In addition to backups on tape, I like to backup my ZFS to removable hard disk. (Created a ZFS filesystem on removable disk, and "zfs send | zfs receive" onto the removable disk). But since a single hard disk is so prone to failure, I like to scrub my external disk regularly, just to verify the drive has not begun failing.

ZFS That Is When would it be necessary to scrub a ZFS filesystem? We have many "rpool", "datapool", and a NAS 7130, would you consider to schedule monthly scrubs at off-peak hours or is it really necessary? Thanks
