Cheap cloud backup with encryption for home

I greet you, Habrayuzer! I'm going to tell you about the C14 cloud storage and a small utility that facilitates the routine work when working with the features of this storage.


Looking ahead to say that the cost of storing 1 TB is 2 euros per month. This storage has already been mentioned earlier on Habré: The nuclear bunker in Paris will be converted into a data center company online.net

C14 Storage

If you are familiar with C14, you can skip this part and go to the next one.

Online.net has a wide variety of services and several repositories. We are only interested in C14. Take money for storage, removal, opening of the archive. You can estimate your expenses approximately on their website. By operations we mean archiving, deleting and opening an archive with files.

The following scheme of work with storage is proposed:

We can create quite a few repositories in C14 (here, and hereinafter referred to as safe in their terminology). Each repository may have several archives. Archive (archive) - this is the OS with limited access. You can connect via sshfs, rsync, scp, ftp, webdav . The archive is available for connection within 2, 5 or 7 days, after that it will be automatically archived and placed very deep in the bunker. If you need to recover data, a new OS will be created and all your previously saved files will appear in the /buffer folder. If you try to change the restored archive, the contents will be copied and the archive will be updated.

C14 Backup Tool

At first, I wanted to put all the code in one file, but the reality turned out to be much harsher, so I decided to share with all my decision.

What utility can:

• Encrypt data on the client side.
• Do not backup the specified folders. In this case, rsync regular expressions are available only in non-encrypted mode.
• Automatically create safe archives, put access keys there and delete outdated archives.
• And also, create incremental backups within a single archive to reduce storage costs.
• Each archive is a fully working backup. Therefore, they can be deleted without fear (if at least one line is written in the description of the archive with the date of successful archiving).
• Write large and not very xmpp logs.
• Does not require composer if you do not need xmpp logs.
• Several profiles for copying all sorts of data.
• Does not use the official program to access the API
• Saves the encfs config to each archive with data

What she does not know how:

• Thoroughly check the config and necessary dependencies
• Work if you have more than 100 safe or more than 100 archives in one safe.

Installation

To use you will need

rsync
encfs
sshfs
ssh

For xmpp logs you need composer (optional)

Downloading the script for those who do not have composer and do not need xmpp logs:

git clone https://github.com/TheSaturn/C14BackupTool.git
cd C14BackupTool
cp config.example.php config.php

Otherwise:

composer create-project thesaturn/c14-backup-tool
cp config.example.php config.php

Setup:

Register online at online.net . Add billing details . Generate ssh keys (if you don’t have them yet) via ssh-keygen . Edit config.php : you will need to enter the API key, select folders, etc. Run the script ( php /path/to/main.php profileName ) and wait for the message about the successful completion of the backup. Add script to cron at will

Cones:

API requests are not always applied instantly. Therefore, the code has a forced sleep() . Mounting over sshfs and connecting rsync does not always happen the first time either. The support throws up his hands and claims that everything is fine. Therefore, there are several attempts to connect to the repository.


I will be glad to answer your questions. Link to the repository .
