Comment 7 for bug 1562357

I find it absolutely crucial for the users to at least be informed about this. If they're not, my opinion is, this is a critical bug which renders this software partially malicious. (no joke).

If you're not informed that *some* arbitrary but unknown data (namely `.steam/...`, but user doesn't know this, because he's not told so, and which user is to say that `.steam` is the only thing or keeps being the only thing) is excluded from the backup, then this software doesn't provide ANY data safety for the user.

Multiple users reported being unpleasantly surprised and dismayed by a "Backup Software" they were using (and making an effort by providing a backup volume and computer time for it to run) not backupping data, they *explicitly* wanted being backed up.

In Short: This software is intended for people to use to have peace of mind about the safety of their data. This is no minor issue. It is a *trust* issue: We can't trust deja-dup to backup that which we do not want to lose. Therefore it doesn't provide peace of mind but does the exact opposite: Is my data safe? Idk! The devs arbitrarily decide if my data is important! And they can do so with every update of the software!
