Not in the slightest. I&#x27;d rather have some redundancy up front than try to restore a bunch of junk from backups.<p>Backups are important, but not ever having to use them is even better.<p>Not only that, but having RAID or mirror sets gives you flexibility in ways that you might not think about up front. For instance, I just replaced some old 750GB disks with new 5TB disks. I added the new 5TBs to the the mirror set and let it bring all the data across automatically. When it was done, I dropped the 750s out and resized the raid set to use the whole 5TB (I told it it was already clean so it didn&#x27;t have to sync up a bunch of unused space). Then, finally, I resized the filesystem that was mounted on that mirror set. This was all done live, with data actively being read and written to while all this volume manipulation stuff was happening.<p><i>That</i> is why you use RAID at home (and lvm, too).
