How to manage backups when developing websites as freelance?
- I have my clients purchase web hosting space from a provider of their choice.
- I develop the website and upload it to their hosting space.
- Provide option of extended technical support.
ADDED:
The websites tend to be dynamic with various data stored into the database.
I am unable to routinely backup the dynamic sites because a) it is too time consuming and b) too costly for my clients. Ideally I need to offload that liability because if a server fails (or provider ceases to exist) and backups are also lost, how are my clients going to recover?
Should my clients be downloading backups and storing them in a safe place?
Likewise upgrading WordPress releases occasionally introduce breaking changes that require plugins to be updated. What is the best practice for charging for WordPress upgrades?
