Yes. It would. Magic isn't real. To truly know that a source and destination are identical, the entire source must be read. As must the entire destination. Period. If the two are on seperate computers joined by a network, you can do this two ways: 1) Transfer the contents of one of them entirely, over the network. 2) Run a process on each to reduce blocks of each file to checksums, and transfer just those checksums. ISCSI and NFS are not capable of letting the remote machine run processes on the server. SSH is. Rsync will run the comparison on both machines. _______________________________________________ rdiff-backup-users mailing list at [email protected] http://lists.nongnu.org/mailman/listinfo/rdiff-backup-users Wiki URL: http://rdiff-backup.solutionsfirst.com.au/index.php/RdiffBackupWiki
