i use backwpup on multiple sites, and just upgraded to 3.0.3 today on 2 sites. i can't get the backup to finish now on either site. it runs "forever" during the zip archive stage and never completes. i don't use 3rd party sites for backup, just backup to my site (including xml and all files).

Maybe these are the aborted zip archives?
it's a great plugin, but please fix asap. Thanks!
let me know if you need any info. (send me an email address). i'll be happy to help.
