I came across this link recently that I thought I would share.   It is an article and following interesting discussion about archival optical media – ie. DVD/CD’s and how it is worth paying close attention to the type you buy, the manufacturer, and even the format.   With all the DVD formats out there, I didn’t know that DVD+R is an inherently more stable format than the others.

I don’t use optical media for backup anymore, but do still have quite a few slide scans stored on gold MAM-A CD’s that I need to migrate over to my network drives.   They just aren’t practical when trying to backup large file – you end up with hundreds of disks.  Just think about the chore to have to restore from all of those!   But a lot of people still do use them if it suits their workflow.   Sometimes it is a good idea to have backups in a variety of forms…uber-redundancy can’t be that bad.
