@Lorenzo Jabber On listbox, You can choose *.imgc (compressed) or *,img (not compressed). Compression of encrypted data is pointless because You will not gain almost anything and significantly making longer the process.
It have sense only in not encrypted sectors, and with in majority of not compressed data: on sector level but also on file abstraction level (i.e images like JPG, PNG, WEBP, all films, music like MP3, FLAC; are already compressed and another one will not shrink them much).
You did sector by sector copy - but compressed. Which means that, decompression will take similar amount of time like compression took. So in this case, better is just delete it and make another backup, this time not compressed (which in addition as a bonus: can be used by any software which offering writing image back to media (DMDE, HDDRCT, IsoBuster, dd, ddrescue etc.)).
