Yea, that's the reason:
Here a simple test on my same account (localhost), but should work also on different host: ~/o is my source dir on my account (with one more file) host:tmp/a is the last backup (with missing 3-file) host:tmp/b is the new backup (without any file for now) After rsync ~/tmp/b should also have all the files linked from a which are also not modified on local ~/o/ and created new files from o to b which are new or modified: pierre@in94:~$ ls -li o tmp/a tmp/b o: insgesamt 8 257419 -rw-r--r-- 1 pierre pierre 4 Nov 14 10:53 1 257420 -rw-r--r-- 1 pierre pierre 6 Nov 14 10:53 2 tmp/a: insgesamt 8 257315 -rw-r--r-- 1 pierre pierre 4 Nov 14 10:53 1 257316 -rw-r--r-- 1 pierre pierre 6 Nov 14 10:53 2 tmp/b: insgesamt 0 pierre@in94:~$ echo bluppblupp >o/3 pierre@in94:~$ echo bluppblupp >>o/1 pierre@in94:~$ ls -li o tmp/a tmp/b o: insgesamt 12 257419 -rw-r--r-- 1 pierre pierre 15 Nov 14 16:34 1 257420 -rw-r--r-- 1 pierre pierre 6 Nov 14 10:53 2 257421 -rw-r--r-- 1 pierre pierre 11 Nov 14 16:31 3 tmp/a: insgesamt 8 257315 -rw-r--r-- 1 pierre pierre 4 Nov 14 10:53 1 257316 -rw-r--r-- 1 pierre pierre 6 Nov 14 10:53 2 tmp/b: insgesamt 0 pierre@in94:~$ rsync -av --link-dest=../a o/ localhost:tmp/b/ pierre@localhost's password: sending incremental file list ./ 1 3 sent 226 bytes received 64 bytes 30.53 bytes/sec total size is 32 speedup is 0.11 pierre@in94:~$ ls -li o tmp/a tmp/b o: insgesamt 12 257419 -rw-r--r-- 1 pierre pierre 15 Nov 14 16:34 1 257420 -rw-r--r-- 1 pierre pierre 6 Nov 14 10:53 2 257421 -rw-r--r-- 1 pierre pierre 11 Nov 14 16:31 3 tmp/a: insgesamt 8 257315 -rw-r--r-- 1 pierre pierre 4 Nov 14 10:53 1 257316 -rw-r--r-- 2 pierre pierre 6 Nov 14 10:53 2 tmp/b: insgesamt 12 257422 -rw-r--r-- 1 pierre pierre 15 Nov 14 16:34 1 257316 -rw-r--r-- 2 pierre pierre 6 Nov 14 10:53 2 257423 -rw-r--r-- 1 pierre pierre 11 Nov 14 16:31 3 Thanks for the explaination.
