Remote replication

[chandregowda]

Hi Experts,

I have one production site and DR site.
Both site contains the sun storage with 10 disks.
Only write access to disks allowed from production site.
Storing the data on DR site using Remote replication method,Because only read access is there from DR site.
If primary site goes down,DR site needs to get the write access on disks.
What will be the solution for this situation.

Thanks,
chandra

have you looked at 'rsync' ?

Comes on the companion DVD in Solaris 10, and is installed by default in OpenSolaris.

Just thought I'd add this URL for automated Backup over SSH:

Hi Jad,

Thanks for youe reply.

Your solution more relevant to Backup.

But i need to run the server continuously after primary site fails also.

Thanks

What system is it running?

Oracle has "Standby database" mode ... other databases use similar.

running rsync every 15 minutes might be all you need, unless you need it to be a complete fail over, or load balancing system.

Is this just Data storage, or is there a specific Application that you need up?

Are the machines in the same location?

what kind of failure are you expecting? Disk, Power, Network or Processor Failure?

clustering software, active / standby.

I take it you've looked at:

(sorry forgot to check for a reply for ages.)

Use EMC srdf, does what you need. Or Hitachi truecopy.

Whether or not it's relevent to you I don't know ...

but if you are looking to create a cluster of sorts GlusterFS has recently come to my attention.

http://www.gluster.org/docs/index.php/GlusterFS_Features

It's under a GPLv3 license, but apparently runs on pretty much any system and pretty much any hardware, sposed to allow replication within itself.
