Backup planning
When an important data is lost, we need Backups. There are many reasons for data loss. Hardware failure or accidentally deleting file is the main reason for data loss. Backups help to preserve the data & can help in the above situation.
Planning a backup is very important. A well planned backup saves time & money. Which files are irreplaceable without a back up. Irreplaceable files probably include those in users’ home directories (including /root), and configuration files, such as those in the /etc/ directory.
Which files are on removable drives, such as cd s or floppies. Since you probably do not need to back up removable drives, you might unmount them before doing a complete system backup.
Which files can be easily replaced by installing a package or doing a selective install or upgrade of the operating system. You can save time and storage space by not including these files in a backup.Which files are unnecessary or dangerous to backup. For example, files in /tmp are probably unnecessary, while restoring some files that are in the /proc directory could crash the system.Whether to compress files using gzip or bzip2 . Compressing saves space, but adds another step to the backup. Also, while compression is generally reliable, it creates another stage at which the process can fail.Whether users are responsible for backing up their own files. Since only the root user has full permissions for all files on the system, usually backups are best done by the root user. One should give top priority to backups as you never know when you will loose data that would be worth a Million Pounds.
