Problem with that is if the mirror breaks then the files on the remote server could be broken at the Universe level.
An update to a Universe file may result in more than one OS level write due to overflow etc. If the mirror broke between these writes then the remote file may be corrupted. At least that's my understanding/experience anyway. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dennis Bartlett Sent: 02 September 2004 14:20 To: [EMAIL PROTECTED] Subject: [U2] Anyone have experience "mirroring" a HDD over a WAN 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? <PRE> --------------------------------------------------------- GWK BEPERK/LIMITED (REG: 1997/022252/06) POSBUS 47 PO BOX 8730 DOUGLAS Direkteure/Directors: NB Jacobs, FJ Lawrence, J v/d S Botes, JH Coetzee, JGD Smit, JF Jacobs, AO M|ller, JW Smit, JP Snyman, JG Stander, JH van Dyk(MD/BD), JG Jacobs, A M|ller, M van Zyl, Sekr/Secr: E van Niekerk.
