. Massive negative to Code42 here.
