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.. > -- > Michael hennebry@xxxxxxxxxxxxxxxxxxxxx > "On Monday, I'm gonna have to tell my kindergarten class, > whom I teach not to run with scissors, > that my fiance ran me through with a broadsword." -- Lily > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have > a question?
