Infinite Log Shipping Chain? What about storing .trn files?

$

Hi,

any thoughts on the length of the log shipping chain . . . or, how many .trn files do you store?

So, On Sunday I do the full backup and restore to the DR box.  Then I kick off Log Shipping every 15 minutes . . . or even every minute (and why not?).  I accumulate (let's say) 10080 .trn files over the course of the week.  

What if I never re-seeded my DR box?

Should I ever bother storing any .trn files after a successful restore to DR?  What would be the point?  I cannot store an infinite number, so the chain is going to get broken atsome point . . . at which time no .trn files are of any use.

So, this question breaks down into two halves:

1.  Periodic re-seed (say, once a week) or not?  Obviously in this case I'd store all the .trns from the initial full restore onwards.  If I choose to do a periodic re-seed . . . then exactlywhy would I do that?  If not, why would I do that?

2. If I choose not, then what would be the value of storing any .trn files at all?

Your thoughts would be most appreciated.

A Merry Christmas and a Happy New Year to all our readers!
