Just wondering what most people with NAS setups do in this regard. On the topic of the 3-2-1 rule (3 copies of data, on 2 different types of media, 1 off-site):

  1. Do you have a second full copy of your data on site, or do you consider RAID with redundancy good enough to satisfy the ‘2’ part of the rule?
  2. Do you back up everything to a cloud service for the ‘3’ part of the rule, and if so who do you use (and why)?

I’m just curious in general what NAS users are doing here, as clearly those with large storage pools (I’m talking tens of TB and up) are going to pay through the nose to have second and third copies.

Cheers :)

    I do 4-1-1.

    Two full external USB external hard drive backups at home (using a multi-drive USB case of course), ping-ponged so that if an accidentally deleted file is also deleted on the most recent backup, I can go to the previous backup.

    A third full external USB external hard drive back-up off-site that gets rotated periodically into the home backups.

    So I don’t believe in “two different types of media”. My opinion is that was coined back in the day when it was assumed tape would be the primary backup. The days of tape for home-sized NAS’s are over, as of 2010 when hard drives briefly became cheaper than even blank tapes. (Then the Thailand monsoon hit in 2011 and the prices spiked, but now prices are comparatively low again).
