I agree. dd will allow you to copy an entire partition block by block. This is good if you are replacing a hard drive and want to keep the partition layout the same. Rsync is better for doing things like incremental backups. I use a home-grown script run from a cron job to do a nightly backup of my home directory to a second hdd on the same machine. It isn't a pretty script (in fact, it's pretty crude) but it does the job that I need it to do. It consists of only one line: rsync --logfile=/var/log/home_backup -Ca /home/<username> /backup/<username>. This just compares each file in /home/<usersname> with its corresponding file in /backup/<username> and copies any that are new or have changed, resetting the archive bit for each file. I also have set up the log file in logrotate so that it rotates the logs and keeps 5 days worth. There are probably plenty of flaws in this backup method (I wouldn't use it in a business situation - I'd write something a little more sophisticated or run a commercial backup solution) but for my needs at home it works fine. I hope this is of some help. -- ====================================================== Rodney Baker VK5ZTV [EMAIL PROTECTED] ====================================================== -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
