I can recommend ReaR (Relax and Recover) for migrations and cloning systems. I have been working wit the Relax and Recover project for the past few months together with a colleague and it now covers a lot of situations: - HWRAID (SmartArray), SWRAID, DRBD, partitions, encrypted partitions, LVM - It supports bootable tapes (OBDR), ISO images and USB media - It supports backup software for restoring (like Bacula, TSM, rsync and others) - And it can also take care of backups (using rsync, tar) using different solutions (NFS, USB, Samba, ...) - It's modular, so with little effort you can implement your own workflow or use-case However I would stress to test a complete disaster recover scenario for your systems (different technologies) in order to understand if everything is supported. You don't want to realize a problem in disaster-mode :) But for the use-cases we have, the current trunk is very usable and flexible to support restoring on different hardware. Even with different controllers/disks etc... During recovery you can still adapt the layout and make changes to your wishes before restoring. We are preparing a new stable minor release (without the new layout code enabled by default), but after that release there should be a new major release covering everything I mentioned by default. If you need more help, feel free to join the ReaR mailinglist on sourceforge and ask your questions :) http://rear.sourceforge.net/ And if you happen to go to LinuxTag, we're having two discussion sessions for developers and users on Wednesday and Thursday. -- -- dag wieers, d...@wieers.com, http://dag.wieers.com/ -- dagit linux solutions, i...@dagit.net, http://dagit.net/ [Any errors in spelling, tact or fact are transmission errors] _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
