Figure 52: Shadow copies stored on separate volume
The main advantage to storing shadow copies on a separate volume is ease of management and
performance. Shadow copies on a source volume must be continually monitored and can
consume space designated for file sharing. Setting the limit too high takes up valuable storage
space. Setting the limit too low can cause shadow copies to be purged too soon, or not created
at all. By storing shadow copies on a separate volume space for Shadow Copies may be
manage separately, limits can generally be set higher, or set to No Limit. See the properties tab
of the shadow copy page for a volume to alter the cache file location, covered later in this
chapter.
Caution: If the data on the separate volume L: is lost, the shadow copies cannot be
recovered.
