Rsync only hard-links a file with its --list-dest version if it is not transferred. Using --ignore-times causes all files to be transferred, so a --link-dest hierarchy only supplies file data for a more efficient transfer (assuming the transfer is remote) when combined with -I. > If --ignore-times is not specified, only mtime and the file size is > checked so rsync doesn't notice that other inode information changed > (ctime and links). You want the --checksum option. If you want rsync to hard-link together files with differing attributes (such as differing mtime), that attribute must not be specified as preserved (e.g. --no-times) OR you could have rsync copy into a hierarchy of files instead of an empty hierarchy as an alternate means of treating the history of file attributes as unimportant. One way to speed up the --checksum option is a preliminary patch named check checksum-updating.diff in the patches dir. It's purpose is to maintain .rsyncsum files in the source based on extra file data, such as ctime and (coming soon) inode. When this is done right, it will allow a new kind of transfer check that is not as expensive full-file checksumming and not as fragile as only monitoring size and mtime. ..wayne.. -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
