Figure 9 Shadow copies stored on a separate volum e
The main advantage to storing shadow copies on a separate volume is e ase 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 shad ow copies to be purged too soon, or not created at a ll. By storing shadow copies
on a separate volume space, limits can generally be set higher, or set to No Limit. See the online h elp 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 co pies
Enabling shadow copies on a volume automatically results in several actions:
• Creates a shadow copy 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 weekd ays.
NOTE:
Creating a shadow copy only makes one copy of the volume; it does not create a schedule.
NOTE:
After the first shadow copy i s created, it c annot be relocated. Relocate the cache file
by altering the cache file location under Properties prior to enabling shadow copy. See
“Viewing shadow copy properties”onpage52.
