until someone accidentally deletes an important backup from the other one ;)

btw, made backups yesterday.

tar -c -b 128 /home | mbuffer -m 400M -p 95 -s 65536 -D
32G -A "mtx -f /dev/sg2 next" -f -o /dev/st0

my tapelib has a 35/70gb dlt built in. After 10(!) mb mtx signaled to switch
tapes.

After one hour of hunting (updating mbuffer, re-emerging mtx and playing
around with different options) I made an ls -lhtr of /dev to see if all nodes
are there. There weren't. And st0 had a size of 10M. WTF? mknod'ed the node -
didn't help. On turning on the lib, udev made three nodes. sg2, the 10mb st0
and tape/by-id/blabla. Reloading the modules created a lot more nodes - and
solved the problems.

Sometimes life is a lot easier with less automation.
