Been using this backup plugin for years - and it periodically just stops working. It'll go weeks or months without sending a backup to me via e-mail as configured - then suddenly it'll start working again. I use Lester Chan's WP-DBManager concurrently, and it has never failed to work. I like them both, except that Matzko's just dies. If anyone has any info on this, I'd appreciate knowing it. Thanks to both authors for providing these plugins.
