No evidence with respect to your assertion exists in your post.
These two commands
backup filesperset 20 format 'ARC%S_%R.%T' (archivelog like 'T:\ARCHIVE\ARC%');
delete noprompt archivelog all backed up 1 times to sbt_tape ;are potentially contradictory, but as you also don't provide the log_archive_format parameter who can tell.
