If you must manually sync, MySQL Table Sync is designed for efficient
syncing over a slow network.

It's still not finished, but I use it in production all the time.
If there's any way you can possibly do this via replication, I would
recommend you do that instead.

Thank you very much.
The VPN bandwidth will be 128/256 kbps. Also we have to make updates to both
locations simultaneously and our application is provided with locking
mechanism for updating records and resolving conflicts to update same
record.
Also please give the details about term active/active and how it could be
implemented?
It can be possible to update the data to both servers and keep another for
reporting only purpose.
Is it possible to make HO as Master and Reporting as Slave and Site Server
as another master and same Reporting as Slave. i.e. Reporting will be
the salve for both masters in Replication?
Thanks again

Says who?
But clustering won't help. You are looking for active/active, which
could be accomplished but this would possibly lead to specific conflicts
if people are trying to edit the same record.
You've also failed to mention the speed you are talking about. My home
office is a replication point for our large database at our CO. I do
this over Cable.
You could try active/active, assuming you work out some type of conflict
resolution plan. If each site will generally be editing their own data,
but combined for reporting only, then active/active should be fine, even
if you are talking about 20KB/s.
Can we generate scripts on windows to sync them manually?
Thanks

and
once it catches up on the slave then it will continue to be an easy
sync in
the future as long as both are running. How big is the database you
wish to
synchronize? What connection are both servers on?
Is there anyway possible to disable to VPN between the two D.B.
servers?
Perhaps a firewall in between is in use and you can simply setup
access
rules for both to talk to each other? The VPN tunnel is most likely
a
big
slow down.

Hi,
I have a problem as below-
We have a MySQL server for our ERP database. Now we have to
implement
the
ERP for Head office. HO is away from the current setup and
connection
between the two is through VPN at slow speed. How can we
synchronize the
two
MySQL servers?
Replication,
Cluster, or manually?
Thanks for your replies.
