alternative sw:
FastCopy: https://fastcopy.jp
(had the best transfer rates with this sw over + to an older USB3 1st gen adapter/extHDD)
FreeFileSync: https://freefilesync.org
very flexible (include/exclude dirs+files, mirror/sync to extHDD etc)
Personal Backup: https://personal-backup.rathlev-home.de/index-e.html
(using this since years for backing up of changed/new data from MyDocuments partition into a daily/weekly ZIP)
