Assuming no snapshots. Do full backups (ie. tar or cpio) eliminate the need for a scrub?
No. A scrub verifies correctness of all the metadata and file data. A backup will only read (and verify) only as much as is required for the backup. Besides failing to verify redundant copies, the backup will fail to verify data which is retained by snapshots. The backup will also fail to verify disk data which is already cached in RAM.
Regardless, a successful backup goes a long way toward providing assurance that the filesystem is working correctly.
