I think you are asking: 'how to stop deletion of files on a file server until after the file has been copied'

One way: rename each file right after you copy it over.
You can do this several ways example using your current pid
Code:
# create a special local directory
pid=$$
local_dir=./myfiles/${pid}
test -d  $local_dir || mkdir $local_dir
cd $local_dir
sftp someplace.com
username password
cd /path/to/files
mget files*
bye
find . -type f -name |
while read fname 
do
         sftp someplace.com <<EOF
         username password
         cd /path/to/files
         rename "$fname" "$pid"
         bye
EOF
        mv "$fname" /path/to/permanent_local_storage/directory
        rm "$fname"  # get rid of local duplicate. 
done
sftp someplace.com <<EOF
  username password
  cd /path/to/files
  rm "$pid"
bye
EOF

Your remote directory has one file left because you kept renaming every file you copied to a pid number. Remove it when you are done. This can be improved in lots of ways.

Note: the EOF that ends a heredoc in this example has to be LEFT i.e., column 1

EDIT: I see Rudi had the same idea.
It can float if the first one for the heredoc is <<-EOF

NAME

       sftp-server - SFTP server subsystem

SYNOPSIS

       /usr/lib/ssh/sftp-server

DESCRIPTION

       sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer.

       sftp-server is a subsystem for sshd(1M) and must not be run directly. There are no options or config settings.

       To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config:

       Subsystem   sftp     /usr/lib/ssh/sftp-server

       See sshd_config(4) for a description of the format and contents of that file.

       There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd.

EXIT STATUS

       The following exit values are returned:

       0        Successful completion.

       >0       An error occurred.
