Q: How much free space do I need on the InterMapper Database disk?
A: In general, InterMapper Database requires an amount of free space that's based on the total size of the database. To be absolutely safe, you should have as much free space as the size of the database itself. In practice, you can get by reserving as much space as the largest index: this tends to run about one-third of the total database size.
This space is used for temporary storage during daily and weekly maintenance, when the database compacts and re-organizes its tables for optimal performance.
