Hi, I am backing up about 500G of data from a linux-based NAS to a USB hard drive attached to a router (rt-n16 with tomatousb firmware). Both NAS and the router have rsync-3.0.9. The router is running rsync in the daemon mode. To test the set up, I rsync'd the files to the empty USB hard drive, then back to the NAS in a new temp dir. Afterwards, I did a local "diff -r" on the NAS. To my surprise, a few files were corrupted (only 3 out of 17K files). "cmp -l" shows single byte difference between the original and rsync'd files. However, I didn't see any error message on the NAS side or in the rsyncd logs. How is that possible? Doesn't rsync always do a checksum verification after copying the files? I have been using rsync for years for local backup. The feeling of silent file corruption is scary. Could someone point me to the right direction? I really want to get to the bottom of this. Much appreciated.
