Mirroring keeps your server alive when a disk fails.
Backups keep your company alive in case of a disaster.
With backups you can recover from logical errors, maybe a user deleting a business critical file - mirroring cant help you here.
Business critical servers need both: service continuity (mirroring) in case of a disk failure and business continuity (backup) in case you lose the entire server.

check_backuppc
check_backuppc(8) System Manager's Manual check_backuppc(8)
NAME
check_backuppc - A Nagios plugin to monitor BackupPC
SYNOPSIS
check_backuppc [options]
DESCRIPTION
check_backuppc is a nagios plugin that reports on the status of BackupPC. By default, it monitors both archive and backup hosts for
errors.
OPTIONS
-a, --archive-only
Only check the status of archive hosts.
-b, --backup-only
Only check the status of non-archive hosts.
-s, --status-only
Only check the status of the backups, omit connection failures that are less than $Conf{FullPeriod} old.
-H, --hostname hostname
Only check the specified host. Uses hostnames that BackupPC is configured to use, can be specified multiple times.
-x, --exclude hostname
Do not check the specified host. Uses hostnames that BackupPC is configured to use, can be specified multiple times.
-w, --warning age
The days old at which a failure is considered a warning, default 1.
-c, --critical age
The days old at which a failure is considered critical, default 8.
-r, --reduce count
The maximum number of failed hosts for which to reduce reported severity, default 0.
-h, --help
Show summary of options.
NOTES
This plugin must be run on the same host and as the same user as BackupPC. An archive host only takes on a reported type of archive after
its first archive run.
EXAMPLES
/usr/local/lib/nagios/plugins/check_backuppc -r1 -w3 -c8 -b -x otter
Check the status of all backup hosts except "otter". Warn if a failed backup is older than three days old, return critical if a
failure is older than eight days old unless there is only a single failure. In that case, warn if the single failed backup is older
than eight days.
