Transfer completed torrents only when both pc are turned on?

[sgrunt]

I use an Eeepc 900 for torrenting, because of its low power consumption and so it is 24/7 on.

My uTorrent automatically moves downloads, once completed, onto my main pc (they are on lan), and it works, obviously if both the pc are on.

The problem is that the main pc it's turned off when i am not at home. And so what happens if the download completes while the destination pc is turned off?

There is a way to move completed files only when the destination pc turns on, or retrying to send completed files until until the pc is available?

I presume that actually, if the "completed files" folder it is not available when the file is completed, i loose the file.

Tnx!
