System backup/snapshot
Hi, I need some mechanism in/for debian to be able to make whole system backup and restore. Why ? I want for example perform some updates on the system that may be upgrading/changing of debian packages, some files or firebird database. If one of the update tasks failed i want be able to restore complete previous system before all updates occurs. Is there are general solutions for this? Thanks, Pavel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Do the dist-upgrade. Test the changes. If I don't like it. partimage+restore. The disadvantage is that you cannot be on the system you backup. If you want to do that use mondo, it creates bootable CD's, but that process takes a lot longer, the advantage being you can do that on the current system and boot the CD(s) anywhere else, not so with partimage.

I had this reference in my links. http://www.mikerubel.org/computers/rsync_snapshots/ On a related topic -- I understand there's a bunch of a failover systems available, but I often would like to have a backup machine that can take over as a primary machine if the original primary machine fails. /etc/ has configs for both application level services (Apache, DNS, etc.) but also has hardware/machine specific settings. So, I've been thinking of trying a setup where services like Apache that instead of using /etc/apache they use /etc/services/apache (and /etc/services/bind, etc.). Then /etc/services would be a symlink to various different configurations (e.g. /etc/primary /etc/backup). Then use rsync to keep those the same on both machines. The problem with that is the /etc/init.d/ scripts are hard-wired to use /etc so I assume an update to an init.d script would overwrite that setup. -- Bill Moseley [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
