The simple answer is:

Exception '[Errno 13] Permission denied: '/data/bl1/bl1''

Which means the rob.aster account at that IP address does not have 
proper permissions on the target server.

Secondly, you probably don't want to restore to the directory 
"/rdiff-backup-data" as that is the same as what rdiff-backup users to 
track its metadata.

...

You can use the --verify or --verify-at options to validate an 
rdiff-backup target directory (i.e. a location that has a 
"rdiff-backup-data" directory inside it).

In this particular example:

VALIDATELASTN is supposed to be a number (0+) which tells the script how 
many increments need to be verified.

RDIFFINCREMENTS ends up as a space-delimited list of the last N 
increments in the destination directory.

OFFHOST is everything before the double-colon, OFFBASE is the parent 
directory (ending in a slash) and DIR is the directory.  This might 
evaluate out as:

backups.example.com::/backups/myrdiffbackup

Notice the use of "--list-increments", which is also a way to test that 
you have specified your target server/directory correctly.

--------------------------------------------

if [[ ! $VALIDATELASTN =~ ^[0-9]+$ ]]; then VALIDATELASTN=5; fi
RDIFFINCREMENTS=$(
    rdiff-backup --list-increments ${OFFHOST}::${OFFBASE}${DIR} | \
    grep -o 'increments\..*\.dir' | \
    sed 's/^increments\.//g' | sed 's/\.dir$//g' | \
    sort | tail -n $VALIDATELASTN
    )

RDIFFINCREMENTS+=' now'
echo "rdiff-backup verify last $VALIDATELASTN increments"

for INCREMENTTIME in ${RDIFFINCREMENTS}; do
    echo "Verify backup at: ${INCREMENTTIME}"
    rdiff-backup --verify-at "${INCREMENTTIME}" 
${OFFHOST}::${OFFBASE}${DIR}

    status=$?
    if [ $status -ne 0 ]; then
        echo "" >> $TMPFILE
        echo "rdiff-backup verify failed with status: $status"

        echo "rdiff-backup --verify-at "${INCREMENTTIME}" 
${OFFHOST}::${OFFBASE}${DIR} failed with status: $status" >> $TMPFILE

        let ERRCNT+=1
        continue
    fi
done
