My NetWorker Admin guide stated the Auto Media Management "Recycles volumes 
eligible for reuse that are loaded into the device."  I assume a volume was 
eligible for reuse when it expires and becomes recyclable.  Thanks for the 
update!  

I am running 7.4.3, the most recent version.   I have a retention policy 
associated with the clone pool of 1 year.  The clients have a retention/browse 
policy of 2 months.  There is no retention policy associated with the full 
backup pool.  Up until the clone operation, the retention period of 2 months 
was observed.  After the clone, the volume expiration was 1 year. 

Why would the volume expiration differ from the save set expiration?  If the 
volume is full, the expiration of the volume should be equal to that off the 
save set with the longest retention.  Correct?  The volume expiration for my 
latest full backup volumes is 2 months, the monthly clone operation has not run 
yet.  When it does, I suspect the volume expiration will be 1 year rather than 
2 months.  Are you saying the NetWorker's expiration is not relevant?  

I am aware that dependent backups (incremental) must expire before save set 
expires.  However, I am not sure what you mean by "giving the effect that a 
full does not expire until the next oldest full reaches it expiry date."  Can 
you break this down a bit?  My understanding is such:  I have a 2 week 
retention policy with incremental monday-saturday, full on sunday.  The first 
backup will not expire until 3 weeks because the incrementals are dependent on 
the full backup.  

Running the mminfo commmand, I found the following information pertaining to 
this inquiry:  

- Backups on 10/31 have a ssretent of 12/31/2008, with a clretent of 12/31/2008

- Backups on 11/01 have a ssretent of 11/2/2009, with a clretent of 1/1/2009

This information is misleading to me.  The backups on 11/01 shouldn't have a 
retention of 11/2/2009.  The clretent should be 11/2/2009, not the ssretent.  I 
am looking at a volume from the full backup pool.  

Looking at the volume from the clone pool I found that the ssretent and 
clretent are the same for 11/01, which is 11/2/2009.  

Any ideas on why this is backwards for the full backup volume?
