Data backup

I was keeping in mind for a long time that I need to improve my data backup strategy. This topic was recently discussed in one of the internet forums I read; and following that discussion I finally made a move :) I should have done that earlier, but luckily I am not too late because I didn't loose any data yet.

Until now I was backing up my RAW files + edited PSD files on 2 recordable DVDs, both stored at home. Personal non-photography data was occasionally copied on another hard drive on the same PC. Although my personal experience with recordable CDs and DVDs is good I've read many times about CDs/DVDs becoming unreadable after several years. Also saving the data on the same PC (even on a separate hard drive) isn't safe at all.

So my new plan is the following:
* Keep making a copy on DVD, but just one copy. That's for RAW + edited PSD files.
* Make 2 copies on 2 external hard drives (different brands). One of them stored off-site (swapped monthly). RAW + PSD + personal non-photography data.
* Keep a copy of most important data in online storage - I've chosen Amazon S3 for reasonable price and good SLA. To keep costs low this will only be used for selected most important RAW files and selected personal data.
