> Samba's fruit_get_num_bands() failed, but the "purgeable" in the bundle name indicates that this is a backup deemed broken by Apple's Time Machine (see e.g. https://www.baligu.com/pondini/TM/C13.html).  So it seems Time Machine won't do anything with it and I shouldn't expect Samba to repair it for me either.
