Hi, we backup eight Windows clients in an AD domain using BackupPC and tb-rsync-vss. This has worked flawlessly so far. The only problems occurred, when the clients did not wake up via Wake-on-LAN and were therefore unavailable. In this case, restarting the affected clients helped. Yesterday, I was completely taken aback, when I realised that the backups appeared to be running smoothly but were empty.
I then took a look at the XferLog files. Before the error, the XferLog files looked like this.

The link is no longer displayed in Explorer or on the command line. When I switch to c:\ on the command line, enter r, and complete the command with TAB, r.exe is displayed. So the link still seems to exist. Nevertheless, it is not displayed in DIR or Explorer. Running install.cmd again in openssh creates the link, but it is not displayed in DIR or Explorer. Do you have any idea what the problem could be?
