Backup Best Practices

The following are general recommendations for performing backups. Keep
your company-specific needs and environment in mind when implementing
these suggestions.
The Case for Regular and Reliable Backups
The TaskSmart N2400 appliance has a range of high-availability features,
including:
RAID 5 for the data drives
RAID 1 (mirroring) for the operating system drives
Snapshots
In addition to these features, regularly scheduled backups to removable media
are crucial in safeguarding your data against accidental loss, intentional
tampering, or hardware failures.
It is recommended that you configure data disks in RAID 5 arrays. This
configuration makes data loss due to disk failure unlikely. Two drives in the
same array would have to fail at the same time for data loss to occur.
Nevertheless, it can happen, and backups prevent an inconvenience from
becoming a tragedy.
