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.

    These differences really are insane. Maybe someone more knowledgeable can comment on why different tools differ so wildly in the total size they report.

    I have never used BTRFS, so I must resort to forwarding googled results like this one.

    Could you try compsize ~? If the Perc column is much lower than 100% or the Disk Usage column is much lower than the Uncompressed column, then you have some BTRFS-specific file-size reduction on your hands, which your external exFAT naturally can’t replicate.

      percentage of total is 83% (292G vs uncompressed 349G apparently)
