When running
rsync -Paz /home/sbird "/run/media/sbird/My Passport/sbird"
As told by someone, I run into a ran out of storage error midway. Why is this? My disk usage is about 385 GiB for my home folder, and there is at least 800 GiB of space in the external SSD (which already has stuff like photos and documents). Does rsync make doubly copies of it or something? That would be kind of silly. Or is it some other issue?
Note that the SSD is from a reputable brand (Western Digital) so it is unlikely that it is reporting a fake amount of storage.
rsync does not delete files at the target by default, it has kept all of the original files when they were deleted from the original source location.
You must specify --delete for it to also delete files at the target location when they are deleted at the source.
The directory “sbird” in the SSD did not exist beforehand though?
Are you saying this is your first run?
Run ‘ncdu /run/media/sbird’ to find out why there’s no space on it.
