How calculate the size of the data downloaded and the space
occupied in the FTP server?
The quantity
of the data downloaded per day
from the station depends
mainly on the storing rate and, marginally, on the number of downloads.
Even the number of the events (alarms, etc.) slightly effects the size of the
data downloaded.
Supposing just a daily download and using EHA-2B-01 antenna the quantity
of the data downloaded is the following:
Rate 1 min 720 kB
Rate 2 min 360 kB
Rate 6 min 120 kB
Rate 15 min 48 kB
In this case, the space occupied on the hard disk does not differ a lot from
the amount of the data downloaded.
Differently, if the station was set for accessing to the server each hour (24
downloads per day), because of the minimum memory occupied by every
single file (hard disk clusters dimension used), the space daily occupied on
the server FTP disk, with cluster of 4kB, could be even the double of the
actual data.
