Jack reviewed strategies for backing up your photo library and the Lightroom catalog, both locally & online. He stressed the importance of having offline storage in case of a catastrophic event (ie fire, flood), as well as local backup for convenience in retrieving lost or accidentally changed/deleted files.

At the end of the meeting, Tina showed us how she makes photo collages using Photoshop.

At the time I said what was important to me was a reliable, easy-to-use approach, at a reasonable cost, and that (very importantly) allowed me to have my backup somewhere other than in my house. 

Since that time I have run across several very useful sources of information that expand on this important topic. 

1. This web page describes 8 different cloud services. The prices vary and available storage does as well. Interestingly the one they recommend is Dropbox! One problem I have is finding a service that is reasonable in price and that will take on storage up to 10 TB.

2. This website discusses “How to Backup Your Computer.” As the title suggests, it is about overall backup, not necessarily photo backup. The site clearly discusses the various ways of backing up and has a useful guide to using Apple’s Time Capsule approach, for example. (It is linked from the Backblaze website.)

3. The Backblaze website. At least one KIPC member uses this and has been very satisfied. This on looks to be affordable and will give me the storage I need.

4. The Carbonite website. At least two KIPC members use this site for backup and are satisfied.
