I find that legatos lack of reporting tools is disappointing. Getting any stats 
from legato is a VERY manual process.

When we were looking at backup products in 1999, we narrowed the
list to TSM (then known as ADSM), Legato and Veritas.  Aside from
the differing backup methodologies (TSM - incremental forever) vs
Legato and Vertitas (full, incremental and differential) and the difference
on cost, it usually just a toss up.  No matter which one you pick,
there will be something that you end up not liking about it
(it may be the user interface or the amount of resources it consumes when
doing backups/restores or interfacing with the vendor on getting fixes,
new releases, licensing issues.

Basically you have to define up front what 'your' criteria is (cost,
ease of use, breadth of usable clients, etc, etc).
