I need help choosing a backup solution for a server amongst all the tools that I read about recently (rsnapshot,amanda,clonezilla,rsync,dd,duplicity,ba cula...).
 one disk (a RAID actually) with the live system (ubuntu server 10.0.4) running on it.
 another disk mounted to /media/backup on that same system
-be able to create compressed backups of  to  while  is running.
-be able to recover individual files/directories from 's backups to  while  is running.
-ideally be able to look at the files on  before restoring them to .
-be able to restore completely  from one of 's backups.
Any input is welcome
