Question
I own a small private server (@home) with all necessary features for my backup purposes (Owncloud, SVN, GIT).
My target now is to ensure the safety of my data in emergency cases like fire/flood. For this i want to rent or use a free online cloud storage (dropbox,strato,...). My server should backup there all important data on a weekly basis. Sadly the CPU, older Atom dualcore, has not enough performance to work on heavy load tasks.
Which file format or technique should i use to upload the data in a way no other system can read it? I thought about implementing an own small crypt software for it but at first i want to here your comments.
Explanation / Answer
There are a number of providers available for this. You want to make sure that the provider you select has built in encryption options for which you can maintain the key. The below providers all support this.
Crashplan
BackBlaze
Remember that you need configure the software to use an encryption key you have generated yourself and keep this secure and safe. If you lose this key your backups are gone. It might be a good idea to invest in a safe deposit box or a fire proof safe.
