My cable modem was down for about 1 1/2 days, so I'm going
thru over 500 message..
Not clear on the no easy way of verifying message. With my g4l
project I've found that compressed images of disks or partitions
can easily be checked using the compression tools built in testing
tools. After creating images, I run the lzop -t image.lzo and if it
comes back with OK, then I've never had a problem. I once had a
corrupted image file, but it failed the test, and turned out to be a
bad ram stick in the machine, and once replaced it has worked
fine for years.
Having an untested backup of any type is not a good ideal. Many
users never check there backups just assuming that will work. I
generally wipe a disk in front of the students to show them how
quickly it can be restore if one has a good backup versus having
to rebuild a machine from scratch plus all the data that may no
longer exist anywhere..
