Can Time Machine backups become corrupted when backing up to a NAS? Short question : When backing up you mac to via Time machine to a 3rd party NAS (non time capsule, but instead something like a Synology or Drobo NAS). Can the time machine backups become corrupted and unusable, either due to the laptop / computer being turned off, disconnected from the network or for some other reason. 

Long question : Im evaluating using Time Machine vs Carbon Copy Cloner as a backup solution. When speaking to Carbon Copy Cloner they mentioned that backing up to a NAS as opposed to a direct HDD wasnt the best idea as the backup could become corrupted, im going to ask them why this might be, but i also wanted some impartial input, any ideas why this might be and would Time Machine suffer the same issues ?
Time Machine really wants an HFS- formatted volume. Try creating a sparse disk image on the NAS and backing up to the image.
