Duplicity backups to Backblaze B2 (Linux)
PROBLEM: I would like to backup files to the cloud.
SOLUTION: Pick Backblaze B2 with awesome pricing.
1.0 Create Application Key
Using official guide – https://help.backblaze.com/…Account-ID-and-Application-Key
Backblaze has a very easy and intuitive interface, so I bet you don’t need any guide to do it 🙂
2.0 Connection String
|
1 |
b2://[account id]:[application key]@[B2 bucket name] |
You should substitute real keys with variables, just to make the string more flexible. E.g.:
|
1 2 3 4 |
export ACC_ID="00011112223aaa" export APP_KEY="AAABBBCCCDDD000" b2://$account_ID:$application_key@my-fav-bucket/folder/ |
3.0 – Duplicity
3.1 Backup
Using Duplicity to Backblaze is very simple! You just need to generate GPG key (GUIDE: https://help.github.com/…/generating-a-new-gpg-key/). And I put the key ID as a variable $GPG_KEY. And here we go!
Duplicity makes incremental backup on the top of the full backup. So every time you run this command you will increment the first full backup.
|
1 |
duplicity --verbosity info --encrypt-sign-key=$GPG_KEY /directoryToBackup b2://$account_ID:$application_key@my-fav-bucket/backup-folder/ |
3.2 Restore
Restore is very similar to backup. The string is almost the same.
|
1 |
duplicity restore --file-to-restore [folder name from backup] b2://[account id]:[application key]@[B2 bucket name] [restore path] |
So in my case:
|
1 |
duplicity restore --file-to-restore /backup-folder b2://$account_ID:$application_key@my-fav-bucket/ /restored-data-folder |
And that is it! You can create a CRON rule to run backups on a regular basis or anything you’d like to!
