In current GitHub master code we have in
usr/share/rear/prep/NETFS/default/060_mount_NETFS_path.sh
which is a symlink to
../../../backup/NETFS/default/100_mount_NETFS_path.sh

mount_url $BACKUP_URL $BUILD_DIR/outputfs $BACKUP_OPTIONS

while in
usr/share/rear/output/default/100_mount_output_path.sh
we have

mount_url $OUTPUT_URL $BUILD_DIR/outputfs $OUTPUT_OPTIONS

i.e. BACKUP_OPTIONS vs. OUTPUT_OPTIONS.

I remember from another issue that
when OUTPUT_URL is set then the right OUTPUT_OPTIONS must be set too
but when only BACKUP_URL is set then OUTPUT_URL and OUTPUT_OPTIONS
inherit their values from BACKUP_URL and BACKUP_OPTIONS,
via the code in usr/share/rear/prep/default/020_translate_url.sh
cf.
https://github.com/rear/rear/issues/2398#issuecomment-630169870

@exfarmer
accordingly either specify

OUTPUT_URL=nfs://ussydd6300/data/col1/sylmar_linux_bu_image
OUTPUT_OPTIONS="nfsvers=3,nolock"
...
BACKUP_URL=nfs://ussydd6300/data/col1/sylmar_linux_bu_image
BACKUP_OPTIONS="nfsvers=3,nolock"

or - because both are same - only specify

BACKUP_URL=nfs://ussydd6300/data/col1/sylmar_linux_bu_image
BACKUP_OPTIONS="nfsvers=3,nolock"

The issue is missing documentation which should now be fixed via
https://github.com/rear/rear/commit/87d36f304ca4301bc1cfce55084b83260839695a

Hi,

I must of missed this in the documentation, I have removed the OUTPUT_URL from the local configuration file and now only specify BACKUP_URL and BACKUP_OPTIONS.
This worked.

You can close the case.
Thank you
