Tar backup error

Question

I followed this question: How to backup filesystem with tar using a bash script?

But when I run the script it gives following error:

: not found/backup.sh: 2: /etc/init.d/backup.sh: 
: not found/backup.sh: 5: /etc/init.d/backup.sh: 
: not found/backup.sh: 7: /etc/init.d/backup.sh: 
: not found/backup.sh: 10: /etc/init.d/backup.sh: 
: not found/backup.sh: 12: /etc/init.d/backup.sh: 
/etc/init.d/backup.sh: 13: /etc/init.d/backup.sh: Syntax error: "(" unexpected

Here's my script:

#!/bin/bash

#TODAY=$(date +%F)
#HOST=$(hostname)

mybackupname="backup-fullsys-$(date +%Y-%m-%d).tar.gz"

# Record start time by epoch second
start=$(date '+%s')

# List of excludes in a bash array, for easier reading.

excludes=(--exclude=/FILES/Media/Programs/Mint/Backup/$mybackupname)
excludes+=(--exclude=/proc)
excludes+=(--exclude=/lost+found)
excludes+=(--exclude=/sys)
excludes+=(--exclude=/mnt)
excludes+=(--exclude=/MEDIA)
excludes+=(--exclude=/BACKUP)
excludes+=(--exclude=/FILES)

if ! tar -czf "$mybackupname" "${excludes[@]}" /; then
  status="tar failed"
elif ! mv "$mybackupname" FILES/Media/Programs/Mint/Backup/ ; then
  status="mv failed"
else
  status="success: size=$(stat -c%s backups/filesystem/$mybackupname) duration=$((`date '+%s'` - $start))"


# Log to system log; handle this using syslog(8).
logger -t backup "$status"

Anyone see where I'm going wrong here?

As "That other guy" commented the solution here was to run the dos2unix convert command on the bash file:

sudo dos2unix /etc/init.d/backup.sh

and running it using bash command not sh command:

sudo bash /etc/init.d/backup.sh
