I have an EBS volume specifically dedicated to storing remote backups via rsync. This volume is attached and mounted to an EC2 instance. The user mediating backups has access to this volume via a symbolic link in the user's home directory. Everything seems to be functioning fine. The user writes to a folder and the writes all go to the attached volume, making it so that I only ever need to snapshot the backup volume.
However, here's the catch: When I monitor this volume in the EC2 Management Console no writes ever appear on this volume! In fact, all the writes are logged as going to the root volume.
My question is: Is this just a problem with AWS not properly accounting for disk writes that pass through a symbolic link across volumes? Or is there perhaps something wrong with my setup that I should be concerned about?
