The internal database is in a custom binary format, well suited to
storing this kind of data, and smart about things like subnet masks. It
uses flat files under the /home/inmon/data directory. The details are
not published.
If you wanted to load data into an external database, then you could do
that using a script (e.g. perl, wget) to extract data in ASCII format
and then load it into whatever tables you wanted to store there.

The configuration file allows you to specify:
KeepActiveMinutes = <minutes>
(data per interface by minute...Monitor->Traffic and Query->Interface
Traffic)
KeepHistoryDays = <days>
(consolidated hourly history...Query->Site Traffic, Query->Site Service
and Query->Interface Counters)
KeepFreeMBytes = <MBytes>
If the disk fills up, the oldest history data will be deleted
automatically until KeepFreeMBytes are free.
For details, see the help page on the configuration file.

If you wanted to back the data up, you can back up the contents of
/home/inmon/data/historyData. Be careful not to use a backup utility
that locks the filesystem, though. The Traffic Server does not behave
well under those conditions.

Happens automatically, see above.

If you have more questions, please ask.
