(Symantec nee Veritas) NetBackup and (EMC nee Legato) Networker are different products that compete in the enterprise backup space. Under the covers NetBackup uses gnu tar to gather file data for the backup stream. At one point (maybe still the case), one of the claimed features of netbackup is that if a tape is written without multiplexing, you can use gnu tar to extract data. This seems to be most useful when you need to recover master and/or media servers and to be able to extract your data after you no longer use netbackup. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
