Transfering files from one server to another.
My oracle database is generating archive logs. I want to copy those archive logs over to backup server on a regular basis. I know how to create an ftp job and I can put it in my crontab. My problem is that I don't know how to send the files just once instead of sends all the files in the directory over and over.
Example: I have archives 1, 2 & 3 when the cron job starts. It sends archives 1, 2 & 3 over to the other server. Now 6 hours later when the cront job runs again there are archives 1, 2, 3, 4 & 5. How do I make the program know that I have already sent over 1, 2 & 3 so that is only sends 4 & 5? I am thinking that if the ftp could return the contents of the directory on the backup server then some how compare what is in the directories of the two servers and only send over the difference that would solve my problem. I know that I can do a dir to find out what is over there but I don't know how to handle what comes back and then compareing them. Does any one have any ideas or am I on the wrong track entirelly? I appericate your help.

RDIFF-BACKUP-FS(1) General Commands Manual RDIFF-BACKUP-FS(1)
NAME
rdiff-backup-fs - Filesystem for accessing rdiff-backup archives.
SYNOPSIS
rdiff-backup-fs <mount_point> <repository> [repositories ...] [-option ...]
DESCRIPTION
rdiff-backup-fs is a filesystem in userspace that reads rdiff-backup archives and provides convenient access.
OPTIONS
--debug <0-4>
Run rdiff-backup-fs in foreground with given verbosity of debug messages.
-f, --full
Store information about all revisions in memory. CAUTION: this may take a lot of memory if your archive contains many revisions.
-l, --last
Displays files from the most recent increment as directories, each holding every version of the file. CAUTION: this stores informa-
tion about all revisions in memory and therefore may take a lot of memory if archive contains many revisions.
-c <n>, --caching <n>
How many files retrieved from the rdiff-backup archive may be cached by filesystem. By default rdiff-backup-fs will cache up to 10
files. If this switch is set to 0, no caching will be done.
-r <n>, --revisions <n>
How many revisions should be stored in memory for on demand revision retrieval. By default rdiff-backup-fs will store up to 10 revi-
sions in memory.
-d, --directory <path>
