Anyone have experience "mirroring" a HDD over a WAN?
We have a scenario where triggers were going to be the "data collection"
and
a "distribution" program to blow extracted data to various end of the
earth.
All this was an attempt to maintain a 24/7 access to a working system.
= All log on to the main server and work as at present.
= When comms break at any branch, they log into their own server and
continue to work (the data being an exact copy of that on the HO
server up until the night before
= synchronization to take place at night, when network traffic is
lowest)
We've now had to abandon triggers, moving to a scenario where we get to
modify source code (not a preferred route). This has caused us to stop
and think... if this can go wrong, how much more the distribution of
data onto every server at every branch (20 branches, plus HO).
An alternative solution is to set up a hardware mirror to handle the
movement of data. A google produces an overwhelming array of choices...
What does the collective authority of the list say?
