What are Snapshots ?
Snapshots are system state images that store configuration data, application data and personal files and folders of your live system.
They are similar to persistent images as they store changes you make to your live system persistently in one file (called live-sn.squashfs)
In contrast to a persistent image those snapshots only get updated when you shutdown your live system and if you want it.
Snapshots are saved as squashfs compressed image files in ZevenOS-Neptune by default. Those Images can be used to create or share user specific systems with others. So it kind of enables the user to create a partial remaster and share the settings which he changed with other users.

How to create a snapshot ?
ZevenOS-Neptune provides the snapshot script which allows you to create a snapshot (live-sn) file on your live usb stick. Just execute snapshot from a terminal or run menu

How to use snapshot files ?
Make sure you rename them to live-sn and put them on your live usb stick. You then only need to add persistent at the end of the boot loader parameters that you can get by pressing TAB in the live usb bootloader.

How to use the snapshot file without rewritting it on every shutdown ? (without persistency)
This is also possible. The only thing you need to do is copying the live-sn* file to your ZevenOS-Neptune Live Sticks /live directory and create the filesystem.module textfile which should look like this:
This method doesn't require to add persistent at the end of the boot loader parameters.
Notice: the star (*) symbolizes a file name which can be either live-sn.squashfs or live-sn-xmas-kde.squashfs or live-sn-foobar.squashfs

How to share snapshot files ?
To share please see How to create a snapshot and make sure not to create fancy hardware tuning settings for your specific hardware like for example installing the nvidia or fglrx (ati) driver. Then simply just upload those snapshot files somewhere and create a thread in this subforum with the name and short describition (perhaps also a screenshot) of your snapshot.

Is there a Demo video ?
Yes we have a demo video explaining the snapshot method and giving a explanation on how to use existing snapshots.
