Oops. If fsck can't fix it, that's not good. Have you tried running fsck
by hand, i.e. without -p? If you run it from the console it can fix a
bit more than when running in preen mode, but this may result in data loss.

Make sure that the hardware isn't broken. If you have (S)ATA disks, use
'smartctl -a /dev/<yourdevice>'.
The canonical way to make backups is to use dump(8). Unmount /var and
use 'dump -0 -a -f <dumpfile>'.
But if the filesystem is really hosed, it might not be possible to copy
everything. In that case make a copy with dd of the partition that /var
is on so you can try to save any data that has not been backed up.
Probably the safest way to go is to newfs the filesystem that /var is on and
restore your latest backup.
