Failing on "not enough space" when plenty is available
I've had three backups fail to a remote share. In all three cases, the first error was from "backupmedium::reportioerror" claiming that there was not enough space to write to the virtual backup device.
However, there is plenty of space on the share. Well.. not plenty but enough. I was about 35GB into an 84GB backup file, with over 60GB remaining when I received the error.
The earlier errors had even more space available.
Is this something that the Red Gate virtual device is returning an error for? Is it guessing how much space will be needed based on compression ratios or something? Or did it just get a write error from the share?
