The r-services were used a lot on and between Unices.
FTP did fail a lot indeed. That is why scene (FTP / FXP) used .rar, .sfv and Usenet .rar, .par(2). Download clients had resuming support but did not attempt verification. That's why checking checksum is important (Sfv is just CRC32 and Par is Reed Solomon, other examples are MD5 and SHA1).
Later on scene used so-called auto traders, which utilized FXP and automatically verifying checksums plus anticipating on errors (such as dupes). The I know was called Preee (Windows only, worked in Wine). Later protocols like BitTorrent implemented checksum verification within the protocol.
