Josee Sevigny wrote to ask about disaster recovery. Assuming the
context is safeguarding your data, I'd add the following general
comments:

1. Make backup copies. Sure, we all know about this, but it's easy to
mess this up on a network. Some users store all data on the network
drives, some on their local hard disk, and some on a combination of
both. Make sure you know where your valuable data lies, and back up
_all of it_. Backup all your system software (thus, your various
config files) and your application software (thus, your preference
files and any document templates). Disasters often take out your
original software disks, and replacing them isn't a pleasant process.

2. Take the backups off-site. Most people who do their backups
religiously promptly store them in the desk beneath their PC. If the
PC goes to join Dorothy in Oz (Frank Baum's version, not the one with
the southern cross on its flag!), the desk will go to... and even if
it does land on the Wicked Witch of the East, do you really want to go
fetch the backups from her sister? ("Sorry ma'am, but do you mind if I
grab the backups?") Backups for my home PC are at work, and vice
versa. Backups at my former employer went home each night with the MIS
director. Current corporate backups are stored on-site in a fireproof
safe (good but not great), but I'm working on them...

3. Do a dry run. The best plans in the world are useless if they
contain a glitch or two you hadn't foreseen.
