Package: rsync Version: 3.0.9-3 Severity: important Hello,
I've accidentally noticed that my home directory backups (done using rsync and --link-dest set to last backup directory) are taking up much more space than expected. Investigation revealed that the unchanged files are actually not hard-linked, as I would expect. Here's a small demo: jurij@paddy:~/tmp$ mkdir src jurij@paddy:~/tmp$ touch src/foo jurij@paddy:~/tmp$ rsync -r /home/jurij/tmp/src/ link jurij@paddy:~/tmp$ ls -al link total 8 drwxr-xr-x 2 jurij jurij 4096 Aug 4 10:13 . drwxr-xr-x 4 jurij jurij 4096 Aug 4 10:13 .. -rw-r--r-- 1 jurij jurij 0 Aug 4 10:13 foo jurij@paddy:~/tmp$ rsync -r --link-dest /home/jurij/tmp/link /home/jurij/tmp/src/ dst jurij@paddy:~/tmp$ ls -al dst total 8 drwxr-xr-x 2 jurij jurij 4096 Aug 4 10:13 . drwxr-xr-x 5 jurij jurij 4096 Aug 4 10:13 .. -rw-r--r-- 1 jurij jurij 0 Aug 4 10:13 foo jurij@paddy:~/tmp$ stat dst/foo File: `dst/foo' Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 807h/2055d Inode: 1572876 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ jurij) Gid: ( 1000/ jurij) Access: 2012-08-04 10:13:46.007097660 +0100 Modify: 2012-08-04 10:13:46.007097660 +0100 Change: 2012-08-04 10:13:46.007097660 +0100 Birth: - jurij@paddy:~/tmp$ As you can see, the file dst/foo has link count of 1, and I would expect it to be 2, as it should be just hardlinked to link/foo. In case it matters, /home is its own partition, with ext4 filesystem. Corresponding line from mount output (all options are default, as set during install): /dev/sda7 on /home type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered) I'm pretty sure that it used to work before, I've been doing the backups the same way for a couple of years, and older backups do have files hard-linked, as expected. If this bug is confirmed, I would expect its severity to be bumped to RC.
