16 Snap Server Administrator Guide
• 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 e 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
. For more information, see “Data Migration”
on page 50.
