| Does the clone tape contain savesets other than the e-mail savesets
that have a retention period of 3 days.
What client is the D:\ drive on? Does that same client have any
other retention periods that refer to it, i.e. for other disks?

Yes, We set up a "Long Term Clone" group and a "Short Term Clone" group.
The e-mail savesets are part of the "Short Term Clone" group. The e-mail
servers are the only servers that have the 3 day retention policy.
>What client is the D:\ drive on? Does that same client have any

The e-mail servers are setup with Drive C which contains the operating system
(NT) and Drive D contains the e-mail data. We have defined the e-mail
servers to backup drive C and the REGISTRY: once a month and then drive D to
do a Full backup every night.
Thanks,

| The clone volume won't be marked recyclable automatically until
all of the savesets contained on that volume are recyclable. If
the volume contains savesets with a longer retention policy than
three days then the volume won't be recyclable until the longest
of those policies have expired. You can manually set the
volume recyclable if you don't want to wait that long.

| Thanks for the information. We will change our clone policy so only the
email backups write to the short term clones. I will test this out and keep
you informed on how this works.
But I still can browse my email servers for more than 3 days. If I go to a
email server and run the NetWorker User, click on Recover, click on the D:\
and then click on View and select Versions it shows all the backups. I
thought that it would browse only three days. The version dialog box shows:
D:\
Size Mod Time Backup Time Location
<vol> 05-08-97 1:03a JEMA.001 at jb1
<vol> 05-07-97 1:03a JEMA.001 at jb1

It shows the location as the email volume and if you look at JEMA.001 tape it
shows only the email servers, bootstrap and file index.
What can we do to get this browse policy to show only 3 days? Also the
retention policy for this tape should also be 3 days.
The tape pool JEMA.001 - JEMA.003 stays in the autochanger all the time for
fast recovery, we clone each night and take off site the clone tapes. Based
on the the response of retention not being recycled until all the save sets
contained on that volume are recyclable, then do you mean that the tape pool
JEAM.001 - JEAM.003 will never recycle because a save set is being added
every night. If this is the case, we will have to write to a seperate
JEMA.xxx every night and remove every day and then rotate the tapes every
fourth day. Is this correct?
Thanks,
Allen

| Two things can be used to stop saving to a partitally filled
tape. First set the volume 'read only' after the desired number
of days backup. Second look at setting the volume expiration
so that it is only used for the desired number of days. Both
solutions take almost daily intervention, for the first to
change the state, for the second to relabel a new tape each
day.

| But we want all this automatic using the retention and browsing policies. We
can work around the retention policy by swapping the email tape every day and
putting them on a four day rotation. When the tape is swapped back in on the
fourth day, the retention should be expired and then the tape should be
recycled. If I am wrong about this please let me know.
But we are also concerned that the browse policy is not working.
Thanks,
Allen

| Data stays browsable until the tape is recycled. The browse
time is the earliest that the data can be removed from the
indexes without manual intervention.
If the tape is still apendable I don't think it will be automatically
recycled. I can't see that is any harder to swap tapes then
to change the tape status. I.E.
nsrmm -o readonly MAIL.001
One more thing to consider, it you never need to restore single
files, change the mail group to not write to the client index.
The data can still be retreived via the saveset recover since
the save set will still be listed in the media index. If you
do this you can go ahead an let the tapes fill and let the
normal automatic recycling work.
