Description

If you backup a large file that is mostly holes, previously we'd issue
a seek for every block... For large (Exabyte sized files) this would
issue lots of unneeded seeks, so combine them...

Thanks for the work Jan, sorry took so long to commit... And an item
completed off the IdeasPage!
