Here are the some points for Good Administrator
* Backup Everything regularly and validate it.
* Avoid GUI interface & CLI for every task.
* List out the task (daily, weekly, monthly) and make it automate.
* Never change the root shell, unless you have an alternative root account set up!
* Validate the Process
The simplest solution to validate data is to restore from your backup media and compare that to the existing data. Most simplistic is to run a ‘sum’ on the files to compare. If the data is more dynamic, run a sum on the files in the backup before they get backed up and include that in the backup. Restore to a different directory and check it against what is restored.
To generate a checksum file:
find . -type f -print -exec sum ‘{}’ \; > checksumfile
then back it up. Restore it someplace, run the same command (but put the output in a different file!) and diff the two checksum files.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
