=====Primary Data Server=====
I need a server to hold my primary (raw) data, that has not been subjected to processing or any other manipulation. I need this because i don't know what tool i will use in the future. At the moment i might use Splunk and Graylog2. But if i decide to use other tooling, it might be difficult to export the data. When the primary data is still available i can import that in the new tooling.

Starting points:
  * As less processing as possible. Store data as text files.
  * Syslog capable.
  * FTP capable.
  * scp/sftp capable.
  * rsync capable.
  * Redundant storage.
  * Archiving / compression?
  * Montoring / expected file age.
  * Back-up.
  * Silent bit rot detection

====Hardware====
  * ECC Memory

====Configure storage====
Incoming data will be stored locally on RAID10 redundant storage. It will then be synced over to a NFS share on a NAS for archiving and back-up. This way if the NAS suddenly isn't available, we will retry the rsync. If the NAS is available again the rsync will continue where it left off.

====Configure backup====
Configure a backup job on the NAS to remote storage.
====Install the server====
CentOS 6.5
====Install receivers====
===Syslog===
rsyslogd
===FTP===
vsftp
===scp/sftp capable===
ssh/sftp
===rsync capable===
rsync
====Monitoring====
  * Services: sshd, vsftp, rsync, rsyslogd
  * Filesystems
  * File age, specific logging
  * Bit rot detection, local and NAS share.
