Changing an existing storage policy

[myuserid7]

I have a Storage Policy with one Primary copy, which writes to tape.

I would like to modify this SP so that it writes to disk(magnetic media) and a syncronous copy that writes to tape.

I'm concerned as to what will happen to all the previous back jobs if I modify this storage policy. Do the previous jobs become invalid/inaccessible if an existing SP is modified ?

Thanks.

Best just to create a new SP and point your clients to it.

Thanks,
What happens to all the backups that were done by the previous SP ?

If the client are pointing to a new SP. will I still be able to access and restore from the old SP ?

thanks.

Yes, you will still be able to access the old backups until the retention is over...just don't delete the old SP or else the pointers will be erased and you would need to use explorer to restore.

Good practice for SP's that you aren't using but, are saving is to rename the SP so that it starts with something like zzz or something which then moves it to the bottom of the SP list and out of the way.

Once all backups tied to that SP are out of their retention time then you would be able to delete it.

Thanks for you quick response.
I wasn't quite sure how CV handled SP etc.

But as you say, as long as I dont delete the old SP the pointer should be there to the backed up data.

Thanks a lot.
cheers

Hi,

It's easier to create a new copy in the existing policy. This new copy can point to magnetic disk, and be selected as a primary copy. You don't have to change your clients.

Next backup will go to disk and you will be able to create auxiliary copies of your new backups to tape.

Its important to remember that once you re-associated your subclients to a new Storage Policy copy that the remaing jobs will only honor "days" retention.

Example: if you are using: 1day 15cycles when you move the subclient you will only retain 1day.
