Graham,
This is a problem with shell (likely ssh) escaping of arguments that
contain a space.
For incremental backups a timestamp is passed as an argument to tar running
on the client. The argument should be a date and time, eg:
--after-date 2020-04-22\ 21:18:10'
Notice there needs to be a backslash before the space, so it is part of a
single argument, not two separate arguments.
You can tell BackupPC to escape an argument (to protect it from passing via
ssh) by adding a "+" to the end of the argument name, eg:
$Conf{TarIncrArgs} = '--newer=$incrDate+ $fileList+';
