The issues you mention are all fixed in 3.x. In 2.x, BackupPC_nightly
wouldn't run until the last running backup finished. New backups were
deferred until after BackupPC_nightly finished. Therefore, a single
slow client would delay BackupPC_nightly and then all other backups
too, even if $Conf{MaxBackups} allowed more. In 3.x the backups run
independently of BackupPC_nightly, so they run concurrently.
This also means that restores can run at any time in 3.x, although they
are considered a user requested backup, so the $Conf{MaxUserBackups}
limit applies. It's unlikely you will run up against that limit, but
if so simply increase it.
