Anyone using using optical disc media for offsite backups or long term archiving? How is that working out?
Really bigtom dvd... I thought we finished using that type of media for many years ago. For long term archiving I use a slow Magnetic drive where I only store backup files once per month. Each backup is also zipped so that the size is reduced.
So you take one tape/month and store it in a secure location off site. Decent tape drives are expensive. Even the smaller tapes are expensive. I realize that that tapes can write faster than BD-R, but quality media is still only around $2/disk.
A benefit of LTO seems to be bit write error vs block write error. Maybe writing two discs reduces this probability of a write error by half?
In a case where weekly long term isolated snapshot backups of data are needed what is the best medium? Looking for less than 10GB of reliable decade long storage media.
You will get the longest archival life with magneto optical disks (30 years). They are being used in hospitals and government facilities where reliability is a priority.
I recently bought a Fujitsu Dynamo 2300U2 USB drive on Ebay for less than $200 which offers very good write speeds and works with 2.3GB magneto optical disks. They have the same form factor as 3.5 Floppies but are indestructible.
Hmm, a larger sized MD. A bit expensive. Quality Blue Ray is good for 30+ years stored properly.
Actually the MiniDisc is based on the same technology but they came much later to the market. Work on magneto optical data storage began in the 1950s and '60s at IBM and 3M. Steve Jobs used a 5.25-inch MO drive in the NeXT workstation in the 1980s. So we are not talking theoretical lifespan. They have actually been battle tested for over 30 years and can be rewritten millions of times.
Blue Ray discs have a theoretical lifespan of 30-200 years. However, I assume that estimate is for commercially produced Blue Ray discs (Hollywood movies). They use the same recording/manufacturing method as DVD-Rs and commercially produced DVDs greatly outlast home made DVD-Rs. They are manufactured with a stamping method rather than being burned.
