Installed CrashPlan on my ReadyNAS Ultra 4

I use CrashPlan+ (20% discount link, I do not get any bonus) to backup my computer (Mac) to the cloud in addition to using TimeMachine. I just installed CrashPlan on my ReadyNAS Ultra 4 for automatic backup 🙂 Here is how I did it (adapted from these instructions. You will have to buy an extra subscription for the NAS or upgrade your existing subscription to a Family subscription. Installing CrashPlan on the ReadyNAS itself rather than adding the NAS when mounted to your computer means that the NAS can backup itself. In my case this also means a faster backup since I use WiFi on my computer and the NAS is directly connected to my router.

Go to the CrashPlan-install directory and run ./

% cd CrashPlan-install
% ./

Below follows a dump of my interactions:

Do you accept and agree to be bound by the EULA? (yes/no) yes

What directory do you wish to link the CrashPlan executable to? [/usr/local/bin]

What directory do you wish to store backups in? [/usr/local/var/crashplan] /crashplan-backup
/crashplan-backup does not exist.  Create /crashplan-backup? (y/n) [y]

What directory contains your SYSV init scripts? [/etc/init.d]

What directory contains your runlevel init links? [/etc/rc2.d]

Your selections:
CrashPlan will install to: /usr/local/crashplan
And put links to binaries in: /usr/local/bin
And store datas in: /crashplan-backup
Your init.d dir is: /etc/init.d

  1. That worked great for me…. been wanting to back the NAS up directly and not via a mount to something else. Thanks!
