Ideally, Icinga/Nagios/any server would be on HA system but that,
unfortunately is not an option. But of course, Icinga can't monitor
system it's on, so I plan to monitor it from my own machine.

Like I said, it's several dedicated, mostly web servers with users
uploaded content on one of them (that part is expected to grow). None of
them is in the same data center.

I talked to my boss about it. Since this is backup server, downtime is
acceptable to him. Regarding risks of data loss, isn't that the reason
to implement RAID configuration? "R" stands for redundancy. If hard disk
fails, it will be replaced and RAID will be rebuild with no data loss.
If processor or something else fails, it will be replaced with expected
downtime of course.
