Backups sometimes need a non-64KiB transfer cluster size.
See patch #2 for the detailed justificaton.
===
v2
===
01: Removed "sectors_per_cluster" as a cached property of the Backup Block Job,
In favor of recomputing it with a small function where needed.
(I like v1 more. Thoughts?)
02: Expand correction to all backup modes instead of just incremental.
Added credit: Thanks to Fam Z for noticing this problem!
03: Minor phrasing change in a comment.
Added r-b.
