Selecting Media for Backup
Chapter 4 121
Media in poor condition are not used for backup. Media in fair condition
are used only if no media in good condition are available. Media in good
condition are sorted to use the one with the least number of overwrites
first.
Media are always selected first from the specified pool and (optionally)
from the free pool.
