Enabling Systemwide Secure Snapshots

Use the instructions in Accessing Remote Management to log on to the DXi system.

To enable and schedule snapshots, the system must be configured to use a NTP (Network Time Protocol) server to set system Date and Time. NTP is selected in the Getting Started Wizard when you initially configure the DXi for backup and replication, but can be confirmed or changed using the steps in Date & Time. NTP-set systems allow the consistent and unchangeable network-defined date and time settings for your system.
If you do not have or set your system to use NTP, Secure Snapshots will be disabled for your system.

To confirm or change your DXi T10 system date and time settings to the NTP (Network Time Protocol) server, use the instructions in Date & Time.

Note: As the topic instructions note, changing date and time setting requires a system reboot and can take up to 15 minutes.

Version 4.3 or later is required to enable and use DXi Secure Snapshots. Complete the instructions in Uploading a Software Upgrade File to upgrade your DXi Software version.

Secure snapshots are disabled by default. Complete the following instructions to enable snapshots in your system.

1. From the Configuration > System page, select Secure Snapshots.



Caution: If NTP is not enabled in your DXi T10 system, the Enable Secure Snapshots box will be inactive (grayed) and you cannot enable Secure Snapshots. See 2. Confirm or Change System Settings to Use NTP.

2. Click Apply.

Secure Snapshots are now available for shares, partitions, or OST LSUs in your system where deduplication is enabled.

3. Use the instructions in Enabling Secure Snapshots for Individual Shares to enable snapshots for individual shares, partitions, or OST LSUs.

Note: Once snapshots are created and scheduled in the system, you cannot uncheck the Enable Secure Snapshots box and globally disable all enabled and scheduled snapshot events. Use the instructions in Enable or Disable Snapshots for Individual Shares, Partitions, and LSUs to select and disable secure snapshots.

In the Secure Snapshots Global Configuration screen, enter the number of days from today's date before currently scheduled and existing snapshots can be deleted.
