Re: FAILURE AND STRANGE DUMP SUMMARY

Is there any proper mysql backup that can backup database without stopping
it??
If so, I don't have to worry about it? Of course it wasn't failed but I just
worried if I recover it and the database or tables might be corrupt just
because Amanda detected strange. Please advice.
