Good Practices

Automatic Push to Private Storage

Any good solution should have the following steps:

1. Read data as soon as possible from device
   • daily/with WIFI/with power on
2. Write data as soon as possible into a RAID1 storage

It will be easy to use a transport technology via available cloud solutions:

• Google Drive (be sure to disable the Camera Upload with changed resolution)
• Dropbox (Camera Upload is disabled if you don't pay)
• Synology DS Files (free, but a little harder to configure: see the server from internet) It will be easy to use a storage from a well known, reliable NAS provider:
• Synology

Bad Practices

Saving Data On Devices Internal Storage

The device can be lost, bricked, destroyed, accidentally deleted. Besides android takes great lengths in protecting the internal storage: you can read application data only if rooted. Or with adb if the developer enables backup of data at google.

Saving Data On Devices External Storage

The external card can be lost, stolen, bricked. SDCards are particularly susceptible at getting bricked without any possibility to recover data from them. If you choosed an encrypted card then you cannot get data out of that card.

Saving Data On noRAID or RAID0 Storage

The HDD are known to fail in time

Saving Data On CDROM/DVDROM/FlashDisks/SDD/Laptops/SDCards Storage

Saving Data On Cloud Only Storage

The cloud provider might change the rules along the way, including by declaring bankruptcy. What happens with your data then? Yeah, sure: Google, Apple, Microsoft will not become bankrupt. But countries could put up firewalls, big companies change their policies, declare end of data for various products, etc.

Apple Cloud

The service offered by apple: iCloud. Apple has a history of deleting data from devices: mp3s. Is doing this including for bought mp3s. From them.

Google Cloud

You don't have access to the full backup data saved by your own android device. You will get that back if you have a similar device. How many versions? What about transferring data to other devices? For how long? What about bought applications that are discontinued?

Amazon Kindle

Amazon has a history of remotely deleting data from kindles.
