Dear Ubuntu SRU team, Would you please be so kind as to look into this bug and its proposed resolution? I have updated the bug description to match the SRU procedure to the best of my abilities. Thanks in advance, Lionel Sausin.
** Description changed: Binary package hint: rsnapshot - rsnapshot 1.3.0 (the version in lucid) has a known bug that prevents the - use of the link_dest and sync_first options simultaneously. The bug in - question is mentioned in the rsnapshot FAQ as the third question: - http://rsnapshot.org/faq.html + DESCRIPTION + rsnapshot 1.3.0 (the version in lucid) has a known bug that makes rsnapshot create a plain copy of the files instead of create hard links for all but the first backup point when using both the options link_dest (use rsnapshot's link-dest feature) and sync_first (seperate the rsync phase from the directory rotation logic). + This renders rsnapshot mostly useless in this configuration, since it will then consume huge portions of disk space instead of beeing rather frugal. + This bug is mentioned in the rsnapshot FAQ as the third question: http://rsnapshot.org/faq.html and was fixed in v1.3.1 (released with Maverick). - Upgrading rsnapshot to 1.3.2 or 1.3.2 will fix this bug. Can this happen - before lucid's release? + STEPS TO REPRODUCE + - Change the default config: link_dest[TAB]1 and sync_first[TAB]1, snapshot_root[TAB]/tmp/ + - run "sudo rsnapshot sync && sudo rsnapshot hourly ; sudo rsnapshot sync && sudo rsnapshot hourly" + - observe that the files in hourly.0 and hourly.1 are not hardlinks: the link count for is always 1 for /tmp/hourly.*/localhost/etc/hosts and the inode number is not the same: + + FIX + A minimal patch is provided as a bazaar branch. + + REGRESSION POTENTIAL + The fix short-circuits a failed attempt at smartly deciding whether --link-dest is usefull or not. The fix always call rsync with --link-dest. + This is not an issue for rsnapshot because --link-dest can only help rsync create more hard links - unless there is a bug in rsync itself. + So the risk is rather low. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/519031 Title: rsnapshot in Lucid does not support using link_dest and sync_first simultaneously -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
