i have a client who is wondering about backup options for their

What is their threat model? What are they trying to protect against?
Theft? Fire? Flood? Earthquake (you're only about 300 miles from the New
Madrid surprise)? Ordinary equipment failure? Drunks driving through the
front door? Frozen yaks falling from the sky? Assuming the facility is
physically secure, perhaps installing a few extra hard drives on each
server, and doing a nightly rsync (A1 to B2 and C3, B1 to C2 and D3, C1
to D2 and E3, D1 to E2 and A3, and E1 to A2 and B3) would do the job. Five
systems - maybe a nightly full backup of one server to a tape along with
incrementals from the other four servers - with the tape going off-site
ASAP? Really, a lot depends on how much data there is that needs to be
backed up, how often the data changes, and how long the data has to
be kept. Maybe a combination of the two techniques would be better.
what would be a good, cost-effective, easy-to-admin backup solution?
they don't need any enterprise-level stuff (no veritas)... (are the
legato products for linux expensive like veritas netbackup?)
Both Amanda and Bacula are pretty good - some people think that Amanda
is a bit of a handful to set up, but once it's running it's pretty
easy.
are there any good open-source solutions? (is there anything other
than tar, cpio, dump, etc.. that i'm missing?) or at least LOW-cost?
Depends on what your exact needs are. There is no one perfect solution
for everyone.
