This is getting off-topic, but FWIW my "new version" of rdiff-backup keeps a checksum of every single file it writes (including "meta" files that contain rdiff-backup specific repository information). This information is kept to allow fast, full repository verification. I also plan to have rdiff-backup verify each file during a restore operation so you will know that the restored data is exactly what was backed up. Well, at least to a very high degree of probability ... SHA1 hash collisions can happen, but then again ECC RAM is not perfect either. ~ Daniel _______________________________________________ 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
