From the looks of your syslog messages, it appears that you are running 6.x. The good news here is that when the time expires under 6.x, the disk scrub picks up at that point on the next disk scrub. So you may not be scrubbing every sector every week, but you will be scrubbing every sector every 2 or 3 weeks.
Does this sort of restarting from a checkpoint (presumably the information in the state.raid.scrub.* entries in /etc/registry) apply if the scrub was interrupted by a "raid scrub stop" command?

normally the disk scrub starts on sunday 1 a.m. cause of the running ndmp-backup, the filer couldn't finish the scrub within the default deadline time of 6 h.
and it seems to me that a sensible thing to do would be to interrupt the scrub if it hasn't finished by the time the backups start, rather than let them madly compete with each other for disk bandwidth.
