| Usually /data2 is configured as the mount point of a RAID[1|5] stack, meaning that data in it have a certain level of redundancy which can protect against disk failures. Note however, that storing all of your data on /data2 will not prevent loss if all disks in the array configuration `die' and/or your computer tower gets destroyed by a fire or any other disastrous event. | In most cases, but not always, /data2 is configured as the mount point of a RAID[1|5] stack, meaning that data in it have a certain level of redundancy which can protect against disk failures. Note however, that storing all data on /data2 in RAID configuration will still not prevent data loss if all disks in the array `die', your computer tower gets destroyed by a fire or in any other disastrous event. **You are strongly encourage to keep your personal backup of any important data.** |
