RE: Puzzling System Action

["Alex Moore" <alexm@xxxxxxxxxxxxxxxx>]

Cache card which plugs into the IOP is designed to hold it's data via battery 
attached to card.  Therefore, controller can fail and
although you are down, you do not _NECESSARILY_ lose data.  However, if little 
tiny 3" x 3" cache card actually fails - bye bye data
(all of it - forever).  Ask me, I know.  Also, if doing SAVCHGOBJ for 
incremental saves between SAVLIBs, for files that are
journaled, _ONLY_ receivers are saved (unless specifically overridden).  This 
means recovery involves applying journal entries after
restoring library - mucho time expended.
