Linux Gazette: Backup for the Home NetworkDec 05, 1999, 18:49 (0 Talkback[s])

"Everyone has a backup plan. Unfortunately, most of us use the "No Backup" plan...."
"For the home network, you have to have some sort of backup plan. Although hard drives will crash, the real value in the backups is restoring accidentally deleted, or changed, files. Sooner or later you will delete, or change, something important, and without a backup, you could render your computer unbootable. I am embarrassed to admit this, but I actually deleted /root on one occasion. Note: backups should be considered compromised if you have been cracked. Backup plans need to be simple to implement or they will not get done - especially at home. A backup plan for home should cover two areas: how much are you going to backup, and how are you going to do it with the least amount of effort."
"How much to backup: I try to minimize the amount I backup because storage space costs money. I only backup directories, not the entire file system. Most of /usr and /opt are on the install cdrom, so if the hard drive crashes, I will install them by default with a new install. /etc and /home are the most important as they contain the configuration and custom settings files. Your backup plan should include full backups of the selected directories every so often, and then backup just the changes (incremental backups) daily."
