Backup
NetFlow Tracker can back up its configuration, and optionally its long-term and real-
time databases, to a nominated folder on demand or on a schedule. The contents of
the folder are erased before the backup, so ensure that you move scheduled backups
to long-term storage if required. It may be advisable to schedule a backup to different
locations on alternate days.
Backing up the real-time database takes a long time and it is advisable to omit it on a
busy system unless it is essential.
To restore a backup you must first install exactly the same version as you had
previously – you may need to contact support@flukenetworks.com
to obtain this. Then,
open a command prompt and issue the following commands on Windows, replacing
paths as appropriate; <enter> means to press the enter or carriage return key:
c: <enter>
cd \nftracker <enter>
runany c:\nftracker c:\progra~1\java\j2re14~1.2_0
com.crannogsoftware.ulysses.CRestore –sourcefolder c:\nftbackup
<enter>
On Unix, issue the following commands in a terminal, again replacing paths as
appropriate:
cd /usr/local/nftracker <enter>
./runany com.crannogsoftware.ulysses.CRestore –sourcefolder
/var/nftbackup <enter>
Archiving
NetFlow Tracker can be configured to archive real-time data older than the age
configured in Database Settings
to a nominated location rather than delete it. Archiving
is enabled for a device in Device Settings
; the archiving settings page allows you to set
the archive location and mount archived data back into the system for reporting using
the Filter Editor
.
You can choose to have all archives stored in the archive folder, or you can choose to
store in sub folders for each device and/or day, Please note that NetFlow Tracker
does not delete archive files so you must ensure that they are moved from the archive
directory to permanent storage.
To mount an archive, enter the directory containing it in the box under “Mount
Archives” and press “List”; you can then select archives and press “Mount”. When
there are archives mounted they appear under “Currently Mounted Archives” and can
be unmounted by selecting and pressing “Unmount”. Note that mounting and
unmounting archives does not affect the archive file itself.
Mounting an archive from a device that was deleted or was never present on the
server is not supported.
