Cloning 1

[ofladung]

Hi everyone,

I would like to reduce the amount of old tapes (1 tapeset instead of 4 per month), so I cloned them to new tapes with more capacity. My question is: is it possible to safely remove the old tapes from our database?

regards,
Oliver

Yes, it is.

However, if you do this, you do not have any redundancy if something happens to the clone tapes.

Be carefull:
if you remove the original saveset, the clone saveset will be removed too. Keep in mind that if you change the original saveset retention, the clone will be affected...

well - if I recycle the old tapes and use them - maybe with a new / different label - what happens to the clones? I don't want to delete my backups - i want to reduce the tapes

As you have your backups on backup and clone media, why don't you just
- stop cloning
- keep the backup tapes
- relabel the clone tapes

This is easier to understand and does not confuse you. But again, you loose redundancy.

I think you're right. I'll send a clone to one of our branch offices for redundancy. Would it be possible to "move" the data from the old tapes to new tapes? We used a HP MSL5030 (200 GB tapes) one year ago, and now we have a HP MSL6030 (two LTO3 drives).
However - thanks for your help )

To move the data, just use nsrstage.

Last question: is it possible to clone a 200 GB tape from a LTO1 drive to a LTO3 drive?

Yes, as cloning is a logical, not a physical copy.
