not really...you will need to shrink it if it gets too big.  BUT, if you do frequent enough log backups, you shoudln't run into any problems.

from your responce,  can i assume sql server 2005 or 2008 do not compress? or compression in 2008 is no superior than 2005?
say the database size would grow to 1 TB and i'm planning on backingup the log every 3-4 hours.

also, you mentioned to shrink the log, i guess this comes as an option in SSMS, is it?

you can right click on the db and go to tasks and shrink it from there.

I don't think log compressions is an option in 2008...data compression is, but log compression...it is ssequential data...really nothing to compress.

If you plan on your log file getting big, do more frequent log backups.

Also, read this article I wrote about it.

Log compression is supported in SQL Server 2008 Enterprise but not in 2005.

just to be clear, David you're referring to compressing the log backups, and not the log files themselves, right?

Yes. For log shipping it's the size of the backup that matters. You don't need to do anything with the files.

ah...sorry, thought you meant the log itself. Sure, you can compress both backup types, but with Enterprise Edition in 2008 only.

Yep..but unless I just missed it, I didn't see where the author has referred to using log shipping.

I read "before shipping" and assumed that's what he meant.
