retention period between clones and master

[ist69veritas]

Hi,

We're using Networker 6.1 on solaris.
We're using one master pool to back up database weekly and then clone the cartridges.

The retention period is set as 12 months for the master pool, but since we do not want to populate the autochanger with a lot of cartridges, we tried to set the retention period as 3 months on the clone pool. However, we saw that the retention period for the master was reset to 3 months by networker.

My question is : Is it possible to have different retention periods for the master and clone pools for the same saveset?

Thanks all in advance ...

From what I have seen, no. Retention period applies to the ssid, not ssid/cloneid.

Correct - please see the nsrmm man page.

Yup, Legato has yet to make it possible to keep different retention times to same ssid, rather annoying at times.
The workaround is to find the tapes that hold the clones and label them, do not change them to recyclabel in the GUI as that will make the SSID's on the original also recyclabel.
U have to label the tapes to keep the original in the database.

 

[605]

Let me add that you also may change the volume label option to "recycle - manual".
This will prevent NW from relabeling the tape as well.

What I do is I keep my clones on site for 14 days and use a script to delete saveset id's in the clone pool that are older than the 14 day limit. This was the onsite clone is only kept for X days.

# This script is used to free up clone saveset's and volumes
# We will be cloning the world and sending the orginal volumes offsite, Our SLA
# is such that we only will have the most current save sets on site (right now it's 14 days,
# but for the sake of it I am testing with a 30 day on site plan).
# This script will delete any clone from the media database based on the above. It will also

# 2003/06/13 EIS Run nsrim -X two times after saveset delete
