Testing teamsite store backup

Hi All,

We need to test our iw-store tape back ups to see if the tape back ups are good. We are trying to take a tape back up of our production TS iw-store and restore it on our dev TS server. Here's wat we are planning to do -

1) Get the iw-store tape back up and restore it in our dev TS server.
2) Point the dev store to the restored store temporarily
3) Verify that we have the content in all the branches with version history

The only think i guess we will not be able to verify is the file permissions. I guess we may need to migrate user id/groups also to the dev system to be able to do that. Any thoughts on how to do this? Appreciate if anyone who has done this before provide some tips or pointers on this procedure and comment whether this is the correct way to do this?

Env: TS 5.5.2 SP6/Solaris 8

We are also planning to run iwfsck on this as a first step to our migration to our upgrade to 6.7 - but thats secondary. We are primarily concerned about the validity of the tape back ups.

Thanks

You might consider finding a window-of-opportunity to test this on your PROD server so you don't have to worry about users and groups.

Thank you Fish! I see that you have a very valid point about iwfsck, so we have included this also in to our DR scope.

Since planning any tests on prod server is near to impossible (our CMS has around 600 users worldwide using TS 24 x 7), we are planning to split the tasks between dev and prod server. We plan to restore the tape back up on an nfs mount in our dev server, run iwfsck there to determine the integrity of the store and if everything looks good, point this mount to our prod TS as an additional store to verify the content & permission.

Couple of questions here:

1) I believe TS looks at underying OS for user/groups, so once we add the additional store to prod server (which actually resides on our dev server) will TS be able to assign correct user/grp permission to this?

2) Can iwfsck be used to test the store even without adding it to TS? ie, does it work just on the file system? Also do you know how long does it take to run on a 300 GB store?

Thanks

One thing you should probably look into the next chance you have (before perhaps, but definitely after you upgrade) is the running of iwfsshrink....

[QUOTE=ghoti]

section of /etc/iw.cfg to define additional content store: store_directory_iwstore2=/local/iw-store2 store_comment_iwstore2=backup of production iw-storeStep 5: Reset configurations using the following command: /usr/iw-home/bin/iwresetStep 6: Activate the store using the following command: /usr/iw-home/bin/iwstoreadm -a iwstore2 Step 7: Log in to TeamSite UI and check the content of the new store. Do random checking of the branches, workareas, files and directoriesStep 8: To check workarea permissions, mount /local/iw-store2 of dev server on prod server and repeat steps 4 to 7 on production TeamSite server.

From a casual review - the steps sound about right.
Take careful notes throughout the entire process so that you can make sure that you have the actual process used fully documented upon completion (you never know when you'll need to go through it again)
