advice request: storing images on CD

[bmattock]

I am not overly fond of external encryption other than my working OS. It can be hard to recover if there is a catastrophic failure.

And of course it destroys your NAS' performance, but there are reasons for encryption, but I try to limit it to a few folders, I would not use it for images.

I have always preferred JBOD over NAS.

Sonny Sichtstein's post is the best so far. All OS X users should take note.

The problem with Apple's TimeCapsule is that it backs up the latest information on your computer, erasing the oldest backups when it gets full. I would like to keep photo files stored somewhere other than my devices to free up storage space on my macbook, iPad, and iPhone. TimeCapsule backs up current files. Maybe I'm missing something?

Yes, it does erase the oldest data when the back up drive has no more room for new data. But data you value (i.e. files you have not deleted or modified) are still present. That is, the back ups are incremental so only data that has changed since prior backups is affected.

With regard to photography most of the 1TB on my working HD are image files and LR Catalogs. I started storing digital images (as scans) in 2006. In 2008 I began storing 12 MB raw files. In my case after about two years of photography storage (1TB HD Mac Mini) a 2 TB HD lets me keep about 12 months of new data backed up. Deleted or modified data older than that isn't very useful. Another strategy is to spend $60 for a new HD When Time Machine warns you it's about to old delete data.

However I store all my original raw files on a separate external HD. I think of this as a virtual file cabinet of negative sleeves. I manually back up the raw-file HD to a third HD. So during image selection I delete raw files from my working storage space. The keepers are on three devices and all the originals are on two.

From one backup to the next, how does TimeCapsule deal with a change that is a deletion? (As in a number of photo files that are removed since the last backup.)

Here's something to save up for......

Got the link from one of my students in physical networking last week. Very cool idea hope it's more successful than bubble memory was.
