I have a Windows 10 computer running Veeam Endpoint Free. It is set to backup nightly to another Windows 10 computer over an Ethernet network. It has been working fabulously well until last night. It has started returning an error stating that the network path was not found (to the backup target, presumably). The server is present on the network, I can log into it remotely from the computer I am attempting to backup. I have another Windows 10 machine that also backs up to the same physical drive, albeit a different directory; that backup functioned normally. The main differences between the computer that backed up normally and the one that failed are the one that worked is only about 152 GB (the entire backup directory), whereas the one that failed is 1.23 Tb (the entire directory). Also, the computer that had the backup fail has three physical drives, of which two are bitlockered. The computer that did backup has one physical drive that is open. Lastly, after this happened, I created a new directory on the same target drive as the directory that could not be found, and started a backup. It is cranking along without complaint. I am left wondering if there is a size limit to the backup target directory.
