I find 'Support for .* is not implemented yet' in
usr/share/rear/output/PXE/default/82_copy_to_net.sh
usr/share/rear/output/RAMDISK/Linux-i386/90_copy_ramdisk.sh
usr/share/rear/output/default/95_copy_result_files.sh
as
case "$scheme" in ... (*) BugError "Support for $scheme is not implemented yet.";;
This shows that the root cause is your incorrect URL
OUTPUT_URL=file:/var/lib/rear/output/ ... OUTPUT_URL=null
and the incorrect duplicate setting of OUTPUT_URL.
See the rear documentation and the general RFC
how a URL must look like, e.g.:
nfs://lucky/temp/backup cifs://lucky/temp usb:///dev/sdb1 tape:///dev/nst0 file:///path iso://backup/ sshfs://user@host/G/rear/ ftpfs://user:password@host/rear/ (the password part is optional)
I will fix the misleading error message.

With
https://github.com/rear/rear/pull/932
rear now errors out instead of a BugError
for not implemented URI schemes because
it is not a bug in rear when some functionality
is not yet implemented.
FYI:
BugError is usually meant for things like
some code that is known to do "something" reliably # success is mandatory to proceed (any failure is unexpected) if not "something" then BugError "Failed to do something"
Another example is in lib/_input-output-functions.sh
BugError "Forbidden use of trap with '$@'. Use AddExitTask instead."
which detects a real programming bug.

@RolfWeilen
FYI
how to test current rear GitHub master code:
# git clone https://github.com/rear/rear.git # cd rear # vi etc/rear/local.conf # usr/sbin/rear -d -D mkbackup
i.e. configure and run rear from within the directory
whereto the rear master code was cloned from GitHub.
