# Function Task Duration Task Refer to (hrs) dependency 9 Defragment tape Reclaim 1.0 volumes in volumes sequential storage from pools. OFFDIRS. 10 Reclaim 3.0 volumes from OFFDATA. None None 12.2.5, "Defining a reclamation schedule" on page 383 11 Reclaim 3.0 None volumes from TAPEDATA. 12 Enable statistics. Audit 0.25 licenses. None 12.2.6, "Defining a licensing audit schedule" on page 385 We recommend that no other schedules or administrative tasks are performed during client backups, so that backups have the maximum system resources available to them to minimize the backup time. Running administrative tasks or schedules during the client backup window will only take processing cycles away from the backup tasks. 12.2.1 Defining an off-site backup schedule When the client backups are complete, the new data in the primary storage pools should be copied to a copy storage pool. The copy storage pool tapes, along with the database backup tapes, should be taken to a secure off-site location or vault. The copy storage pool and database backup tapes are referred to collectively as the off-site backups, and will be used to restore your environment in the event of a catastrophic failure or disaster. Flow of events The order of execution of these tasks should be as follows: 1. Check that there are no running sessions with the clients. When you back up the primary storage pools and database, you want to make sure that you are capturing an up-to-date copy. If a client is still backing up its data, wait until it is done before starting the off-site backups. Chapter 12. Scheduling 377
