Backup software comparison

[scuba at centroin.com.br]

Hi all,

	I´ve used AMANDA for my backup solution for a long time, and now I
decided to look for an alternative with multi-volume, disk-to-disk,
network copy, among other features.
	Does anyone had compared other open source backup software?

	I´ve seem something about: Bacula, BoxBackup

	Which are the most used backup solution arround here?

Thank you,
