Any idea how to troubleshoot this? My backup volume is on a ZFS pool and I’m getting lots of hardlink errors in the urbackup.log on the server.
No one?
Maybe the files are on different ZFS volumes?
You could run UrBackup in strace to get the “link” return code or add log output to os_create_hardlink in os_functions_lin.cpp . I’d also try to manually hard link the files UrBackup tries to link. Maybe “ln” has a better error message.
