Daily Replication Schedule Example The daily Replication schedule example in this topic illustrates the process for setting up a replication schedule that uses a 24-hour clock (the time keeping convention where time of day is defined on a 24-hour basis). You set or view a Replication schedule in the Replication Schedule page. For more information, see Creating a Replication Schedule. NOTE: Replication schedules can only be set on individual replication-enabled source containers. To set a daily replication schedule that starts at 16:00 hours (which is 4:00 PM in a 12-hour clock format) and stops at 23:00 hours (which is 11:00 PM in a 12-hour clock format) on Mondays, click Edit Schedule (if modifying an existing schedule) or Schedule (if creating a new schedule): • Select 16 in the hours pull-down list and 00 in the minutes pull-down list to set a Start Time of 16:00 on Monday. • Select 23 in the hours pull-down list and 00 in the minutes pull-down list to set a Stop Time of 23:00 for Monday. • Set the Start Time and Stop Time setpoints for any remaining days of the week on which you want to schedule replication. NOTE: You must set a corresponding Stop Time for every Start Time in each Replication schedule you set. The DR Series system will not support any Replication schedule that does not contain a Start Time/Stop Time pair of setpoints (daily or weekly). Weekly Replication Schedule Example The following example shows how to set up a weekly Replication schedule with a start time at 01:00 am on Saturday and a stop time at 01:00 am on Sunday. The DR Series system uses the 24-hour clock convention for its time keeping in which each day is divided into twenty-four 1-hour segments. NOTE: Replication schedules can only be set on individual replication-enabled source containers that you select from the Container drop-down list. • Select 01 in the hours pull-down list and 00 in the minutes pull-down list to set a Start Time of 01:00 for Saturday. • Select 01 in the hours pull-down list and 00 in the minutes pull-down list to set a Stop Time of 01:00 for Sunday NOTE: You need to click Set Schedule for the DR Series system to accept your Replication schedule. For more information on Replication schedules, see Creating a Replication Schedule. Managing Encryption Operations This topic describes using the DR Series system to manage encryption settings and operations. Encryption operations include tasks, such as enabling or turning off encryption, setting or changing the passphrase, and setting the encryption mode. For more information about recommended guidelines for setting up encryption, see the topic, Configuring and Using Encryption at Rest. Setting or Changing the Passphrase A passphrase is a very important part of the encryption process on the DR Series system as the passphrase is used to encrypt the content encryption key or keys. It is mandatory to define a passphrase to enable encryption. If the passphrase is compromised or lost, the administrator should change it immediately so that the content encryption keys do not become vulnerable. To set or change the encryption passphrase, complete the following steps: 1. Select Storage → Encryption. 74

Daily Replication Schedule Example
The daily Replication schedule example in this topic illustrates the process for setting up a replication schedule that
uses a 24-hour clock (the time keeping convention where time of day is defined on a 24–hour basis). You set or view a
Replication schedule in the
Replication Schedule
page. For more information, see
Creating a Replication Schedule
.
NOTE:
Replication schedules can only be set on individual replication-enabled source containers.
To set a daily replication schedule that starts at 16:00 hours (which is 4:00 PM in a 12–hour clock format) and stops at
23:00 hours (which is 11:00 PM in a 12–hour clock format) on Mondays, click
Edit Schedule
(if modifying an existing
schedule) or
Schedule
(if creating a new schedule):
•
Select 16 in the hours pull-down list and 00 in the minutes pull-down list to set a
Start Time
of 16:00 on Monday.
•
Select 23 in the hours pull-down list and 00 in the minutes pull-down list to set a
Stop Time
of 23:00 for Monday.
•
Set the
Start Time
and
Stop Time
setpoints for any remaining days of the week on which you want to schedule
replication.
NOTE:
You must set a corresponding
Stop Time
for every
Start Time
in each Replication schedule you set. The DR
Series system will not support any Replication schedule that does not contain a
Start Time/Stop Time
pair of
setpoints (daily or weekly).
Weekly Replication Schedule Example
The following example shows how to set up a weekly Replication schedule with a start time at 01:00 am on Saturday and
a stop time at 01:00 am on Sunday. The DR Series system uses the 24-hour clock convention for its time keeping in which
each day is divided into twenty-four 1-hour segments.
NOTE:
Replication schedules can only be set on individual replication-enabled source containers that you select
from the
Container
drop-down list.
•
Select 01 in the hours pull-down list and 00 in the minutes pull-down list to set a Start Time of 01:00 for Saturday.
•
Select 01 in the hours pull-down list and 00 in the minutes pull-down list to set a Stop Time of 01:00 for Sunday
NOTE:
You need to click
Set Schedule
for the DR Series system to accept your Replication schedule.

Managing Encryption Operations
This topic describes using the DR Series system to manage encryption settings and operations. Encryption operations
include tasks, such as enabling or turning off encryption, setting or changing the passphrase, and setting the encryption
mode. For more information about recommended guidelines for setting up encryption, see the topic, Configuring and
Using Encryption at Rest.
Setting or Changing the Passphrase
A passphrase is a very important part of the encryption process on the DR Series system as the passphrase is used to
encrypt the content encryption key or keys. It is mandatory to define a passphrase to enable encryption. If the
passphrase is compromised or lost, the administrator should change it immediately so that the content encryption keys
do not become vulnerable.
To set or change the encryption passphrase, complete the following steps:
1.
Select
Storage
→
Encryption
