+ The network protocol of versions 1 and 2 of <systemitem
+ role="package">rdiff-backup</systemitem> are incompatible. This
+ means that you must be running the same version (either 1 or 2)
+ of <systemitem role="package">rdiff-backup</systemitem> locally
+ and remotely. Since buster ships version 1.2.8 and bullseye
+ ships version 2.0.5, upgrading only the local system or only the
+ remote system from buster to bullseye will break <systemitem
+ role="package">rdiff-backup</systemitem> runs between the two.
+ </para>
+ <para>
+ For conveniency, version 2.0.5 of <systemitem
+ role="package">rdiff-backup</systemitem> is available in the
+ buster-backports distribution, see <ulink
+ url="https://backports.debian.org/";>backports</ulink>. This
+ enables users to first upgrade only the <systemitem
+ role="package">rdiff-backup</systemitem> package on their buster
+ systems, and then independently upgrade systems to bullseye at
+ their convenience.
