The package sync won't delete anything, as has been discussed here on
May 6, when someone complained that a mirror didn't use delay-updates.
[note: Matt then mentioned repodata, I just wanted to be sure there
isn't anything else]

Because of the disk hit. Fedora updates very often involve more than
10,000 files, and all these renames in sequence hit the disk hard. A
few days ago an update of about 12,700 files took about 20min of
renaming, and another a few days earlier of >20,000 took more than
33min. During these periods the number of transactions in the disks was
around 98% of the maximum. Distributing the renames during the much
longer download time avoids these peaks.
