You would need to expand your script by checking with nsradmin first what is the start of the group or what was last start and end time and use that to build range via mminfo.  Some more detailed approach would also include check if that backup was valid or not (eg. was it successful).  With mminfo itself, there is no such thing as last backup parameter as that doesn't translate to any available parameter kept within mdb.

If you have fixed backup intervals, the mminfo command is easy because you can also use smaller time intervals. For example:

  mminfo -q "client=xxx,savetime>-30mins" -r "client,name,level,savetime(25) ...."

There is no single NetWorker command that would list you just the last time a back was done for a certain client:saveset.  The closest example, filtering on group name, will report sorted in reverse chronological order:

     mminfo -avotR -q "savetime>-1 week ago,valid,copies=1,group=(GROUP)" -r "client,name,savetime(20),ssid,cloneid"

To filter based on client:

     mminfo -avotR -q "savetime>-1 week ago,valid,copies=1,client=(CLIENT)" -r "client,name,savetime(20),ssid,cloneid"

You could create a output file, which can then be used massage the data, and clone. The following will create an output file using a semi colon as a delimiter:

     mminfo -avotR -q "savetime>-1 week ago,valid,copies=1,group=(GROUP)" -r "client,name,savetime(20),ssid,cloneid" -xc;  > out.txt 2>&1

I did find the following that uses a Perl script to determine the most recent level=Full backups.  Take a look, and you can modify it to suit your needs.  I did not test it, but at the very least, it looks promising:

Subject: Re: [Networker] List last FULL using mminfo

Here's one that I wrote a few years ago to do this.

#!/usr/bin/perl

use Getopt::Std;

my %opts;

getopts('s:', \%opts);

#$ENV{"LC_TIME"}="LC_TIME=en_GB.ISO8859-15";

$ENV{PATH}="/bin:/usr/bin:/usr/sbin:/opt/networker/bin";

open MMINFO, "mminfo -s $opts{'s'} -q \"!incomplete,level=full\"  -r

\"nsavetime,savetime,client,totalsize(9),name\" |";

while ( ) {

        next if /^  save time /;

        ($nsavetime, $savetime, $client, $size, $mult, @name) = split;

        $name = join " ", @name;

        if (defined $latestnsavetime{$client}{$name}) {

                $l_nsavetime = $latestnsavetime{$client}{$name};

                if ($nsavetime gt $l_nsavetime) {

                        $latestnsavetime{$client}{$name} = $nsavetime;

                        $latestsavetime{$client}{$name} = $savetime;

                        $latestsize{$client}{$name} = "$size $mult";

                }

                else {

                };

        }

        else {

                $latestnsavetime{$client}{$name} = $nsavetime;

                $latestsavetime{$client}{$name} = $savetime;

                $latestsize{$client}{$name} = "$size $mult";

        };

};

for $client (sort keys %latestnsavetime) {

        for $name (sort keys %{ $latestnsavetime{$client} } ) {

                printf "%10s %-15s%-40s%-10s%8s\n",

$latestnsavetime{$client}{$name}, $client, $name,

$latestsavetime{$client}{$name}, $latestsize{$client}{$name};

        };

};

Use the below commands for your requirement :-

mminfo -avot -xc, -r "client,name,ssid,cloneid,volume,totalsize,sscreate(17),sscomp(17),sumflags,group,level,ssbrowse,ssretent,location"

Calculate between the period:-

mminfo -avot -q "savetime>=04/01/2017,savetime<=04/02/2017" -r "client,name,savetime,sscreate,ssid,cloneid,volume,location,ssretent,sumflags,level"

Check save set which was backed up on yesterday only:-

mminfo -avot -xc, -r "client,name,ssid,cloneid,volume,totalsize,sscreate(17),sscomp(17),sumflags,group,level,ssbrowse,ssretent,location" -t yesterday

Checked for particuler client:-

mminfo -s Backup Server Name -r "client,name,savetime,ssid,cloneid,volume,location,ssretent,sumflags,level" -q "client=Client Name,savetime>04/01/2017,savetime<04/02/2017" -ot

Data pulled from last 7 days:-

mminfo -avot -xc, -r "client,name,ssid,cloneid,volume,totalsize,sscreate(17),sscomp(17),sumflags,group,level,ssbrowse,ssretent,location" -t '7 days ago'

-a >>   Causes queries to apply to all complete, browsable save sets, not just those in the last 24 hours.

-v >>   Displays additional verbose report output

-o >>   Sorts the output in the specified order

-t >>   Restricts the reported information to the media  and/or  save  sets  pertaining  to  the  save  sets  created  on  or  after  time.

-xc, >> displays values separated by any single character or string. For example, âmminfo -xc,â will produce comma-separated values.

-r >>   attributes to be displayed for the current  query

> Check save set which was backed up on yesterday only:    -t yesterday

Sorry, but this is incorrect.  Using the parameter "-t yesterday" will find all savesets that were backed up since yesterday, not only yesterday
