A couple of items to consider. 1) "cp" may not be the best choice for this. "rsync" is a bit smarter about only copying what has changed. 2) Bob Webber had a good suggestion about making sure the source and destination trees really are different. The "--dry-run" argument to rsync may be helpful here. Think of it as a "diff" for trees. 3) This method doesn't give you much opportunity to recover beyond the last backup. e.g. You delete a file today. The "backup" runs tonight. Tomorrow you realize you need the file that was deleted. As you said "simple backups" this may not be an issue at the moment. However you may want to consider NOT deleting files on the target or perhaps keeping a few days worth of rsyncs. - Paul Beltrani _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
