DO NOT REPLY [Bug 6996] New: syncing backups - autodetect older variants already existing on receiver
https://bugzilla.samba.org/show_bug.cgi?id=6996 Summary: syncing backups - autodetect older variants already existing on receiver Product: rsync Version: 3.1.0 Platform: Other OS/Version: Linux Status: NEW Severity: enhancement Priority: P3 Component: core AssignedTo: wayned at samba.org ReportedBy: bugzilla.samba.org at zmi.at QAContact: rsync-qa at samba.org We use virtualization, each server makes it's backup to a central backup server. That backup server rsyncs every day the diffs to another site. Many of the servers make a "backup.tar.bz2", and keep the older version as "backup.tar.bz2.old" or "backup_old.tar.bz2". These files tend to be large, so it would be nice not to sync them, just rename them on the receiver site. rsync currently transfers the "*old*" version despite it exists already on the receiver, it's just still named "backup.tar.bz2" and would need to be renamed to "backup_old.tar.bz2" (or backup.tar.bz2.old depending on how it is named now). It would be very interesting to have a feature to search - within the same dir for files with "similar" names and autodetect if they are the same - within the same dir for subdirs which have the same content and have just been renamed. This is for backups that do "backup/0", "backup/1", and so on, just renaming the dirs each day. That should result in just a rename on the receiver side. It could reduce the backup traffic a lot. Maybe name that options "--search-similar" I think nearly everybody uses "generations" of backups, just renaming them on the original server. So this would free the Internet of unneccessary traffic during the night. -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact.
