There is a long standing bug that AFAIK it was never fixed, that it corrupts the backups if you close/disconnect the laptop while it's doing a backup it will leave the disk in a corrupted state.
It's not the NAS fault usually.
I've switched to an external HD always plugged on my "docking station" as Time Machine backup for this reason. Although it's annoying to remember to unmount the HD (and check if a Time Machine backup is in progress) before disconnecting the laptop :/
