I hope I'm not duplicating something someone has already said --
/tmp may not be the best possible choice for backups. A reboot
could potentially "help" by cleansing that directory. Off-host
copies (eg, scp website-20110101-1459.tgz fred at otherhost:/home/fred/backups/)
would address a number of risks.
