UPGRADING MY CONTEMPORANEOUS BACKUP:
Two SanDisk 64GB flash drives have arrived, and I am now going to store all my current working files on one of them (about 50 GB total), with Allways Sync mirroring them on the other. When I finish a project, it will only at that time be moved to my hard disk for triple-redundant archiving.
It will be nice to have constant real-time backup of all my current work, rather than just most of it (which was the case when I used a pair of mirrored 32GB flash drives.) In the event of a disaster, I can grab two San Disk sticks and have all my current work. My off-site archives are backed up only once a month.
Of course, I’m still doing nightly backups of current projects to a pair of mirrored 6TB Drobo “RAID-like” arrays. “Trust, but verify” works for silicon, too!
