Stage Policy

[nohandleisworking]

Using Networker 7.1.2 on Solaris 8 server.
Can anyone explain some of the different items of the Stage Policy available in "nwadmin" ?
Basically, I want to set up a Stage Policy that will automatically stage oldest savesets from my adv_file device when the adv_file device is 90% full and move it to another pool which is a tape for long term storage.

The following behavior of of these attributes is not totally clear to me (in Detailed view of Stage):
(1) Max Storage Period - some number is required, but I don't really want to use it. Mainly, I want staging triggered when the adv_file device reaches 90% and then will stage until it trims to 60% all the oldest savesets. However it is required to put a number in there, so should I use a really high number?
(2) For "Recover Space Interval", it says in the admin guide that "once a saveset is staged from the selected device, its media db entry is removed, and the space once occupied on the volume can be freed and recovered from Disk." this is fine, however I want to make sure it doesn't also remove the clone copies I have on other tapes. You see, I have some savesets of nsrarchives on the adv_file, which I make daily clones of onto an LTO tape. Will "REcover Space Interval" make Legato stage just the ssid/cloneid of the saveset on the actual adv_file and thereby my existing Clone tape will still be good, or will it Stage remove knowledge of that from NetWorker as well which is not what I need it to do.

thx

(1) Max Storage Peroid
In the UNIX admin GUI this is very easy as the min/max values are stated at both ends of the parameter. For the Staging policy, the min. value is 1 day.
So the "Max Storage Period" is also a "Min Storage Period"

(2)
The staging policy only applies to the (Advanced) File Type devices You have selected - it will not touch any save set on tapes. You can easily verify this as your tape devices will not be listed unde "Devices".

Hi 605,


ok your explanation for number (2) is good and makes sense and I just tested it.

but I still don't understand usage of number (1).
It seems that in Stage policy it's an "or" so if I set "90%" and I have "Max Storage Period" at say "7" days then Legato Stage policy will automatically stage all old savesets when capacity of my adv_file reaches "90%" OR when I have a saveset that is 7 days old which is not what I want.
so I was thinking of getting around it by making the number 356 days or something big.

Your observation is correct. From the nsr_stage manual page:

.... Save sets will be staged ... when the file system is 90% full or 7 days after the date of the backup, whichever comes first. ...

BTW the max value is 1000 days.
