I’m setting up a backup system on my linux web server. The backup will be done nightly to an external hard drive. Typically, what is the best way to handle backups? In mind I see two possibilities. Back up the complete server system including operating system files and configs (everything in the / directory), or just backup the website files in the user directories individually (example: backup /home/www). Is one way or the other bad practice?

Thanks for your help.

Just backup documents only. Space is a commodity and you might find you fill it up which can get costly.

Rebuild the operating system and then restore the users’ files if you have any issues.

One of the benefits of using a VE such as OpenVZ or Xen is that you can backup and restore an entire server with 1 click, and can be done automatically when a fault is detected. Just something to consider!

we have oracle 9i database but after crash down of server we are unable to get full recovery of database. will you pls advice us what is the best practice we follow to backing up our oracle 9i database so in near future if same problem persist we can able to get full recovery of database.
dear sir
we have only one real time server which we are using for backing up our oracle database.we do not have any specific back up server. so what type of good back up practice we follow which will able to give full recovery.awating for your reply.

Let me know what happen with your Backup server if you have one,
Its a good practice having a backup server and a real time server, if any thing happen with real time server you can recover the data from the backup server and continue with the work. check the following link to know about the backup and recovery principles http://download.oracle.com/docs/cd/B10501_01/server.920/a96519/toc.htm
