Contrary to one opinion in this thread, most of the "enterprise" (and very large government departments) I've worked with *do* use DVDs for backups to some degree. They're also often used by SMEs, with bank and security lockboxes used to for secure offsite storage. Tape and online backups (usually outsourced to storage companies) are the first level of backups, but often DVDs are used as a second level of data security. The advantages being that retrieving backups from DVDs doesn't incur an additional service fee; they provide an added layer of data security, and independence from business wide backup scheduling. Belts are good, but for full pants security belt and suspenders is better. As Ralf points out - modern optical storage media is not very reliable. *If* you don't implement the same (ITIL?) practices you would/should with magnetic media - that is, check it. You should also use archive quality optical media for your backups for best results. cdck, and qpxtool are useful for checking your optical media backups before trusting them. dvdisaster is my tool of choice as it can add additional levels of error correction. As with any backup - it's of little value if kept onsite unless locked in a fire-proof safe (though I've known "professionals" who kept backups on the same machine they're backing up!). An additional consideration with optical media backups is age deterioration, so storage conditions and media design will determine backup rotation schedules. Note: all the tools I mentioned are in the Debian repository and IMO are as good, or better, than the commercial alternatives.
