You need both raid and a backup, and IMO it is more important the backup. If you make a goof and delete something, the data will be deleted on all the disks of the array. If you have a good backup strategy, you can recover deleted files. It is as simple as that. All that you do is done to the entire raid array. Any bad thing happens to the array - you are protected only from one type of failure: a disk failure. Note that with rsync you can have a history of changes: the new directory has the new files, and hardlinks to the old files that exist in the previous directory. But doing backups every 15 minutes is excessive wear. You would need a third disk with daily backups, and powered off the rest of the day. - -- Cheers / Saludos, Carlos E. R.
