backuppc-rsync 3.1.3.0-3 (riscv64 binary) in ubuntu hirsute

 rsync-bpc (as it is called upstream) is a patched variant of rsync
 that has been developed specifically for server-side use with
 BackupPC (https://github.com/backuppc/backuppc) version 4. It extends
 the normal rsync so that it understands BackupPC 4's internal data
 structures on disk and can directly write to it.
 .
 You do neither need to use nor to install this package manually. It
 is pulled in as dependency where needed.
 .
 It is also no problem to install it in parallel with the normal rsync
 as it does not install any binary in the common search path ($PATH),
 just in a dedicated directory under /usr/libexec/.
 .
 In terms of functionality it replaces the less performant Perl module
 File::RsyncP (package libfile-rsyncp-perl) which was used by BackupPC
 version 3 on the server side.
