Event Description

SyncContrib (Replication / Backup with Unison) at the Toronto Perl Mongers

http://to.pm.org/#052411

Speaker: Martin Cleaver

Title: Using Unison for file synchronization (1 - 1.5 hours)

Synopsis:

Unison is a popular file-synchronization tool for Windows and most flavors of Unix. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas: updates that do not conflict are propagated automatically and conflicting updates are detected and displayed. Unison is also resilient to failure: it is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures.

Martin Cleaver will give an overview of Unison, show it in action (fingers crossed) and outline how he uses it to provide both a backup of a set of files on a TWiki install and two way replica of TWiki from a linux server to his laptop using a plugin he wrote for TWiki, the completely open source and possibly most popular Wiki implementation written in Perl.
