Notes on In-House/Cloud Backup Solutions Across All Popular OS'es I Researched
View insurance.md

Since it was a lot of work to figure all this out i figured i'd let others know: So I have an assortment of machines on various OS'es now at home, macs, windows, linux. I needed a way to (ideally) back everything up the same way. Also, Apple's Time Machine, as easy as it is to use, was starting to piss me off, at least over a network (taking forever, causing the computer to lag terribly, often saying it had to rebuild the entire backup from scratch, that sort of thing... It always worked fine to a local disk, but I wanted reliable network backup) I decided early on to stick to using S3 protocol to a FreeNAS Mini I already own since pretty much all the backup software I was evaluating was able to speak S3, from all the OS'es. This would also make it easy to switch to actual cloud down the line if that made sense. S3 support provided by Minio http://www.min.io/ was recently added to my FreeNAS and it turns out, Minio is also easily installable on OS X (via Homebrew) and Linux, which meant that I could use my Ma

# I had some issues with this and finally culled together instructions from various sites which finally worked
# The first thing you should do is clone your Phoenix/Elixir repo from Github to a blank Ubuntu c9.io VM
# The next thing we have to do is remove the stock Erlang which is erlang-base-hipe and not esl-erlang
# (this causes problems later on otherwise)
# But first we will add a new apt source
