Figure 13 Shadow copies stored on a source volume
The cache file location can be altered to reside on a dedicated volume separate from the volumes
containing files shares. (See Figure 14 (page 42)).
Figure 14 Shadow copies stored on a 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, limits can generally be set higher, or set to No Limit.
See the online help for instructions on altering the cache file location.
CAUTION: If the data on the separate volume L: is lost, the shadow copies cannot be recovered.
