Hello, I use rsync (3.0.9) to make backups with the link-dest option, so that I keep daily folders, and I only upload the difference.
However, when a directory is moved somewhere else in the tree, it is fully re-uploaded. Same thing when files are simply renamed, they are re-uploaded, not linked. First option could be to use --fuzzy twice (migrating to 3.1.0), but I think that it can be very IO intensive on receiver side, with 20 link-dest and hundreds of thousands of files in each link-dest. Second option could be to use the db.diff patch on receiver side. Several question then on this second option : - Does this patch have to be compiled on both sides, or only on receiver side ? - Can the db.diff patch work with link-dest option ? - How, like this ? If the file is not found in one of the link-dest (and only if), then, rsync will try to find it in the database, using its checksum ? - Is the checksum the table key, to speed-up the research ? Is there any third option ? I see many checksum / link-dest patches in rsync-patches-3.0.9.tar.gz, anything more efficient than db.diff ? Thank you very much for your help, Best regards, Ben
