Create own bootable DVD
Hi,
I have installed a PIII - 733MHz as a Slackware server for my project in school. It's a database, ftp server with db4o that supports the data and all common files that are used in a java customer application. That's just some intro... My question now: the whole application and server is developed for a social organisation and they don't have any financial resources for hiring a IT expert or whatever. But like all technologie a server can go down, and it's not my intention to go and fix that server everytime it fails. So I want to create a backup dvd (iso) that can be put in by a member of the organisation and when the system reboots, the entire system will be reloaded exactly the same configurations as it has now... Is this possible? And if it is, is there any step by step tutorial? I'm not an expert in linux but also certainly not a beginner... SO I don't want to create a bootable dvd consisting of multiple install-iso's but a bootable dvd with the entire configuartion of my system as it is now... Thx in advance GekkeGwuido |
Have you tried here?

Only have heard of a full system backup into bootable dvd, from which you can reinstall.
You can backup your /etc dir, cause all settings are there. However, nobody will preserve all your other files (like executable ones) from deletion/corruption. |

The pair of programs mindi and mondo say that together they can make a bootable installable backup. I've messed with it a bit, but it didn't fit my needs, as it doesn't seem to be able to play well with dmraid. But, you might give it a try to see if it'll work in your situation. Install both of those programs and then run mondoarchive.

But you must understand that saving only config files won't let you to upgrade packages, because some of new packages could not work with old config files (deprecated functions, new storing paths, etc). What I mean is that restoring only config files without appropiate binaries does not give a guarantee to have a usable system.

use dd and write whole data to disc (dvd or external hdd maybe)
when somebody breaks something, you will use same dd to overwrite you can even create a script for a newbie user ./save_backup.sh ./load_backup.sh |

With any media where dd is.
You can create live cd with your backup. And then use dd. Or boot with slackware cd and then use dd to restore backup from another dvd or external hdd. |
So basically dd the drive to a image file, and place that on a live CD with the appropriate script to write it back to the drive. You could also do this with something like partimage or G4U/G4L, but I guess that would take more technical knowledge than these users have.
But the part I don't understand here, if you just restore the server to the way it was when you installed it, they are going to lose any data they added to the database. Certainly that is going to be a problem, unless they back that up on the client side? Finally...not to be too arrogant here, but once the server is setup correctly, there is very little chance that it is ever going to have a problem unless somebody is messing with it. This isn't Windows we are talking about here, were there are apparent random system crashes. The chances that an autonomous Linux server is ever going to have a problem that can't be fixed by a reboot is slim to none. I really wouldn't worry about it. |

I've managed to make a .iso file, but now it's way to big (6.7 Gb) to burn on a dvd. With dd I've created a .gz file that is approx 3.6 Gb... How can I burn this to a dvd? Or waht can i delete from the original slackware iso???

get slax frodo and copy your gz
