Backing Up and Restoring Files
Disk Checkpoints
5-8
Note When checkpoints are created, they do not use much disk space. As you
make changes to the disk volume, checkpoints use increasing amounts of
space. Checkpoints may be deleted automatically if the system begins to
run out of disk space. To save disk space, delete old checkpoints
periodically.
Checkpoints appear as a directory in the virtual volume. For example, if
you have two checkpoints for volume X (one you created named
ABC
and
a scheduled checkpoint named
20000119-090001,6h)
, you would
find the following on the virtual volume:
/X.chkpnt/ABC (your checkpoint)
/X.chkpnt/20000119-090001,6h (scheduled checkpoint)
Checkpoints have benefits and limitations.
