8766.0. "incremental remote copy" by BRSADV::BUGGENHOUT () Mon Feb 10 1997 06:49

Hi

I am trying to solve the following, we have a systemA on site 1 and a 
systemB on site 2. We need to remote mirror or copy the disks of systemA
to systemB. In fact the preference is copy (mirror could be done via LSM
and SCSI extenders) on regular intervals. As there is a lot of data we are
looking for a remote copy (or snapshot) program that can do this incremental.
I saw on the NCR web page a kind of software that can take incremental
snapshots and then bring them over to the other site

Any pointer to something able doing this on Digital UNIX ? Or other ideas ?

Hi

 It sounds like you are trying to create a disaster tolerance solution.

Please see:
   http://www-unix.zk3.dec.com/www/clusters.html

    look under Disaster Tolerance

   after you read the information, contact Steve Horn if you still have
   questions or issues.

hi

the customer talks about 'disaster tolerance' but for the moment the 
existing environment overthere (that we are upgrading/replacing) is such
a DISASTER already (no system mgt, no backup ....) that we have to keep
it simple.
We cannot say we do not want to put it there (then they go elsewhere because
disaster tolerance is such a hot topic but they do not understand anything
about it). If we offer a real disaster tolerance it will be
1. too expensive
2. too complicated (and then DEC has not implemented it in a right way ?!)
3. too .....

There are still a lot of discussions to go but to have a simple start i was
wondering about 'incremental remote copy'

Still info wanted if possible
