Comment 4 for bug 1543491

As usual there are to solutions: fast to implement and more optimal from storage space handling point of view.
The first, a fastest solution would be just using big enough partition for the whole /var (not /var/log - not sure what practical outcome this decision brings)
The second, more optimal solution, would be to compress snapshot data on nodes and then "tar" on the master node when necessary on the fly during downloading it via Fuel UI. This would free a lot of space required to store uncompressed data.
