Data Backup Methods
Four fundamental backup methods are: full backup,
To choose a data backup method, you must first weigh three factors:
the capacity of your backup media, the period of time available for
your backup, and the level of urgency expressed by you or other
users when a file restoration is necessary.
For example, conducting full backups on a daily basis will
require both high number of media and a long period of time.
But doing so will facilitate rapid and easy restoration because
you will need only one media to pull data from. On the other hand,
weekly full backups combined with daily incremental backups will
conserve media and shorten the daily backup period, though data
recovery would require the last full backup and each subsequent
incremental backup up to the most current - a process that can
seem to take forever when there are needy users waiting for a file.
After you select a backup method, you need to schedule backups and pick
the most appropriate rotation scheme for your organization and network
needs. Ideally, this reduces media costs and extends the longevity of
your media, while ensuring that every file is protected.
