NDMP Cloning - Multiple Savesets
I use the following command to clone my savesets from our Isilon to tape:
nsrndmp_clone -b "Isilon Clone" -v -S 1370144598/1437250362
This works fine for large savesets, but I have some filesystems that I had to backup individual directories due to either size or other issues. Some of these are as small as 300GB. The issue is that I'm constantly having to send these small clone jobs and overnight, if it finishes, there is a gap in the cloning process. I would like to stack these smaller savesets, so that when one finishes, the next one starts. I tried to use the command:
nsrndmp_clone -b "Isilon Clone" -v -S -t 7/18/15 16:14:00' -e 7/20/15 17:31:00 \ -g IsilonNDMP
This starts to work, but ends with "There was an error checking the saveset list"
Even if I change to parameters to a few hours, I get the same error.
Does anyone that is cloning from a command line have a way to stack these jobs? Batch file or script? It takes me 3 or more weeks to clone a set of full backups to go offsite.
Thanks in advance..

You can use a script but it is not really necessary. In general, it is always a 2-step process:
1. Query mminfo to report the save set IDs. In your case it would be a command like
mminfo -q "savetime>'7/18/15 16:14:00',savetime<'7/20/15 17:31:00'" -r "ssid" > ssids.txt
2. Run the clone process
nsrndmp_clone -b "Isilon Clone" -f ssids.txt
Please read the Command Reference Guide for details and make the necessary changes.

I use the GUI to config CLONE job starting NW 8. However, you cannot control which saveset clone first.

I know nsrstage can handle a space delimited list of savesets. did you try just doing 2 savesets with your first command? The Command reference guide doesn't really say for either, but I know I could do 20 or so at a shot with nsrstage.

Bingo - I'm going to try the script as soon as I get a window - the latest clone has been running for 4 days.
I ran the command and the text file was created. I'm hoping this will work.
ayeung - I can not use the GUI, since this is NDMP.
david - I have not heard of nsrstage, I will do some research.
Thanks.

NSRSTAGE lets you move clones or savesets from one storage location to another. It works similar to nsrclone, and nsrndmp_clone.
It's possible nsrndmp clone will allow multiple savesets was my only thought. I'll agree though, NDMP doesn't work well with Netwoker's GUI clone. It might however work with the clone dialogue in the group. Or are you looking for create a second clone someplace?

I just tried the nsrndmp_clone -b "Isilon Clone" -f ssids.tx, and I get the following error:
C:\Windows\system32>nsrndmp_clone -b "Isilon Clone" -f ssids.txt
08/04/15 10:14:32.770729 ERROR: Failed to build/verify following ssid(s) to continue cloning due to 'volume 1269482611 does not exist

Syntax issue here possibly...
Try to clone just one SSID and if that works for you then it is the script syntax reading a SSID name as a volume name... Check the format of file 'ssids.txt'
nsrndmp_clone -p -b 'poolname' -S XXXXXX
Then try a file with just 2 SSIDs in it to see if same error or other...It might need to be a line by line list vertically rather than other...

So it ends up that it was a syntax error. The correct command is:
nsrndmp_clone -b "Isilon Clone" -S -f ssids.txt
To get the ssids and clone ids to the txt file:
mminfo -q'savetime<=this year' -r ssid,cloneid
I manually add the ssid and clone id to the txt file, in order to choose the savesets that I want to clone.

Sorry, this is not related to your topic, but I am trying to find benchmark numbers on performance for NDMP Isilon backup traffic. How is your performance and are there any benchmarks? Thanks

I'm going to start a new conversation for this one.
