CrashPlan PRO Docker Container

Oct 25, 2017

I used CrashPlan years ago but eventually gave up on it because it needed to be always running in the background. I did like the functionality and how it worked since I actually needed to restore some files one time. I canceled my subscription back then and never really found anything better that was multiplatform.

I always wanted to get it working in a FreeNAS jail since that would be the ideal solution. I could never get the jail to work correctly due to some Java problems. FreeNAS Corral added virtual machine and docker capabilities and there was a CrashPlan container available. This made things easy so I signed back up and everything worked great.

Unfortunately, Corral was scrapped and is a dead project. So basically if I want CrashPlan backups to work, I’m in the same situation as before.

I can either stick with Corral until docker support is added to a supported FreeNAS release or I can move it to a Debian Linux server with the data mounted through NFS or sshfs. Corral has several bugs so I decided to move the container over to a Linux server so that I can eventually upgrade to FreeNAS 11. The servers are connected through 10 Gbit so the speeds are very good with compression turned off.

1. docker pull jlesage/crashplan-pro

2. /etc/systemd/system/crashplan.service

   • ``` [Unit] Description=CrashPlan PRO After=docker.service Requires=docker.service

[Service] Restart=always ExecStartPre=/usr/bin/docker pull jlesage/crashplan-pro ExecStart=/usr/bin/docker run –rm –name crashplan-pro -e CRASHPLAN_SRV_MAX_MEM=8192m -v :/config:rw -v :/data:ro -p 5800:5800 jlesage/crashplan-pro ExecStop=/usr/bin/docker stop crashplan-pro

[Install] WantedBy=local.target

   - Configure the memory, config path, and data path above.

1. `systemctl enable crashplan.service`

1. `systemctl start crashplan.service`

Connect to the UI using a web browser: `<ip>:5800`

You may need to increase the `inotify` limit. You can set that in `/etc/sysctl.conf`:

fs.inotify.max_user_watches=1048576 ```

Update It’s actually very easy to run a Linux VM under FreeNAS and use docker inside that. I ended up doing it a year+ later.
