There are many factors that would decide this. One of them woula be the hosting 
environment. In ours, we have a 3584 library with lto Gen 1 drives and they are 
cleaned about every TB of data, roughly.

Have an ADIC I2k with 4 fiber LTO2 drives running TSM in a Windows 2000
environment.  How often should the tape drives be cleaned?  Backup 50-60
GB nighly and that should be close to 80 plus in the near future.
