As it is supported that clone copy to have a different retention
the backup copy may have, then, given that,
I am confused with ssretent and clrentent fields :
1) why/where does clretent of 16/02 come from for backup copy ?
I'm not sure. I believe it has to do with the way that your retention of
"1 month" is defined in NetWorker. What is the definition for "1 Month"
in your NetWorker configuration? If it is not that, is there a
retention defined for the pool that L50000 is a member of? If that is
not it, someone else will have to educate both of us.
2) When will be marked recyclable backup copy ?
12/02 as per original SSRETENT and CLRETENT or
12/07 as per new SSRETENT ?
Each clone (including the original copy) is marked recyclable when its
clretent is reached. So, the original backup copy will be marked
recyclable on 16/02 (per your mminfo output).
3) When will clone 1 copy expire ?
12/07 or 12/08 ?
CLONE1 will expire on 12/07.
Am I correct assuming it as just a ?display? feature,
SSRETENT being just overwritten and media management
has to rely on CLRETENT / volexpire fields ?
SSRETENT will take on the value of the CLRETENT that is the furthest
out. When CLRETENT was added, SSRETENT was changed to be the date when
all clones of the SS will finally have expired. The original backup
copy is now considered to be a clone. Each copy is expired when its
CLRETENT date is reached.
