Picture Server Storing Millions of jpg's!

[Shawn]

Hi guys,

I have a system of IP camera's that are supposed to FTP snapshots upon
motion sensing at a number of remote sites.  The cameras seem to send
far more pictures even when things are static and I've ended up with
litterally millions of 10-20K jpg's, not all of which I need to save as
it were.

I am having a great deal of difficulty managing theses pictures.  The
machines can  seem to handle the shear numbers.  The hardware is an
olde Quad XENON 500 with 4G's of RAM and a 300G 6 drive RAID 5 array.
EXT3 and XFS didn't seem to help.  Any suggestions for FS or
application(s) that may be helpful in this sort of situation?
