ie. no single drive backup system is reliable.

Uwe Steinmuller has written about DROBO a non RAID backup device which looks interesting but in reality a single lightning strike within blocks of your house could destroy your computer, your hard drives and your RAID or DROBO so an off site backup is also necessary and has to be updated on a regular basis - in the end, no system is perfect but the question you have to ask yourself is how much data can I afford to lose, not whether you can afford it. Sooner or later you will lose drives, popssibly entire devices and in rare cases entire systems located in a single building.

I have a good system for backup including unplugged external drives (I risk drive failure but not power surges) and offsite (protecting me against fire). What I don't do is do it often enough. Time to invest in reliable backup - including either a raid system or something like DROBO. I look forward to Uwe's articles on backup as they appear at OutbackPhoto in the next few weeks

This is the backup system I use.
Raid (C drive)
One backup connected always
Another only connected to perform backup
Another in a safety deposit box.

This weekend I bought another method of backup.
A 40” x 54 “ - 5 drawer metal filing cabinet (boy is this huge) as I will print as large as visually practical (to retain all detail) and store them in the cabinmet. So unless I have a fire or flood higher then second story I should have images for hundreds of years? With no digital conversion problems. I can’t remember where I read this, but this was mentioned as a great archival storage device.
