Re: Questions with rsync
This is a very useful thread for me to follow. You asked some interesting questions that led to answers with complete rsync scripts provided. That's what I call a really great response! It does help if you read `man rsync` and the web resources carefully. They can answer a lot of questions. You may want to read a copy of the book Backup and Recovery by W. Curtis Preston. It was published by O'Reilly in 2007 and might even feature current technologies...and it is available from Amazon. Preston wrote an earlier book with almost the same title, whuch is out of print. That one is Unix Backup and Recovery and I have it here. http://www.backupcentral.com/ Bob On 06/13/2009 10:22 PM, gmspro wrote: --- On Sat, 6/6/09, Mail Listsli...@sapience.com wrote: From: Mail Listsli...@sapience.com Subject: Re: Questions with rsync To: Community assistance, encouragement, and advice for using Fedora.fedora-list@redhat.com Cc: GMS Sgms...@yahoo.com Date: Saturday, June 6, 2009, 6:18 AM On 06/04/2009 06:28 AM, Steven Stern wrote: On 06/04/2009 12:53 AM, GMS S wrote: mv backup.8 backup.9 mv backup.7 backup.8 mv backup.6 backup.7 Have you tried rdiff-backup ?

I have a file called dirlist which is the list of root level directories I want to backup, this is coupled with a shell script (rsync_backup.sh) which runs my desired rsync command for each dirname found in the dirlist file. I also have a restore shell script (rsync_restore.sh). I use this to backup my Fedora10 laptop before I run any updates. I have had to go back and run the restore when updates caused video issues, the restore worked flawlessly.
