Problems rebuilding CFI of expired savesets
July 10, 2018 01:59PM
I know I'm doing something basic wrong, but it's been so long since I had
to do this.

I need to restore from a saveset that had expired and the browse time
expired. So first I did a mminfo, found the SSID/CLONEID I needed for the
saveset and the index of the saveset.
(meaning it was still in the database)
I then extended the expiration by using the nsrmm -S ssid/cloneid -e
12/31/2025, on both the data saveset and the index saveset. Then I marked
them as notrecyclable using "-o notrecyclable".
I used the index from the following day (i.e., I want to restore a saveset
from 7PM on 02/23/2018, so I modified the index taken the next day
02/24/2018).

Then I did a nsrck -L7 -t 02/24/218 <client>. That worked. But when I
tried to extend the browse time, it failed.

D:\>mminfo -q ssid=1267910095 -r name,ssbrowse(22),ssretent(22),ssflags

name browse time retention time
ssflags
index:mjrsfil001 3/27/2018 11:59:59 PM 12/31/2025 12:00:00
AM vrF

C:\Users\admin>nsrmm -S 1267910095 -w 07/11/2018
Cannot exceed the browse time of a recoverable save set 1267910095

So what am I doing wrong here? I missed a step, clearly, but what? I can
(and did) extend the browse time of the actual data saveset I want. But
why can't I extend the browse time of the index?

Thanks. Sorry for the newb question, but I'm just drawing a blank here.

Yes, this is exactly what I did, for both the saveset of the files I
wanted to restore, and the CFI of all clients for that day (the "savegroup
-O"). And it worked correctly for the saveset that I needed to restore,
but not the index saveset. What I don't understand is why it worked for
the saveset of user files, but didn't work for the saveset of the index.

I would have sworn that I *had* done that in the past (extend browse time
of the index). Perhaps I am just misremembering.

Hi Michael,

these are the facts

1. You cannot extend the browse time of a 'recoverable' save set.
At this time the file index data is already gone. Consequently, there is nothing any longer which can be extended.
First you have to modify the browse date of your save set
Then you must run 'scanner -i' to repoulate the CFI info.

2. Even the 'scanner' method will not work in your case.
As CFI backups are 'database' backups, you will most likely not recover a single file. Such does not make sense.
Consequently, NW starts the backup of the CFI save sets with the status 'recoverable'. (since NW 6.0?)
It does not only set the status aprropriately - NW does not even embed the CFI info in the save stream itself.
So it is logically that there is no data which can be scanned at all:

"You can only recover what has been backed up!"
