28 Tapes...4 Weeks...1 Tape per day... but. 2

[kikithefly]

Well, I am certainly doing something wrong, but as a noob, it is pretty normal ).

I use a HP MSL6030 with 29 slots.
I would like 1 FULL SAVE per day on one tape that should go to the offsite storage.
Next day, i want the system to take another tape...But legato continue appending the tape if i don't take it away...
How can i handle this please ?

Regards

This is NW's behaivour - it tries appends data to a media of the same pool.

What you want can not be done straight. There is no way to force NW to take another tape as long as the current one is available. So to force NW to use another tape, you must remove the current media.

So you may manually eject the tape every day or you write a script which does it for you at the end of the backup.

This may sound pretentious, but I'd suggest you explore Legato Networker a bit further... you may find new and better ways to use your existing hardware as well as your investment in Legato Networker.

Example: If you have more than one tape drive you could have FULL backups go to one set of tapes and offsite backups automatically 'cloned' to a separate set of tapes. (Automatic cloning can be enabled to be run when the save group finishes.) Each day, the clones can be removed and taken offsite - they will then return after a few weeks.

In the above scenario you will have two sets or "pools" of tapes, each pool has tapes that are labeled with that pool name.

Inside the jukebox, the full backup pool tapes remain until they are eligible to be overwritten. This overwrite time is controlled by the browse and retention times set for each of the client systems.

In this way, there is a full backup onsite in the event of the immediate need for a recovery as well as an offsite disaster recovery backup.

Thanks for the info.
Unfortunately, i don't have 2 drives, so i can't clone
But if the budget is ok, i will go on this.

By the way i am searching a way of :
A) Unmount the daily Tape (nsrjb -u ....)
B) Withdraw it to the mail Slot (nsrjb -w....)

But i can't find out how to do Withdraw the tape that was in the drive... as a nsrjb -u -w doesn't work.

There must be a script or something like that being able to perform the unmout + the withdraw of the same tape in one shot ? No ?

This will enable my operator to access only the mail slot, and take out the tape without manipulating the MSL.

Thanks by advance.

Go for the last bootstrap save set - it must be on the tape.

So the script looks like this:
mminfo -q "name=bootstrap, time=1 hour ago" -r volume
nsrjb -u volume
nsrjb -w volume

Usually NW will eject the media after 10 minutes and you do not need an unmount but if you want to start earlier ...

I do it through a VB program. mminfo to get the tapes used last night, then nsrmm -o full on each volume identied, then a call to nsrjb -u (unloads all drives) followed by (as we use an STK silo) stk_eject of the tapes. This latter could be replaced with an nsrjb -w.

So, all you need is to script these in sequence.

Ok thank you everybody.
It works now with a script.
