Re: Faster comm on a COPY

[rob@xxxxxxxxx]

I believe that you're right, the OS copy would be faster.  However, when 
the users shell out money for a backup iSeries they don't expect a whole 
lot of downtime.

Funny how you can shell out money for a backup iSeries to run email but 
you won't for an iSeries that runs your ERP, payroll, accounting, etc. Big 
part is because clustering comes in Domino, with traditional iSeries ap's 
you need something like Mimix.  That takes some serious $, some training, 
and constant hand holding, just from what I've read.

Rob:

I think that for this type of thing, you should FTP or do an OS level copy 
of
the files from the iSeries to your backup server. The throughput should be
faster. The drawback is that both Domino servers have to be down.
