coalescence
I know I'd personally chose maintaining the system packages and where possible put extraneous language dependencies in packages too (fpm comes in handy as it can deal with a variety of packages, gem, npm etc). It makes life a lot simpler when it comes to administering a bunch of systems and trying to keep things consistent.

In reality though, more companies do this than should be allowed. I worked for an ISP in a previous life and even on the super cheap shared hosting there were companies that were making a decent turnover and then using the cheapest possible hosting for their email/site. The quantity of these companies was a significant number too.
Especially when they were kicking off on the phone due to inevitable maintenance/downtime. Trying to appease customers that turn over 10 million a year and pay £5 a month for hosting is a bit wtf. You pay for what you get... that's no different in hosting.
Usually there are backup options included in the plan for upsell possibilities with these kinds of providers. Really, you should not expect a service that has 'cheap' in the name to offer any kind of backup.
Also, the images being stored in .rar format is a little crazy. I'm not sure why that's the case when there are a plethora of other compression formats more generally used for binary image compression.
