@kamil .fogsettings file is hidden. In linux when a file name begins with dot ( . ) then file is hidden.
Question on bitlocker. Yes and no will this be a problem. No it will not be a problem in that FOG will backup the protected images in RAW disk mode.
Yes it will be a problem because fog will not be able to resize the disk because the partitions are protected with bitlocker. Also if you move the image to a different computer, that bitlocker protected disk will not boot because the values stored in the TPM chip will be different on a different computer.
So while you can copy a bitlocker protected disk you can not move the image to a second computer and think that it will work.
