It is possible that the expense can be so great that it drives the company out of business. An archival backup is one that is kept in an archive for long term storage. Archival copies are particularly useful for audits or cross-referencing long term information. In UNIX systems, a cron job can be created that automatically performs a periodic backup. A temporary backup is one that is kept for a short period of time.
Organizations are unlikely to be able to keep every single back up made.
The basic rule of thumb is to maintain at least three copies of a backup. An off-site copy of applications and data can be essential for recovery from a major disaster, such as fire, hurricane, tornado, earthquake, flood, or terrorist attack. Keeping the off-site copy at a distant location saves the data even if there is a large scale disaster. If your organization doesn't have a distant office or branch that you can trade back up copies with, you may want to consider such options as a data storage or archival business, a bank safe deposit box, or a law office. There are a lot of arbitrary backup policies that can be imposed.
