I'm using Sprite Backup version 6.1.0, Build 2192, on my xv6800 and scheduled backups work just fine for me. Earlier versions of Sprite Version 6 were unstable and shamefully buggy upon release, but this build finally seems to be what we needed. Sprite's products usually are the best, but I'll never buy another "n.0" release from them again... I'll wait until the .1 or later.
