It is better to have a separate system in a separate location as a
backup device. I use a backup server in a different building with a
combination of rsync and glastree as the backup software
infrastructure. All backup jobs are run out of cron nightly. The backup
drives are 4 drives configured as a RAID5 array which is monitored for
drive failure. I keep about 11TB of backup data. I am also backing up
Macs as well as Linux systems with this configuration. It has worked
well for many years.
