Hard drives will fail, files will be corrupted, laptops will be stolen, and data will be mistakenly deleted. While good maintenance may help avoid some of these scenarios, in the end it pays to have a data backup.
Backup refers to making copies of data so that it is available to restore the original data in the event of a data loss. Backups are useful primarily for 1) restoring a computer to an operational state following a disaster (called disaster recovery), and 2) restoring small numbers of files after they have been accidentally deleted or corrupted. As long as new data is being created and changes are being made, backups need to be updated. How frequently and which files are backed up is determined by the user.
Bucky Backup offers an inexpensive and convenient way for individuals, departmental local area networks and campus applications to protect their data and recover it if needed. It provides high-quality, industrial-strength insurance against the loss of irreplaceable data. Bucky Backup provides point-in-time backup so that if an individual deletes or corrupts a file, for instance, the data can be recovered.
UW-Madison also provides 50 gigabytes of free disk space to UW-Madison students, faculty and staff, which can be used to back up important files, using a service called Box.
