Scheduling Data Protection Tasks • The four disks when joined in a RAID 5 configuration net 720 GB of capacity for the RAID. • The snapshot space is 20% of the space available on the RAID, reducing the space on the RAID for the data volume by 144 GB. This results in a data volume capacity of 576 GB for this Snap Server 520/1 TB. On a Snap Server 18000, all eight drives are incorporated into the default RAID 5. Scheduling Data Protection Tasks Note For some Snap Servers, additional licenses are required for snapshot and antivirus functionality. Scheduling snapshots and antivirus scans, and creating a disaster recovery image preserves your server configuration and protects your data from loss or corruption. Snapshots can be taken to provide a point-in-time image of files and changes to files to help in quickly recovering from accidental deletion or modification, or to facilitate performing an offline tape backup of an active data partition. Navigate to Storage > Snapshots in the browser-based Administration Tool to schedule snapshots or modify the space available for storing snapshots. Snapshots should be taken when the system is idle or under low data traffic. Set up antivirus protection by clicking the SnapExtensions icon, and then clicking CA Antivirus. Click the checkbox to enable antivirus, and then click OK. The browser will take you back to the SnapExtensions screen. Click CA Antivirus and click the configuration link to launch the eTrust administration user interface for configuration and scheduling of virus scans and virus signature file updates. Create a disaster recovery image (DRImage) on the Maintenance > Disaster Recovery page. This DRImage should be created after the server configuration is complete, and can be used to recover the server or a replacement server to the configured state. See "Disaster Recovery" on page 101 for detailed information on creating and using disaster recovery images.

Scheduling Data Protection Tasks

Note

For some Snap Servers, additional licenses are required for snapshot and

antivirus functionality.

Scheduling snapshots and antivirus scans, and creating a disaster recovery image

preserves your server configuration and protects your data from loss or corruption.

Snapshots can be taken to provide a point-in-time image of files and changes to files

to help in quickly recovering from accidental deletion or modification, or to

facilitate performing an offline tape backup of an active data partition.

Navigate to

Storage > Snapshots

in the browser-based Administration Tool to

schedule snapshots or modify the space available for storing snapshots. Snapshots

should be taken when the system is idle or under low data traffic.

Set up antivirus protection by clicking the

SnapExtensions

icon, and then clicking

CA Antivirus.

Click the checkbox to enable antivirus, and

then click

OK.

The

browser will take you back to the SnapExtensions screen. Click

CA Antivirus

and

click the configuration link to launch the

Trust administration user interface for

configuration and scheduling of virus scans and virus signature file updates.

Create a disaster recovery image (DRImage) on the

Maintenance > Disaster

Recovery

page. This DRImage should be created after the server configuration is

complete, and can be used to recover the server or a replacement server to the

configured state. See

“Disaster Recovery” on page 101 for detailed information on

creating and using disaster recovery images.

Migrating Data from Legacy Servers to the Snap Server

The Data Migration utility can be used to copy or move data from any computer

supporting CIFS/SMB or NFS directly to a Snap Server. Access the utility by

selecting

Maintenance >

Data Migration
