trouble with snapshots

[Marcin Ciesielski]

Dear all

I am struggling with the snapshot command 

I am using sdfs_3.5.8.3_amd64  on ubuntu 16.04

my volume is above 500GG set as a backup and low memory

for the test purpose all my dat sits in one folder DATA 

so my command is 

sdfscli --snapshot --file-path=DATA/ --snapshot-path=../.snapshots/DATA_SNAP

as I understand file-path is relative to the volume, the whole snapshot-path is relative to file-path

I assume that folder .snapshots will be created on the same level as DATA

I am completely lost

1. I don't see how to specify the volume in the command.

2. I am not sure if it is possible to take the snapshot of the whole volume and exclude folder .snapshots at is root

3. every time I run the command I get following exception, so I am not even sure if my command is correct
