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 ? regina

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 regina | |||||
| 8766.3 | rdist does this | SMURF::DUSTIN | Mon Feb 10 1997 12:06 | 4 | |
Have you looked at using the rdist command?
