Figure 17 Shadow copies stored on a separate volume
The main advantage to storing shad ow copies on a separate volume is ease of m ana gement 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, limi ts can generally be set higher, or set to No Limit. S ee 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.
Enabling and creating shadow copies
Enabling shadow copies on a volume automatically results in several actions:
• Creates a shadow co py of the selected volume.
• Sets the maximum storage space for the shadow copies.
• Schedules shadow copies to be made at 7 a.m. and 12 noon on weekdays.
NOTE:
Creating a shadow copy only makes one copy of the volume; it does not create a schedule.
NOTE:
After the firstshadowcopyiscreated,itcannotberelocated. Relocatethecachefile by altering the
cache file lo cation under Properties prior to enabling shadow copy. See "Viewing shadow c opy
properties" on page 58.
