Local Backups And Data Quality
Most large organizations already follow a corporate backup policy. However, for individual developers, maintaining local backups before major changes can be critical in avoiding the embarrassment of calling an IT manager for help. Every developer has their own way of accomplishing this; while local backups are necessary, their actual implementation is a matter of taste. If accuracy and ease of restoration is the primary concern, full backups may be taken and stored locally. If space is a concern, differential or record-level backups may be taken.
