I just finished backing up my production linode disk image to my other linode. They are both in the same data center (Atlanta) and the backup of 2048 MB took 10-11 minutes. I tried to not shut down the running production server before clicking the "clone button" just to see if it would work anyway. It seems to have worked. Me and 2-3 other users are the only users of it, so I guess it worked due to very low disk usage on my production server. Anyway.. I edited a mediawiki page on one of the servers and clicked refresh on both. The update only registered on one of the servers which is how it should be. I haven't done any more testing but it seems that this cloning feature you have implemented works just as I expected. I noticed that the Dashboard job only got visible on the receiving linode account and not on the sending linode account. That is no biggie but would be nice if you fixed.

I really appreciate you implementing this. It makes testing changes to a production server so much easier without the need to shut it down for long periods of time. Are we still being "charged" for the bandwidth this process would use? If yes; can you make it possible to run two linodes on the same physical server so that any backups of this kind would be from localhost to localhost and thereby not generate any traffic on the network? That way you could choose not to charge for the bandwidth generated by a backup process. Wow. What a useful feature. I really appreciate you implementing this.
