[Freedombox-discuss] FBX Snapshots Module on Rasberry Pi 3

[julian]

Hello all.

Similar but maybe outdated question? 
https://github.com/freedombox/Plinth/issues/568


Quick question:

Is it possible to use Snapshots on freedombox running on a raspberry pi 
3?

I am trying to install Snapshots but I get this crazy error:

Error installing application: ('snapshot', '', 'Creating config failed 
(/sbin/chsnap not installed).\nTraceback (most recent call last):\n File 
"/usr/share/plinth/actions/snapshot", line 161, in <module>\n main()\n 
File "/usr/share/plinth/actions/snapshot", line 157, in main\n 
subcommand_method(arguments)\n File 
"/usr/share/plinth/actions/snapshot", line 61, in subcommand_setup\n 
subprocess.run(command, check=True)\n File 
"/usr/lib/python3.5/subprocess.py", line 398, in run\n output=stdout, 
stderr=stderr)\nsubprocess.CalledProcessError: Command \'[\'snapper\', 
\'create-config\', \'/\']\' returned non-zero exit status 1\n')


According to the Issue #568 
(https://github.com/freedombox/Plinth/issues/568
) SunilMohanAdapa says that this error is because raspberry pi is using 
ext4 and NOT btrfs.

So my question is: can btrfs be used on a raspberry pi running 
freedombox?

I essentially want to have to snapshots and backups of my fbx. And I 
know this could be achieved many ways (make a cronjob with rsync, etc) 
but I would like to try out the Snapshots module that is built into 
freedombox.


I tried to ask on IRC and it was a ghosttown....

thanks so much,
J.J.
