A Simple System Back-Up Suggestion?
I'm running RedHat ES 4 as a test server for web development. I am relatively new at administering a Linux Server on my own, having relied on trained professionals at third parties in the past.
I am looking fo a painless :-) way to back-up the operating system once I have it configured. I have the local network working, as well as Perl and MySQL. I am planning on loading Tomcat and the Java JVM to run Java Server Pages. What I'm looking for is a way to save the system in a given state so I can reload it in the event of a drive failure. I don't believe that I need a mirror of the system, as this seems like it may be a little more difficult to set-up. I would be happy with a solution that required me to re-install the operating system, then overwrite the system files with the back-ups that I made. This is the gist of my question... If I copy file system folders to another drive (I added another hard-drive to the box to be used for back-up) with the intent of using these to restore the configuration of my server, can I overwrite a newly installed file system with these folders and expect my server to be in the state that it was in when the back-ups were made? Any suggestions would be greatly appreciated. Thanks, Bob |
You have 2 easy options. If the drives are the same size, you can do software RAID between them, so the 2nd disk is a copy of the first. Even easier is to set up the wonderful http://backuppc.sourceforge.net/to backup whatever you tell it to backup. Of course, the backuppc solution can only run on a linux box, so if you only have 1, it is backing itself up, and fdoesn't help much in the even of a catastrophic failure, but if you just want the ability to restore yesterday's files over todays, it rocks. I deploy that all over.
Peace, JimBass |
