I don't see anything obviously wrong You have edited this in Microsoft Word which has inserted a few nasty "smart quotes" into it. Replace all smart quotes with ' and " in an actual text editor.

And definitely do a "dry run" first: Print filenames instead of deleting them.

I'm not sure how the pause helps you; once you hit it, it either deletes the right files or the wrong ones...

Code:
#!/bin/bash
# delete files oder than MM minutes if the size exceeds GG gb

MM=60
GG=3

# get size of directory
sz=$(du -s --block-size G  ./Backup_NVR | awk '{print int($0)}')

echo "Directory size: " $sz
read -p "Press [Enter] key to continue…”

if [ $sz -ge $GG ] ; then  # too big delete older files

       find ./Backup_NVR -type f -mmin +$MM -print
    find ./Backup_NVR -mindepth 1 -depth -type d -empty -print
fi

backup-manager(8)					      System Manager's Manual						 backup-manager(8)

NAME

       backup-manager - An easy to use backup tool for your Linux box.

SYNOPSIS

	 backup-manager [options]

DESCRIPTION

       Backup Manager is an easy-to-use tool for generating archives.

       It is designed with simplicity in mind for those who don't want an obfuscated tool for making tarballs.

       There  are  different  methods  for  building  archives: tarballs, incremental tarballs, mysql dumps, svn dump. You can also write your own
       method with a generic method that will execute a command and will archive its output.

       Every times you run Backup Manager, you can upload archives thanks to a couple of upload methods: through FTP, SSH or even with RSYNC.

       It's also possible to export your archives to removable media like CDR or DVD.

CONFIGURATION FILES

       Backup Manager's behavior is defined in configuration files. You can use different configuration files at the same time.  The default  con-
       figuration file is `/etc/backup-manager.conf'.

       An  example  should  have  been	provided  with	the  program,  most  of  the time it's installed in `/usr/share/backup-manager/backup-man-
       ager.conf.tpl'.

       If you want exhaustive details about how to  write  your  own  configuration  files,  please  refer  to	the  Backup  Manager  User  Guide:
       http://www.backup-manager.org/documentation/user-guide/

OPTIONS

       --version Show the version number.

       --verbose|-v Print what happens to STDOUT.

       --no-warnings Disable warnings.

       --help|-h Print a short help message.

       --upload|-u Just upload the files.

       --purge|-p Just purge old archives.

       --burn|-b Just burn the archives.

       --md5check|-m Just perform the MD5 checkup on the CDR/CDRW.

       --conffile|-c file Use an alternate config file.

       --force|-f Force overwrite of existing archives.

       --no-upload Disable the uploading process.

       --no-burn Disable the burning process.

       --no-purge Disable the purging process.
