With "doveadm backup" you have gotten into such a state that the INBOX needs to be deleted and recreated to preserve it exactly as it's in source. But you're using Maildir format, which doesn't allow deleting INBOX. So possibilities:
a) Don't use Maildir format
b) Delete the entire Maildir manually with rm -rf and the next doveadm backup should work (if not then something strange is going on)per "b)", i explicitly 'rm' the Maildir
rm -rf /data/vmail/example.com/testuser/Maildir

hints/suggestions as to what?
for anyone interested, the causal issue is NOT directly the one reported in the non-verbose output
Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.rather, the relevant 'hint' is the
Debug: brain M: Mailbox INBOX: ... GUIDs conflict - will be merged latermessage seen only in the debug output.
In addition to
rm -rf /data/vmail/example.com/testuser/Maildirclearing the index data, configured here in a separate tree,
rm -rf /var/vmail-index/example.com/testuser/*does the trick.
backup, now, appears to complete.
