How to use cumulative Snapshot copy values

If you want the amount of disk space consumed by all Snapshot copies not to exceed a certain percentage of the used disk space, you can use the cumulative values in the snap list command output to determine which Snapshot copies to delete.

For example, if you do not want more than 5 percent of used disk space to be spent by Snapshot copies, you can delete all Snapshot copies listed below nightly.1 in the snap list output; that is, nightly.2, nightly.3, and nightly.4. After deleting the Snapshot copies, nightly.1 and all the other more recent Snapshot copies consume 5 percent of the used disk space.
