The beta is scheduled for sometime within the first 15 days of April, the stable will take about a month to be released. The alpha tag is there to denote that not all features have been implemented yet. It's quite stable already, I use it to produce daily backups of this and other sites I manage.
Akeeba Backup uses a different backup engine, much improved when compared to JoomlaPack, especially in terms of performance. Furthermore, once the stable version of Akeeba Backup is out, JoomlaPack will stop being supported. In fact, no development effort is put on JoomlaPack any more. The reason to go with Akeeba Backup Professional right now is not just one thing, it's a collection of many factors:
- faster backup
- native command line / CRON backup mode
- ability to automatically upload your backup archives to Amazon S3 and DropBox
- Regular Expressions filters to automatically exclude unlimited number of files, directories and tables based on naming criteria
- Allows the use of database and folder filters on extra databases and off-site directories respectively
- New features are added all the time
For some people this may make the difference, for some it may be an insignificant improvement to their backup experience. It's up to you to decide.
