Your're right, but this mounted network drive still has 500gb free space.
What could be is that device was not mounted correctly and that the backups are stored on the main hd. However my backupscript when it performs a Full Backup (on Monday at 2.02am) it consumes around 20gb and not 300gb.
And yesterday at 18.00 when the hd was full (0% left) it normally doesn't have a backupjob running.
