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.
