BTW, 2 x rsync incrementals of the same level will transfer more data
than one full + one incremental. So for example, doing 6 incrementals
followed by a full backup can in fact transfer a lot more data than
doing 7 full backups.

eg, if a file changes after the full backup, then each incremental
backup will re-transfer those changes. While a full will transfer the
changes but the following full/incremental will not re-transfer those
changes.
