time of automatic activation and deactivation (syntax is “him”). When snapshot start is set, the
snapshot will be deactivated and activated again at the given time.
Alternatively, snapshots can be taken manually in the Maintenance->Snapshot menu even if
snapshots are automatically created under “Snapshot Definition”. Button remove all can by
useful for removing all snapshot at one time.
Snapshots are shared via SMB/CIFS protocol, but for authenticated users only. Access to
snapshots can be granted in Maintenance->Snapshot.
Recommendation: Use only as many active snapshots as really needed – a large count of
active snapshots can slow down the system considerably.

Note: The snapshot will become inactive if the content exceeds the snapshot
capacity. Also, please take into account that changing the amount of snapshots will
automatically reset the whole snapshot configuration!
Configuration example:
Snapshot Res.% Begin End
Snapshot02 50% 6:45 N.A.
Snapshot03 5% 10:00 10:30
Snapshot04 10% 13:00 13:40
Snapshot05 10% 15:00 16:00
Snapshot06 1% 16:00 22:00
This example is suitable for companies that start working at 7 am and end around 3 pm.
Every morning - before everybody starts working - snapshot02 will by created (refreshed). This
snapshot is designed to hold data from the beginning of working day untouched to the end of
the day. This will enable simple access to files changed at the same day in order to look at
previous file version.
After three hours of work, the second snapshot (03) will by created and will stay active for 30
minutes. At this time, the backup server (Brightstor, for example) will connect to clients that
are running Rorke GalaxyLX NAS and backup all data. This same situation repeats at 1 pm
and 3 pm - but with one difference - at this time, there is much greater activity (many more
files are written), because at 3 pm all changes are stored in expectance of leaving off work.
The last snapshot with only 1% reserved space is forerunning backups on a tape device with a
backup server. This backup takes much more time as backing up one single hard drive.
