Enable the Global TTL Feature
To enable the global TTL feature, run the group command with the
desired units (hours | days | weeks) and the numeric value of units.
NOTE: It is recommended that you select
an expiration unit value higher than any other currently existing schedule
retention to ensure that the snapshots are retained as long as
required.
IMPORTANT: Make sure that the system time on your array is set correctly,
and that if you have configured an NTP server, the server is up to date and
functioning correctly before enabling the TTL feature. Incorrect settings could
cause snapshots to expire sooner than expected.
Enable the Time-To-Live Feature.
