Scheduling Data Protection Tasks
18 SnapServer Administrator Guide
For example, to calculate the capacity of a SnapServer 520 with 1 TB total capacity in
its default state, consider both the hardware and software configuration:
• The four 250 GB disk drives each provide 240 GB of formatted capacity.
• 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.
Scheduling Data Protection Tasks
Note
For some SnapServers, additional licenses are required for NetVault,
SnapEDR, and antivirus functionality.
Scheduling backups, 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 click
OK
. When the
configuration link appears, click it 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 117 for detailed information on creating and
using disaster recovery images.
GuardianOS contains built-in support for BakBone Netvault to back up to a local
tape and for SnapEDR to synchronize and back up to and from other SnapServers.
GuardianOS also supports several third-party backup agents. For information on
using these backup methods to help protect your data, see “Backup and Replication
Solutions” on page 147.
