Browse period equal to Retention period?

Browse period equal to Retention period?
November 16, 2018 08:59AM
I am confused. Per my last email, I changed the retention date for some
old savesets, so they would expire, and so reduce the size of the index
files on disk. And to make sure that they got processed now, I did a
"nsrim -X" after setting the new retention time via script.

And what I noticed is that I sometimes see a message "69940: Only 1 Full
saveset exists for saveset xxxx. Browse period equals retention period".

Now, that's entirely possible, as I use a script to query savesets in
certain date ranges, and set the browse and retention times that way
(basically, find EOM savesets and given them an extended
browse/retention).
And it's entirely possible that at some point in the past, I may have
inadvertently set the browse time to be the same as the retention time,
using that script.

But: is this a warning? An error?

If an error, I can't think an easy way to fix it. I'd have to do some
fancy, complicated mminfo, extract out the offending savesets, and run a
new script to set the browse to be a day earlier than the retention. Or am
I wrong?

In regard to: [EMC-DataProtection-L] Browse period equal to Retention...:

You would have to ask EMC support. The message doesn't include "warn" or
"err" anywhere in it, so it's hard to know developer intent. It seems
more like a warning or informational message to me.

Such is obviously an older message (it exists since a while). See for example here:
https://community.emc.com/thread/217008?start=0&tstart=0

I think that this is only a general info or a warning. However, I am not sure how to read it:
- I might point to the fact that there is only 1 full for a save set which builds up when you run the probe (savefs)
command. In other words NW wants to inform you that you do not have at least a second full yet and you better create
one by running at least another full.
- However, you could also understand it in the way that you only have 1 full copy of an existing NW backup save set
which has already been created. This would mean:
- a second instance (at least one clone) is missing
- but in this case it should not (only) think about a backup with level 'full'. Correct?

Incremental and level savesets are dependent on the previous full to be the base of their index information. What this message tells me is that your actions would delete a full saveset on which subsequent unexpired savesets depend, so NetWorker refuses to do so.

Not sure what the “Browse period equals retention period” is trying to tell you.
