Best Replication Type please

Hello,
We are implementing a high availablity solution to our SQL
Servers, so if our production server goes down we have a
standby server ready to go.
So we would like to know the best type of replication,
bascially we want to update the stand-by server every 5
minutes. We cannot use the log shipping as we backup the
transaction log every 10 minutes.
Personally I think we should be using snapshot
replication, does anyone have any major disagreements with
this ?
Thanks
PeterSnapshot replication would give you a complete copy of the publication ....
Probably some sort of incremental thing might be better... perhaps
transactional...
But be aware-- replication does NOT replicate system tables, so
permissions, etc will not be replicated..
Also, SQL Replication is not very friendly about Schema changes ,
adding/dropping columns, or changing data types...
For these reasons, may people use log shipping.

I would love to use Log Shipping, but I'm assuming that it
produces the same internal result to the log file as a log
file backup, if that the case then the backup we have in
place will not work. This is somewhat of a 'legacy'
backup, and one I have been specifically told not to touch.
Again thanks for help and I will look into what you have
said.

hen transactional with queued updating subscribers may be used in this situa
tion. Snapshot could be used but this depends on the size of your system - c
reating and sending over bc
p files of your complete database every 5 mins might not be acceptable. By d
efault, standard transactional will not take defaults and identity columns (
although the schema can be scripted), so it's easier to use the queued updat
ing subscribers option whic
h also gives the ability to send back to the publisher any changes subsequen
tly made to the subscriber, if the publisher becomes online in the future.
