Hi,

I'm a little confused about retention times definitions for the 
following situation:

I am doing daily backups (Full, Diff, Incr in monthly cycles) for all of 
my clients. I want to keep all these backups for 12 month. 8 weeks of 
these 12 month the data should be kept on a disk device (pool DISK). 
Then migration should take place and the data should be kept for 
additional 10 month on a tape device (Pool TAPE). After migration the 
data should be purged/deleted from pool DISK.

I defined the following Retention Times:

For each job (going to pool DISK):
    - File Retention = 9 weeks
    - Job Retention = 9 weeks

For pool DISK (Next Pool = TAPE):
    - Migration time = 8 weeks
    - Volume Retention = 10 weeks

For pool TAPE:
    - Volume retention = 12 month

Is this correct? Will I be able to restore 10 month old backups from tape?

-- 
Regards
Christoph
