load should NOT even be noticable on backups ...
( tapes are super slow devices compared to other stuff the cpu does
- but than again, how fast is the cpu/disk/ememory on that "backup server"
?? - sounds like a normal box if you're playing quake on it
i think its noticeable due to travan not running at full speed ??
did you buffer up data in the queue ??
find /etc -print | egrep -iv stuff-you-dont-want | buffer | \
tar zcvf /dev/tape -T -
buffering your data will speed up the tape writes
which backup prog ... pick your choice ( all free )
