Resilio Sync has disappeared from the FreeNAS Plugins Collection. Curiously, while Resilio Sync can still be compiled from a FreeBSD port, due to licensing restrictions, a pre-built binary package of the port is no longer available, so pkg install rslsync returns nothing from the FreeBSD package mirrors.
This scripted installation of Resilio Sync will create a jail, install the latest version of Resilio Sync (x64) for FreeBSD from resilio.com, and store its configuration and client backup data outside the jail.
