Have you ever wished you could replicate non database files on your servers?

By Andrew Pollack on 08/01/2007 at 09:52 PM EDT

I've been using a tool called "unison" to keep the files on a pair of linux servers in synchronization. Its available for Windows as well though. This is a command line utility that works very much like Domino replication. A hash database is used and compared rather than a simple look at file dates and names, so renames, deletes, changes, and new files are all replicated effectively.

I'm using it at the file system level to keep not just the files in the domino/html directory in sync, but also several other directories on my linux machine including my /etc/asterisk files. This allows me to have a very up to date failover solution that includes not just Domino but also the PBX, echo server, and all the other things those machines do. Its really helpful for moving things from test into production as well.

For more information, Linux Journal has a good technical article on it.

What we know is that a user's authorizations will be respected through the node.js application to the Domino server -- including reader names, ACLs, Roles, and so on. The way ......
