RE: DASD performance curve graphs??

[PaulMmn <PaulMmn@xxxxxxxxxxxxx>]

At work our PCs are connected via a LAN.  Every user has access to a
private folder on a file server.  It is the user's responsibility to save
files to the LAN.  The LAN is backed up every night.  If it's not on the
LAN and you lose it, that's your own tough luck.

At home, *sigh*, I don't have access to a DLT tape drive.  Yet.  On my
Wintel machine I'm running NT/Server so I can use mirroring and RAID.  On
my Macintosh I'm still running without a net...

As someone (here?) mentioned, it would be better to duplicate my disk farm,
then clone the live to backup on a regular basis.  That way, I won't lose
everything if a file directory error clobbers a raid set.
