My photography archive is approximately 100GB in size. I keep it safe in the following way:
- Primary datastore lives on PC.
- Sync primary datastore to second HDD internal to PC whenever changes are made. I use Beyond Compare for this.
- Sync primary datastore to external HDD whenever changes are made. Beyond Compare again.
- Burn to blu-ray once I hit my bucket size of ~24GB
- Backblaze online backup for offsite disaster recovery. Costs $5/month or less if you sign up for a year.
1. If you care at all about keeping the fruits of your photography labours safe, I cannot recommend highly enough Peter Krogh's "Digital Asset Management for Photographers, 2e". The bucket concept is from there. See http://www.thedambook.com/
"As a part of this suit, we are requesting a permanent injunction to remove all of their filer products from the marketplace, and are examining the original NFS license — on which Network Appliance was started. In addition to seeking the removal of their products from the marketplace, we will be going after sizable monetary damages. And I am committing that Sun will donate half of those proceeds to the leading institutions promoting free software and patent reform".
Schwartz goes on to outline NetApp's demands in order for its existing patent infringement case against Sun to be dropped:"...unfree ZFS, to retract it from the free software community" and "to limit ZFS's allowable field of use to computers — and to forbid its use in storage devices.""
I've been spending a bit of time writing the memory tester for my Sinclair Spectrum Diagnostics board. The board itself, to recap, contains a flash ROM, a little bit of glue logic, a couple of flip flops and eight LEDs - the idea being that the code running in ROM can display the results on the LEDs, so as to use as little of the (possibly suspect) Spectrum's hardware.
