We are running a file backup that is 2.64 TB, and it is failing. We were able to fix the image backup by changing the type from VHD to VHDx, but there is no way to make a similar change to file backups.
It needs to create a full file backup, and it keeps failing. We have more than enough space to do it, we just need the file backup to be able to back up all 2+TB.
