I don't know much about the windows procedure for backup and recovery….
For backup and recovery, in an ideal Linux environment, rsync is used to synchronize alf_data and mysql dump lets u take a
dump of the alfresco DB. Normally , once the rsync of alf_data is over, then you do the mysql dump, to avoid having a
corrupted repo. This is a hot backup procedure , which means , replication done on a running Alfresco System.
The Distributed File System (DFS) technologies in Windows Server 2003 R2 offer wide area network (WAN)-friendly replication
as well as simplified, fault-tolerant access to geographically dispersed files.
In that context, I presume that DFS should serve the purpose.
