https://bugzilla.samba.org/show_bug.cgi?id=8456 --- Comment #7 from Wayne Davison way...@samba.org 2013-12-25 23:25:53 UTC --- The latest rsync will now look into link-dest dirs even for files that exist in the destination directory hierarchy. It still requires all preserved attributes to match for the link to occur, though (e.g. if preserving --times, the mtime must match). What it doesn't yet support is an option to tell rsync to not modify attributes on any hard-linked file in the dest hierarchy (they still get their attrs tweaked in-place). -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the QA contact for the bug. -- Please use reply-all for most replies to avoid omitting the mailing list.

Re: [Bug 8456] improve --link-dest bahaviour
In general - --link-dest works as expected *only*, if the destination directory is empty. Going along with this idea of ensuring the destination directory is empty. LBackup is a rsync backup wrapper system which may be of assistance in this regard. --- This email is protected by LBackup http://www.lbackup.org -- Please use reply-all for most replies to avoid omitting the mailing list.

Re: [Bug 8456] improve --link-dest bahaviour
I'd like to use rsync as an efficient (== do not store the same file twice at the backup media) backup solution. The backup should be made into N remote directories (rotating each day) _without_ the need to delete the remote directory before. This is essentially, what LBackup is doing. However, keep in mind that if the transfer is interrupted. The incomplete backup will be deleted and then it will be restarted only using the latest successful backup (with regards link-dest). LBackup will always backup to a clean (empty) backup destination directory called Section.inprogress. The LBackup project is open source. As such, you are free to have a look at the code to get an idea of what it is doing or even fork the project (github - makes this easy) for your specific requirements. Also, keep in mind that if a file is not hard linked to save space and it has been updated then it will end up taking up additional space on the destination backup system. I have not experimented with de-duplicating file systems. However, if you want to save on space then this may be an avenue to investigate as well with regards backups, regardless of wheather you use LBackup, a different wrapper, rsync directly or some other system. I hope this helps. --- This email is protected by LBackup http://www.lbackup.org -- Please use reply-all for most replies to avoid omitting the mailing list.

Check out PCBackup -- it can use rsync (either via ssh or a daemon) and stores files without duplicates. There's also a diff in the patches called link-by-hash that will hard link files together that have the same hash because it maintains a directory of hash-named files. ..wayne.. -- Please use reply-all for most replies to avoid omitting the mailing list.

https://bugzilla.samba.org/show_bug.cgi?id=8456 --- Comment #3 from Kevin Korb rs...@sanitarium.net 2011-09-14 15:44:28 UTC --- The simple fact is that two links to the same inode are not 2 different files but the same file. Their attributes by definition are the same. They cannot have different time stamps. If you tell rsync to synchronize time stamps then it will update the time stamp in the target. It cannot do that and maintain the time stamp in the link-dest (which is read only as far as rsync is concerned) at the same time. This is simply impossible. Note that if you do not synchronize timestamps the result would be pretty much the same as --ignore-times which would probably be a bigger problem for you. The only thing rsync could possibly do would be to add an option to allow for minor changes to affect the files within the link-dest (and probably other previously used link-dests). -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the QA contact for the bug. -- Please use reply-all for most replies to avoid omitting the mailing list.

That behavior is documented in the man page: This option works best when copying into an empty destination hierarchy, as rsync treats existing files as definitive (so it never looks in the link-dest dirs when a destination file already exists), and as malleable (so it might change the attributes of a destination file, which affects all the hard-linked versions). -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the QA contact for the bug. -- Please use reply-all for most replies to avoid omitting the mailing list.
