You're right, losing incrementals and file level restore can be a disadvant=
age. I guess it depends what you're using VMWare for.<br>
<br>
I've only seen it used for consolidation of low utilisation development
and test servers. For these systems, nightly "whole system snapshots&q=

are usually sufficient. Maybe you could even give developers access in
VMWare to take snapshots of their virtual server, and restore it, and a
bit of disk space, so they can manage their own day-to-day testing
related backups and restores. <br>
