DFS moved back into the realm of possible (for us). Without replication, I don't need as the full amount of storage at each site, enough to support *all* users; I'd really only need enough storage to support the number of users who can physically fit into the site ... (plus some as overflow, of course). > When a user accesses a DFS Namespace, DFS will determine which > member of that namespace to direct the connection to based on the > site they're logging in from. So I would need to make sure all my site info is correct and up-to-date ... So what happens in this case: User at Server_A/Site_A moves to Site_B. I don't know about this move. When the user logs in, DFS tries to map his profile to a server in his site. But there is no server in Site_B with a copy of his files (yet). Does he get an error? Does he just (transparently) connect long-distance back to his files at Site_A? When I do the backup/restore of his files to Site_B, he should Just Work. (He'd have to be logged out while I did the backup/restore, right?) > If you decided to use replication, DFS-R in Windows 2003 has pretty > good compression capabilities, as well as the ability to only > replicate changes to files.
