Not sure there's too much we can do here... there's too many levels of symlinks. ;( You could change your host to not have so many, or --exclude-symbolic-links to avoid them in the backup. What kind of filesystem is your backup going to?
This is a very long standing problem. My backup runs 2 cycles: 1- first backup everything 2- then remove everyting that is older than a certain date This problem _always_ occurs in cycle 2, never in cycle 1. Which is weird to me, I'd expect it to fail already in cycle 1 if there really were too many levels of links.
See also bug #1044065
Ah yes. I recall that bug now... I tried to gather info there, but didn't have any luck tracking it down. I'd suggest you ask upstream, but sadly upstream is pretty dead these days. ;(
Yeah I need to switch to a different backup solution, but am lacking the time a bit. Will probably go for BackupPC
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
