yes, but that's on the side of the backed up host, meaning it would only
work to ensure no two "hosts" pointing to the same machine via
ClientNameAlias were backed up simultaneously, wouldn't it?
One more remark concerning MaxBackups though. As I read the code,
MaxBackups = 1 does *not* mean "only one backup per wakeup", does it? Are you
sure simultaneous backups are speeding things up? It undoubtedly would if
you were using distinct slow network links, but for many people the limiting
factor seems to be BackupPC server disk seeks.
