Are these Syslog entires ok for a working Timemachine backup

I´m still trying to get Timemachine working which is the case with two of my Macs but not with a third one.

I was looking into the log and here are the entries. Here is an error:

Nov 17 11:14:30 Tower afpd[5143]: uam_load(uams_dhx2.so): failed to load: libgcrypt.so.11: cannot open shared object file: No such file or directory

...and here is just one example of ton´s of entires in amber:

...but I think this is more of interest:
