Backup

Backup Book

How to Backup is a free online mini-book explaining basic ideas about how to backup your network, backup technologies, and backup strategies to keep your systems online, and your data available.

Backup Laptops with a Dock

If you have a laptop that you travel with, consider getting a dock for your office desk. If your laptop isn't dockable (because it's a "home" laptop computer), then, get a universal dock.

File naming conventions for websites

Websites are archives. A website that isn't an archive is one that displays a lot of "404 errors" - file not found.

File naming conventions for routing documents past multiple editors

In a typical office, several people have to read a document - the writers, the editors, a manager, the signatory to the document, and possibly some artists.

File naming convention with dates

The file naming convention I use starts the name with a date: YYMMDD-file-name.ext

Archives and Archiving Files and Documents

Archiving is different from backups. Think about them separately.

An archive is an organizational strategy for data.

Backup to External Hard Disk or USB Flash Drive

A simple, transparent way to backup a personal computer is with an external hard drive or USB flash drive.

You don't need special software to do this - just copy the files.

Database Backup

The correct way to backup a database is to use a "mirror" or "replica" of the database.

Subversion (svn) as a Backup

If you're programming (or managing programmers), you can use Subversion or any other revision control system as a backup.

Secondary Backups

It's a good idea to run two sets of backups. For one, it's possible that the backup software can fail, leaving some data unsaved.

Full Backup

A full backup is a backup of all the files. It's used in contrast to the incremental backup, which is a backup of files changed since the last backup.

Incremental Backups

An incremental backup is a backup of all the files that have changed since the last backup. Typically, you perform a full backup, then a series of incremental backups.

Backup to Floppy

Backing data up to floppy went out with the 1990s. Hardly any computers have floppy disk drives anymore.

Backup to CD-R and CD-RW

Backup to CD shares a lot of problems that backup to DVD has, with some interesting differences.

Backup to DVD

Creating backups on DVD-R or DVD-RW allows you to store up to 4.8 gigabytes of data (or 2.4 if you use single layder DVDs).

The main advantages:

  • low cost
  • archival, by default
