BIS 4875 STM: How do myself and my family manages our digital (intangible) assets?

there are two main way to manages our digital (intangible) assets: encryption and backup (online backups and local backups)

In my home, most of the intangible property are I and my father management together, now many are run by me.

encryption

RAR files

For documents and television which part will be not used for a long time, my family will change all those files compress in to *.RAR and make the password by ourselfe, password is belong to who have the files (like I just know my file's password), then make a backup.

backups

In my family, my father and I hvae quite different for the management of intangible assets.

My father prefers to hold everything by himrself, not to the WeChat(like LINE, or FACEBOOK), he likes to lock his computers, electronic devices add password, to protect the itangible assets.

And he like online backup, my father have a backup account in 115.com cloud network, he saved lots of our family files , like recording, audio and photos (full backup).

He thought it would be better to protect our family of intangible assets.

Earlier in 2012, my father give his account of the network to me , the family account management and use by me now.

I prefer the local backup,like mobile hard disk, or other storage devices.I think the backup in the network, data will not be safe, may have been cracked or read, and if we want to use to see the files , it should be base on network situation, even the network speed, it takes a long time to read.
Local data storage can be better management and more easy and faster to read.
