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.
You can rerun the
ducommand with--count-linksto count hardlinks multiple times. If that shows >780GiB you have a lot of hardlinks somewhere, which you can narrow down by rerunning the command on each of the subdirectories in your home directory.Your options would be to delete the hardlinks to decrease your total file size, exclude them from the rsync with
--exclude, or repartition your SSD to a filesystem that supports hardlinks.With --count-links, it is just 384G so that is probably not the issue?
