Previous thread (which includes sample script and some replies) is:
https://www.unix.com/shell-programmin...scp-files.html
Can you tell us what Operating Systems and versions are involved?
Do you have administration rights over the target computer(s)?
Are you trying to make a choice between "ftp" and "scp" or are you trying to get both working reliably?
For automated "ftp" we usually transfer the files under a temporary file name and then rename the whole batch at the end of the file transfer (but still in the same ftp job). I have never seen a partial "ftp" where a subsequent command in that same ftp job is still executed. Tested this technique to destruction including rebooting computers, pulling the lan cable, killing processes etc. .
If your "ftp" program does not have a timeout, you need to implement a timeout process.
For dodgy networks or critical data we also create and transfer a control checksum file after the main files, then get the remote system to create a matching control checksum file, then transfer the new control checksum file back for comparison. Have used this technique for migrating large numbers of user accounts to a barely-compatible unix platform.

ftpconfig
ftpconfig(1M) System Administration Commands ftpconfig(1M)
NAME
ftpconfig - set up anonymous FTP
SYNOPSIS
ftpconfig [ftpdir]
ftpconfig -d ftpdir
DESCRIPTION
The ftpconfig script is executed by the super user to set up anonymous FTP. Anonymous FTP allows users to remotely log on to the FTP server
by specifying the user name ftp or anonymous and the user's email address as password. The anonymous users are logged on to the FTP
Server and given access to a restricted file area with its own file system root. See chroot(2). The FTP area has its own minimal system
files.
This command will copy and set up all the components needed to operate an anonymous FTP server, including creating the ftp user account,
creating device nodes, copying /usr/lib files, and copying timezone data. The passwd and group files set up have been stripped down to
prevent malicious users from finding login names on the server. The anonymous file area will be placed under ftpdir. If the ftp user
account already exists, then the current FTP area is used, and the system files in it are updated. All other files are left untouched. This
command should be run to update the anonymous FTP area's configuration whenever a system patch is installed, or the system is upgraded.
OPTIONS
-d Create a new or update an existing ftpdir without creating or updating the ftp user account. Use this option when creating guest
FTP user accounts.
OPERANDS
The following operands are supported:
ftpdir The absolute pathname of the directory under which the anonymous FTP area is set up.
EXIT STATUS
The following exit values are returned:
0 Successful completion
1 Improper usage of the command
2 Command failed
