Not true, at least by default... rsync assumes that if the files'
names, timestamps, and sizes are the same, then it can skip computing
the checksum. You can override this behavior with the "--ignore-times"
or "--checksum" option, but you probably don't want to.
Hard drive is EXT4 and LUKS; flash drive is FAT32
I bet this is your problem. FAT32 timestamps have a resolution of 2
seconds. ext4 has a resolution of nanoseconds. So the timestamps
essentially never compare equal and rsync is always reading the files
to compute their checksums.
Try giving the "--size-only" option to rsync.

Hi Pat,
Thank you!
Just out of curiously, what would happen if I switched
to NTFS? (Can't use EXT4 on Windows machines.)
