For example, if you have a backup group A (all clients have a browse and
retention policy = 3 months) and the backup server is inside this group.
This backup server has a browse and retention policy = 1 year in another
group B, you'll have a retention of 1 year for bootstraps and indexes in the
group A. To do : change the policies of backup server.

If you discover another solution. Hold me informed !!

Hello,

you are right, there are still browsable savesets on the volume as mminfo
shows:
mminfo -a -v 000098
 volume        client          date     time        size ssid      fl   lvl
name
000098         jusstusd001   18.01.2004 01:58:53 2157 MB 185195329 cb  full
D:\NTBACKUP

But this saveset is already ready for recycling:
C:\>mminfo -q "ssid=185195329" -r
"sscreate,ssbrowse,ssretent,state,fragflags"
 created  browse   retent     fl
18.01.2004 18.02.2004 18.02.2004 E  hE
18.01.2004 18.02.2004 18.02.2004 E  mE
18.01.2004 18.02.2004 18.02.2004 E  tE

Now this is a saveset with "E" and with "b"; how come?
Is there somewhere a saveset (still browsable) that depends on this one? How
do I find this saveset?

We ponder this quite often as our tapes come up for recycling.   Networker
is usually right though and seems to know better then us.

You can
do a mminfo -a -p -v 000098  and it will show you the retention of each
saveset on the tape.   Still you may find all the expire/retention dates
have pasted.   You can do a mminfo -a -v 000098 and look  for savesets
with a "E" flag as recycle and no "E" (still browsable?).

In short Networker keeps track of dependencies of the save sets; even though
all savesets on the tape have reached their retention period there are still
other savesets that depend on them..ie. incrementals or level 9's that
depend on a full level saveset.    When these other dependent savesets reach
their retention then Networker will recycle/expire the saveset on the tape
in question and thus the tape.
