indieServe is hosting for KWLUG, KWVoIP, FairvoteWRC, KWPeace, &c.
About $10/month for shared host
- No limits but on the honour system
- Keep it to one company per shared host
- Local non-profits may be able to get really good deal -- talk to Mark Steffen
Also has VPS (Virtual Private Servers)
Can do hosted Windows servers or domain
- Good for small file sharing systems
- Microsoft has a specific licensing arrangement for hosting providers
- Cost based on cores and sockets, plus number of customers
- Not cheap, $100's /month
- Similar model to Azure or Amazon AWS

Some customers use offsite hosting only for data replication (disaster recovery)
- Do keep offsite backups encrypted
- For any backup solution check with Legal for PIPEDA legislation
- Cheap backup? 20¢/GiByte for storage is typical
Backup software:
- Duplicity for Linux
- Cloud Berry for backup service
- DupliCaddy for Windows (Open Source, Beta software,supports SQL, kinda slow)
  - For Windows, do full backup, then everything is incremental afterwards
  - But it keeps a synthetic "Full" in the background
- With S3 or Azure, you can restore to EC2 -- get (almost) instant restore on external VPS -- really cheap disaster recovery
- Back Blaze (personal backup for $5/month, also B2 backup storage, .02¢/Gibyte?, $10/month for 1 TByte?)

Hijacked truck (backups not encrypted, nobody knows who now has access to backup data)
Encrypted backups corrupted (physical disk damage corrupted one block of data, cypher block chaining made rest of backup inaccesible)
Bulk files corrupted (backup file is OK, but contained invalid data, making rest of the backup invalid)
Tape backup is still the most dense storage for immutable backups
Mark Steffen has techniques for redundant backup storage (good for ransomware attacks, &c.)
How much backup do you need?
- How much data can you afford to lose?
- Have at least one automated backup in place

Run your own service on a VPS or shared host (XMPP, Wiki, Social media) instead of using Facebook, Google, Twitter)
Manage your own server, colocated in a datacentre
Getting a DSL line (with multi-link support), and running a server on premises
Managed hosting - servers in house or colo, but contract out the SysAdmin

Set up WordPress, &c.
Handles updates, patch management, backups, email
Installatron for managing applications
Varnish is a cache in front of Apache, for bursty traffic
cPanel is pricey? $20/month for bare metal, less for a VPS
- Keeping cPanel on a VPS makes it portable, allows cPanel admin to perform maintenance with no downtime

CentOS Web Panel
ISP Config
Ubuntu MAAS
WebMin, VirtualMin
WHM is the management tool for cPanel
WHMCS is a shopping cart / billing system for hosting
- But these apps may have security issues (PHP doncha know)

Perhaps for Web developers, who want to manage resources for their customers
Can add multiple accounts, lets hosting provider manage growth and resources
Could be unlimited accounts, but typically 300 GBytes, good for about 50 accounts
