Plan on performing some level of archiving daily. Under extreme circumstances, you might even want to perform archiving more than once a day. For example, you might want to archive files three times a day before a major release or during a major bug fix phase.
The three levels of archiving are:
- Level 0 is the baseline archive.
- Level 1 includes all changes since the last Level 0 archive.
- Level 2 includes all changes since the last Level 0 or Level 1 archive.
Here is an example of an incremental archiving strategy. Each archive level is performed according to the following schedule:
