I'm running rsync to sync a directory onto my external USB HDD. It's about 150 gigs of data. 50000+ files I would guess.
It's running it's first sync at the moment, but its copying files at a rate of only 1-5 MB/s. That seems incredibly slow for a USB 2.0 enclosure. There are no other transfers happening on the drive either.
Here are the options I used:
rsync -avz --progress /mysourcefolder /mytargetfolder
I'm running Ubuntu Server 9.10.
