Hi all, OpenBSD 4.3-current (GENERIC) #0: Wed Mar 19 04:21:24 CET 2008
As anyone else, I use dump(8) for my backups. Now I experience this: I made a full dump a while ago with dump -0 -a -u -f /backup/dump.var.www /var/www Since then, /var/www got much smaller (you wouldn't believe the amount of bullshit people put online). If I do the same dump now, the resulting dumpfile (/backup/dump.var.www) is as big as before - it never gets smaller, eventhough I am dumping a much smaller filesystem now. Why is that? Of course, this won't happen when if I run e.g. dump -0 -a -u -f - /var/www > /backup/dump.var.www because then the dumpfile gets truncated right away. But the dump happens inside daily.local, hence I want the > redirection for logging: dump -0 -a -u -f /backup/dump.var.www /var/www > $LOG 2>&1 What I did is rm -f /backup/dump.var.www and than run the dump again. Now the dumpfile IS accordingly smaller. Can someone enlighten me? Perhaps 'dump -f' does not truncate the file? Thanks Jan
