I want to backup an existing SSD on a new notebook with a pre-installed Windows, Recovery Partition, ... before I wipe it and install Ubuntu on it. (It is too small for a dual-boot)
Until now I have been using
dd for that kind of situation. But now I have read on various sites that
dd isn't a good choice for SSDs. These are the things I came across:
ddalso fills empty areas with 0s reducing spare area. This makes sense to me
ddmay mess with alignment. I tried reading up on alignment but I still didn't get it entirely. If I do a bitwise copy of a SSD and later put it back on the same drive shouldn't this make them totally identical including any alignment?
- dd puts unnecessary wear on a SSD. I understand that it would be better to only write areas with actual data, but is this really such an issue on a modern SSD?
My questions now are:
- Do the things stated above make sense? (This is just for personal interest, my main questions follow)
ddtherefore a safe choice for backup/restore of a whole SSD drive?
- If not, is Clonezilla better suited?
- Otherwise: What is the best way to go?
