From the Software RAID HOWTO: --------------------------------------------------------------------------- 2. Why RAID? There can be many good reasons for using RAID. A few are; the ability to combine several physical disks into one larger "virtual" device, performance improvements, and redundancy. It is, however, very important to understand that RAID is not a substitute for good backups. Some RAID levels will make your systems immune to data loss from single-disk failures, but RAID will not allow you to recover from an accidental "rm -rf /". RAID will also not help you preserve your data if the server holding the RAID itself is lost in one way or the other (theft, flooding, earthquake, Martian invasion etc.) RAID will generally allow you to keep systems up and running, in case of common hardware problems (single disk failure). It is not in itself a complete data safety solution. This is very important to realize. --------------------------------------------------------------------------- Source: http://tldp.org/HOWTO/Software-RAID-HOWTO-2.html -- Andreas Micklei IVISTAR Kommunikationssysteme AG Ehrenbergstr. 19 / 10245 Berlin, Germany http://www.ivistar.de Handelsregister: Berlin Charlottenburg HRB 75173 Umsatzsteuer-ID: DE207795030 Vorstand: Dr.-Ing.
