Remember that each version of every file you keep take something like 600
bytes in your database. You are effectively saying you have up to 1830
versions of every file (5 years times 366 days per year). Times say 5000
files per system, and 600 bytes per version, is about 5.2 gig of database
space per server.  Now how many servers are you backing up? (most of our
servers have over 10000 files on them that we back up.
