I'm using bareos to back up a bunch of PC workstations.
First question: do you have the .conf file set to reuse or not?
My first guess is, if the d/b was corrupted, or it couldn't append to the
incremental, or full, then it would decide the whole thing was new, and
"incremental" would be a full b/u.
mark, who's just finished working with his manager on a decent nightly
b/u report for bareos
