I’ve been using SpiderOak ONE for my online cloud backups since 2012 … almost 12 years. I was grandfathered into an unlimited plan for $125/yr and had just under 5TB backed up to the service. On April 24, the service went down for “scheduled maintenance” to move to a new data center … and was down for two weeks! Worse, there was near-zero communication about the outage, no response to support tickets, affected a lot of people (see here and here for examples), and in fact is still causing problems for customers today (over a month later)!
My annual renewal was coming up at the end of May and this was now the second big service outage so far this year (a total of 20 days of downtime!). It became clear to me that SpiderOak no longer considers their ONE backup service important (in fact, the conspiracy theorist in me thinks they did this on purpose to get rid of ONE customers), so I started looking at alternatives.
