You do not need to have PermitRootLogin Yes The forced-commands-only option means that you can only run the commands specified by the matching record in your authorized_keys file. This is from one of mine:-
Code:
command="/usr/local/bin/sysbackup" ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAsNaXL2++..........

This means that you can keep Security happy, because you still prevent login with ssh as root.

I suppose another way would be to use NFS and mount the ServerB directory on ServerA. You then could copy the data much more easily, as though it were a local resource. Do you know how to do this? It's a bit like mapping a network disk in Microsoft terms. This might give you security concerns though, as the data will be available on ServerA (subject to permissions) and you need to be careful with ownership. The files/directories ownership are stored as the UID & GID numbers and that can vary between servers, e.g. a file owned by bob, UID 1024 on ServerB may appear to be owned by sue on ServerA if sue has UID 1024 on ServerA.


Not sure if either of these suggestions helps or causes more headaches.

How do they seem to you?

backup_delvolset

BACKUP_DELVOLSET(8)					       AFS Command Reference					       BACKUP_DELVOLSET(8)

NAME

       backup_delvolset - Deletes one or more volume sets from the Backup Database

SYNOPSIS

       backup delvolset -name <volume set name>+ [-localauth]
	   [-cell <cell name>] [-help]

       backup delvols -n <volume set name>+ [-l]
	   [-c <cell name>] [-h]

DESCRIPTION

       The backup delvolset command deletes each volume set named by the -name argument, and the volume entries each contains, from the Backup
       Database. The backup listvolsets command lists the volume sets (and their volume entries) currently defined in the Backup Database.

CAUTIONS

       Deleting a temporary volume set is possible only within the interactive session in which it was created. Exiting the interactive session
       also destroys the temporary volume set automatically.

OPTIONS

       -name <volume set name>+
	   Names each volume set to delete.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
	   the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
	   details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command deletes the volume set called user and all volume entries in it:

	  % backup delvolset user

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
