Backups are going to an external 2TB SATA drive that is 47% full and running great. In addition to this, I have only one partial backup per day now, not even a partial every hour (using Smart Recycle right now). Shouldn't it keep 24 hourly versions no matter what, then daily for the last month and then weekly after that? I'm copying on an external HD (USB)It also seems that once you got a "partial" backup, all the files that are missing in this backup -- but are present in previous ones -- will get a full copy again.

In my case, this means that I have right now two or three copies of a few 100G ... It would also be helpful if the log message was more informative ...

Estoy restaurando la mquina en el servidor de backup (nfs) para testeat esto, y que todo lo dems se ha copiado corrctamente (entiendo que s).
