Backup failed too many levels of symbolic links

Today I want to check the backup file But I found the date not right than I check the backup log [QUOTE] Cpanel::Exception::IO::StatError/(XID sd9emd) The system failed to obtain filesystem information about "/bkup/nfs//.meta" because of an error: Too many levels of symbolic links at /usr/local/cpanel/Cpanel/Exception/CORE.pm line 336.
