I would like to comment on off-site backups. Back in the 1970's I was an IT manager and I set up a backup and recovery system for the company I worked for. Initially I set up the off-site backup as is recommended in this article. The latest backup was shipped to an off-site location in a city which was 90 miles away by company courier over night. The most recent on-site backup was the -1 generation which was brought back by the courier before 8:00 am.
This system had a big problem on the recovery side. When we needed to recover a file we either had to send somebody on a 180 mile round trip to get the backup or else restore the -1 backup and rerun everything necessary to bring the recovered file up to date.
After a couple of long delays caused by long recovery times from production failures I modified the system. We duplicated the various backup jobs and sent one current backup off-site and kept one on site. That modification worked significantly better than the original backup and recovery system design.
