6022.0. "Restoring SQL Server backups from Intel on Alpha" by MOSDM::GALITSKY (Andrei Galitsky) Wed May 21 1997 04:50

Hi

Are there any hope to restore on Intel machine SQL Server's backup made on Alpha NT.
I know that this was impossible on version 6.0. Will it be possible in the future?

Customer wants to use Intel computer as a backup to AlphaServer - but how it is 
possible to restore SQL's database?

Thanks in advance

You might also ask this question in the SQL Server conference
AMCUCS::MS-SQLSVR  If you still can't restore from a different
architecture backup on SQLServer v6.5, you may be able to
achieve what you want with SQLServer replication. This is described
in detail in Part 6 of the 'SQLServer v6.0 Administrator's
Companion' (included with SQLServer Books Online.) There are
some restrictions on replication, however.

No way to restore backups from Alpha on Intel or vv.
you can setup replication or like (what we did as backup) daily transfer (it
becomes a scheduled task) the database. THe first is contigious the second a
one (complete) shot per time interval you define.

I have to disagree with you here.  We are using SQL Server 6.5 on Windows NT 
Alpha and Seagate's Backup Exec (with SQL Server integration) on an Intel machine 
to do the backups on our entire environment.  We have successfully restored a 
corrupt SQL database from our Seagate backup.

Frankly, I didn't know that this was not supposed to work, but we did not have 
any problems with it.

    I think we have language semantics in play here.
    
    My thought is that a SQL backup of an Intel based SQL database cannot be
    restored to an Alpha based SQL database.
    
    .4 seems to be using the Intel to run a backup utility getting the
    data from an Alpha SQL database.
    
    The issue is not how or where the backup utility is run but what hardware
    architecture did the database originate on.
    
    Please correct me if this is wrong.

Ahhhh...gotcha.  Re-reading, I agree.

.2 does give some hints, but I think the customer probably wants to 
do what we're doing.  Really need more info before making any more 
guesses.
