Thanks! That did it.
/usr/bin/rsync -av --exclude=".*" -e ssh /home/ 192.168.0.22:/home/ My next step will be to brush the dust off of my Perl book and write a crontab script to backup nightly. Question: I may not be using the term "backup" absolutely correctly. The destination server is a "standby" server. This is if the source server fails, all I have to do is change the router to point to the standby server. These are in a home office and I do not consider myself a system administrator; just someone who knows enough to keep the server running (it's main task is FTPing). Do you have any suggestions about using rsync as I am doing?
Todd,
If all you want to do is mirror the main server to the backupserver, your command is almost correct. You'll want to add --delete on the commandline. This will cause rsync to remove any files from the destination before sending them from the source. This will create a mirror of your main server to your backup server.
You don't need to go to all the overhead of running Perl to crontabthis up. Just drop your rsync command into a file, make it executable then add it to root's crontab file. It'll run just fine after that.
One other thing nonrsync related - top posting, and sending HTML tothe list. Makes it hard to respond to your questions. Just remember to use text only, and post responses at the bottom of your emails. Things just tread much easier from top to bottom.
Thanks!

Yes, the bottom post vs. the top post is a continual problem for me since my business accounts ask for top post (almost demand it) and Thunderbird does not have an option for each email address as it does for email mode. I'll try to remember to swap it back and forth.
Concerning the --delete switch, if I use it, will files created by a user on the destination server remain? Though it is a standby server, there are times when it is used by staff.
The main reason I will use Perl is to create the backup files of the Interbase databases and then scp (or rsync) them to the other server.
Many thanks for the tips....
Todd
Delete will remove files on the destination that aren't on the source. So that option will not work for you.
